Register VDF in you Development machine
Licensing the VDF version 6 in your machine
If you are a customer and not an evaluator then in order to be able to use the VDF libraries (likevdFramedControl) and VectorDraw Professional 6.x Wrapper (vdraw.ocx) in your development platform you
should license/register it. This is done by using your Serial number of the version6 that is provided with thepurchase of the libraries and the vdAuthorizeApp.exe utility. You machine should be also connected to theinternet.

Run the vdAuthorizeApp.exe utility as administrator or as a user with administrative rights in yourDevelopment machine and type your VDF serial (case sensitive) and click the "Authorize" button. Check the"Result" window.

If you like to install and authorize the libraries in another machine like a presentation laptop PC then you
should Unauthorize your development machine and Authorize it again on the laptop. You cannot havemultiple machines authorized simultaneously with the same license. If you don't have access to the Internet
or you having troubles with this procedure then contact our sales department including the result you get.

Getting Started - ActionUtility - vdFramedControl
The ActionUtility Object can be used in order to ask the user to input data in the application, like a point, a
rectangle, a distance etc.
For example if you like the user to input a point in the drawing the you can call a code like :gPoint userpoint;
vdFC.BaseControl.ActiveDocument.Prompt("Select a Point:");//The user can either click a point or type at the command line a point like
5,5,2
StatusCode ret =vdFC.BaseControl.ActiveDocument.ActionUtility.getUserPoint(out userpoint);
vdFC.BaseControl.ActiveDocument.Prompt(null);
if (ret == StatusCode.Success){
MessageBox.Show("The user selected: x:" + userpoint.x.ToString() + " y:" +userpoint.y.ToString() + " z:" + userpoint.z.ToString() + " In UCS(usercoordinate system)");}The above sample code can be changed so the user is asked for a second point and then create a rectangle
from these two points. Like :vdFC.BaseControl.ActiveDocument.New();
gPoint userpoint;
vdFC.BaseControl.ActiveDocument.Prompt("Select a Point:");//The user can either click a point or type at the command line a point like
5,5,2
StatusCode ret =vdFC.BaseControl.ActiveDocument.ActionUtility.getUserPoint(out userpoint);
vdFC.BaseControl.ActiveDocument.Prompt(null);
if (ret == StatusCode.Success){
MessageBox.Show("The user selected: x:" + userpoint.x.ToString() + " y:"+ userpoint.y.ToString() + " z:" + userpoint.z.ToString() + " In UCS(usercoordinate system)");}vdFC.BaseControl.ActiveDocument.Prompt("Other corner:");//The user can either click a point or type at the command line a point like
5,5,2
object ret2 =vdFC.BaseControl.ActiveDocument.ActionUtility.getUserRect(userpoint);
vdFC.BaseControl.ActiveDocument.Prompt(null);
Vector v = ret2 as Vector;
if (v != null) {double angle = v.x;
double width = v.y;
double height = v.z;//Calculate the point the user clicked.
//Use polar command to find the bottom right point moving width distancefrom the initial point.
gPoint userpoint2 = userpoint.Polar(0.0, width);//Use the polar again to go up height distance to find the upper rightpoint.
userpoint2 = userpoint2.Polar(VectorDraw.Geometry.Globals.HALF_PI,
height);MessageBox.Show("The user selected 2nd point : x:" +userpoint2.x.ToString() + " y:" + userpoint2.y.ToString() + " z:" +userpoint2.z.ToString() + " In UCS(user coordinate system)");vdFC.BaseControl.ActiveDocument.CommandAction.CmdRect(userpoint,userpoint2);}

Getting Start Guide VDF vdFramedControl version 6
Getting Started - Blocks - vdFramedControl
A block is a collection of objects you can associate together to form a single object, or block definition. You caninsert, scale, and rotate a block in a drawing (this is called vdInsert). You can explode a block into its
component objects, modify them, and redefine the block definition. The use of Blocks streamline the drawing
process. For example, you can use blocks to build a standard library of frequently used symbols, components,or standard parts.
You can insert the same block numerous times instead of re-creating the drawing elements each time. Revise
drawings efficiently by inserting, relocating, and copying blocks as components rather than individual
geometric objects. Save disk space by storing all references to the same block as one block definition in thedrawing database. When you insert a block in your drawing, you are creating a block instance. Each time you
insert a block instance, you assign a scale factor and rotation angle to the inserted block. You can also scale a
block instance using different values in any coordinate (X, Y, Z) direction. Blocks make it possible for you toorganize your drawing tasks in a systematic way, so that you can set up, redesign, and sort the objects in yourdrawings and the information associated with them.
Below is a sample code that will add an new Block (vdBlock) object in the drawing named "CustomBlock" andalso an existing drawing (drawing is named vdblk.vdml) as "CustomBlock2" :private void AddBlockItems(){//We create a block object and initialize it's default properties.
VectorDraw.Professional.vdPrimaries.vdBlock blk = new
VectorDraw.Professional.vdPrimaries.vdBlock();
blk.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
blk.setDocumentDefaults();//We add some entities to the block.
VectorDraw.Professional.vdFigures.vdPolyline poly = new
VectorDraw.Professional.vdFigures.vdPolyline();poly.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
poly.setDocumentDefaults();
poly.VertexList.Add(new VectorDraw.Geometry.gPoint());
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(1.0,0.0));
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(2.0,1.0));
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(4.0,-1.0));
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(6.0,1.0));
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(8.0, -1.0));
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(10.0, 1.0));
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(11.0, 0.0));
poly.VertexList.Add(new VectorDraw.Geometry.gPoint(12.0, 0.0));
blk.Entities.AddItem(poly);
blk.Origin = new VectorDraw.Geometry.gPoint(6.0, 0.0);
blk.Name = "CustomBlock";
VectorDraw.Professional.vdFigures.vdAttribDef attribdef = new
VectorDraw.Professional.vdFigures.vdAttribDef();
attribdef.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
attribdef.setDocumentDefaults();
attribdef.InsertionPoint = new VectorDraw.Geometry.gPoint(5.0,1.2);//Name of the attribute used to be found when using the block.
attribdef.TagString = "resistance";//Default value used when inserted the block from the block's dialog.
attribdef.ValueString = "1W";
blk.Entities.AddItem(attribdef);//And then we add this block to the document's blocks collection
vdFC.BaseControl.ActiveDocument.Blocks.AddItem(blk);//We will also add a block from a precreated file.
string path = Application.ExecutablePath.Substring(0,Application.ExecutablePath.LastIndexOf('\\')) + "\\..\\..\\vdblk.vdml";
string path1 = "";VectorDraw.Professional.vdPrimaries.vdBlock blk2;
if (vdFC.BaseControl.ActiveDocument.FindFile(path, out path1)){
blk2 = vdFC.BaseControl.ActiveDocument.Blocks.AddFromFile(path,false);//We check if a block with name CustomBlock2 already exists and if not
we change the name of the block to CustomBlock2.
if (vdFC.BaseControl.ActiveDocument.Blocks.FindName ("CustomBlock2")== null) blk2.Name = "CustomBlock2";}}
You can see the existing block in a drawing and also insert them using the InsertBlockDIalog:

private void OpenBlocksForm(){
VectorDraw.Professional.Dialogs.InsertBlockDialog form =VectorDraw.Professional.Dialogs.InsertBlockDialog.Show(vdFC.BaseControl.ActiveDocument,
vdFC.BaseControl.ActiveControl, false, "");
if (form.DialogResult == DialogResult.OK){if (form.insertionPoint is double[]){double[] pt = form.insertionPoint as double[];form.insertionPoint = new VectorDraw.Geometry.gPoint(pt[0],pt[1],pt[2]);}if(form.scales is string)
vdFC.BaseControl.ActiveDocument.CommandAction.CmdInsert(form.blockname,form.insertionPoint, form.scales, form.scales, form.rotationAngle);else{
double[] scales = form.scales as double[];vdFC.BaseControl.ActiveDocument.CommandAction.CmdInsert(form.blockname,form.insertionPoint, scales[0], scales[1], form.rotationAngle);}}//The dialog can also be called using the CmdInsertBlockDialog command.
//vdFC.BaseControl.ActiveDocument.CommandAction.CmdInsertBlockDialog();}

You can also insert the blocks created in AddBlockItems() using a code like :private void AddInsertObjects(){//We will add 5 instances(inserts) of each block to theDocument with different properties.
//First we check if the blocks have been already added to theblocks collection.
if (vdFC.BaseControl.ActiveDocument.Blocks.FindName("CustomBlock") !=null){
VectorDraw.Professional.vdFigures.vdInsert ins;for (short i = 0; i < 5; i++){ins = new VectorDraw.Professional.vdFigures.vdInsert();ins.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
ins.setDocumentDefaults();

ins.InsertionPoint = new VectorDraw.Geometry.gPoint(i * 10, 10);
ins.PenColor.ColorIndex = i;
ins.Rotation = VectorDraw.Geometry.Globals.HALF_PI/2.0 * i;//This will create the necessary vdAtrib objects to theinsert.
ins.CreateDefaultAttributes();//Now we will change the value of the attribute
if (ins.Attributes.Count == 1) ins.Attributes[0].ValueString =i.ToString() + "W";//And we add the entities to the Model Layout.
vdFC.BaseControl.ActiveDocument.Model.Entities.AddItem(ins);

ins.InsertionPoint = new VectorDraw.Geometry.gPoint(i * 10, 10);
ins.PenColor.ColorIndex = (short)(i*40+10);
ins.Xscale = 2.0;
ins.Yscale = 2.0;
ins.Rotation = -VectorDraw.Geometry.Globals.HALF_PI * i;//Since the active Layout is the model adding thisinsert to the Model or the ActiveLayout is the same thing.

Getting Started - Colors & Palette - vdFramedControl
Graphical objects in VectorDraw can have a specific pencolor. This color can be an RGB (Red Green Blue) value or a
specific color index from the VectorDraw pallete. The color of an object can also take some specific values that canbe "Color by Layer" or "Color by Block" where the object takes the color specified by the layer that is or the block.
Some object may be filled (like circles or polylines) and the fill color of these objects might be transparent (alphablending).
See the following code:

private void AddSomeEntities(){
vdCircle circ = new vdCircle();vd.BaseControl.ActiveDocument.ActiveLayOut.Entities.AddItem(circ);
circ.setDocumentDefaults();
circ.PenColor.SystemColor = Color.Red; // Using system color
circ.Center = new gPoint(5, 5);
circ.Radius = 2;
circ = new vdCircle();vd.BaseControl.ActiveDocument.ActiveLayOut.Entities.AddItem(circ);
circ.setDocumentDefaults();
circ.PenColor.ColorIndex = 1; // Using pallete's color
circ.Center = new gPoint(10, 5);
circ.Radius = 2;

Getting Started - CommandAction - vdFramedControl
The CommandAction object offer to the developer a variety of tools in order to do some user specificactions. For example developer may wants to offer to the end user the ability to add lines with points thatthe user selects. In this case the only code that is required by the developer is to call cmdLine with "USER"
parameters, like:

vdFramedControl1.BaseControl.ActiveDocument.CommandAction.CmdLine(null);//parameter null means that the user will pick the required point- distanceor everything that is required for the command.
There are also these commands that allow the user to add entities like CmdXLine, CmdRay, CmdPoint,
CmdArc, CmdCircle, CmdEllipse, CmdPolyLine, CmdText, CmdRect, CmdImage, CmdDim, CmdBox3d,
CmdSphere, CmdCone, Cmd3DMesh, Cmd3dFace and CmdPlineToMesh.

CommandAction has functionality to manipulate entities like copying, moving, deleting them etc. Like :vdFramedControl1.BaseControl.ActiveDocument.CommandAction.CmdCopy(null, null,null);//This will prompt user to select entities and copy them from one point toanotherDeveloper can use : CmdRotate, CmdCopy, CmdErase, CmdMove, CmdExplode, CmdMirror, CmdBreak,CmdOffset, CmdExtend, CmdTrim, CmdFillet, CmdStretch, CmdArrayPolar and CmdArrayRectangular,
CmdClipCopy, CmdClipPaste, CmdClipCut for editing/manipulating entities using CommandAction.

Besides the above functions CommandAction has viewing functionality like zooming to the whole document
or to a small window, change the 3D view etc. You can zoom to a user selected window like :vdFramedControl1.BaseControl.ActiveDocument.CommandAction.Zoom("w", null,null);//This will prompt user to select entities and copy them from one point toanotherDeveloper can use : Zoom, Pan, View3D, UCS to change the view of the document.

You can see the "Commands" sample of the vdFrameWork samples collection. This sample demonstrates theuse of predefined commands that can be used to draw graphic objects like lines, circles etc (cmdLine,
cmdCircle etc) and also transform these objects like Copy, Move, Rotate etc.

Getting Started - Dimensions - vdFramedControl
Dimensioning is the process of adding measurement annotation to a drawing. User has many ways to dimension objects and many ways
to format dimensions. You can create dimensions for a wide variety of object shapes in many different orientations. You can create
dimension styles to format dimensions quickly and ensure that dimensions in your drawing conform to industry or project standards.
Dimensions show the measurements of objects, the distances or angles between objects, or the distance of a feature from an origin you
specify. User has three basic types of dimensioning: linear, radial, and angular. Dimensions can be horizontal, vertical, aligned, rotatedor angular. A linear dimension measuring the distance between two points which is displayed parallel to the points being measured. Inaligned dimensions, the dimension line is parallel to the extension line origins. The extension line origins are specified using the
DefPoint1 and DefPoint2 properties.

Angular dimensions measure the angle between two lines or three points.
Dimensions use an existing DimStyle in order to display the lines and the texts/numbers of the dimension, see in this article.
You can also add dimensions with code like below (prior to this you should run the code in this article) :private void AddDimensions(){
string dimname = "DimStyle1";
VectorDraw.Professional.vdPrimaries.vdDimstyle style =vdFC.BaseControl.ActiveDocument.DimStyles.FindName(dimname);if (style == null)style = vdFC.BaseControl.ActiveDocument.DimStyles.Standard;
VectorDraw.Professional.vdFigures.vdDimension dim1 = new

dim1.LinePosition = new VectorDraw.Geometry.gPoint(7.0, 5 * i + 4.0);
dim1.Rotation = 0.0;//We set the dim style that we found before.
dim1.Style = style;//We add the object to the model entities collection

dimension, use the Style property found on the dimension.
When you create a dimension, the current dimension style is associated with that dimension. The dimension retains thisdimension style unless you apply a new dimension style to it or set up dimension style overrides.
The picture below shows where the vdDimstyle's properties apply to vdDimension objects.

In the DimStyle you can use an existing TextStyle in order to display the texts/numbers of the dimension, see in this article.
You can see them using the DimStyle's dialog :private void OpenDimStylesDialog(){
VectorDraw.Professional.Dialogs.frmDimStyle.Show (vdFC.BaseControl.ActiveDocument);}
You can also create your own DimStyles with code like below:

private void AddDimstylesItems(){//We create a vdDimstyle object.
VectorDraw.Professional.vdPrimaries.vdDimstyle style1 = new
VectorDraw.Professional.vdPrimaries.vdDimstyle();style1.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);style1.setDocumentDefaults();//And change some properties.
style1.Name = "DimStyle1";style1.TextColor.ColorIndex = 1;style1.TextHeight *= 4.0;//And add this object to the Dimstyles collection of the document.
vdFC.BaseControl.ActiveDocument.DimStyles.AddItem(style1);//We can also add dimstyles using the Add function of the dimstyles collection which is mucheasier.

VectorDraw.Professional.vdPrimaries.vdDimstyle style2 =vdFC.BaseControl.ActiveDocument.DimStyles.Add("DimStyle2");style2.ExtLineVisible = false;
VectorDraw.Professional.vdPrimaries.vdDimstyle style3 =vdFC.BaseControl.ActiveDocument.DimStyles.Add("DimStyle3");style3.ExtLineColor.ColorIndex = 1;style3.DimTol = true;style3.DimTp = 0.3;
style3.DimTm = 0.3;}

TextStyle is a named, saved collection of settings that determines the appearance of text strings. You cancreate your own text styles which can have specific fonts and text height. You can also specify if the texts(vdText/vdMText) will be underlined,bold etc. There is no limit to the number of text styles you can create inyour drawing. When you enter text, it uses the current text style, which sets the font, size, and other text
characteristics. If you want to create text using a different text style, you can make another text styleactive.
In the TextStyle you can use Windows TTF fonts or CAD fonts named SHX fonts. More information regardingthese you can see in this article.
You can see them using the TextStyle's dialog :private void OpenTextstylesDialog(){
VectorDraw.Professional.Dialogs.frmTextStyle.Show(vdFramedControl1.BaseControl.ActiveDocument);}
You can also create your own TextStyles with code like below:

private void AddTextstylesItems(){//We add a textstyle with font name Verdana.
VectorDraw.Professional.vdPrimaries.vdTextstyle style1 = new
VectorDraw.Professional.vdPrimaries.vdTextstyle();style1.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);style1.setDocumentDefaults();style1.Name = "TextStyle1";style1.FontFile = "Verdana";
vdFramedControl1.BaseControl.ActiveDocument.TextStyles.AddItem(style1);//You can also add Textstyles using the Add function of the collection which
is much easier.
VectorDraw.Professional.vdPrimaries.vdTextstyle style2 =vdFC.BaseControl.ActiveDocument.TextStyles.Add("Textstyle2");style2.Extra.IsUnderLine = true;style2.Extra.IsStrikeOut = true;style2.FontFile = "isocr.shx"; //This TextStyle will use a CAD SHX font.

Getting Started - Document Properties & Events - vdFramedControl
The VectorDraw Document object (named vdDocument Class; check also the "vdDocument Class" topic in our VDF Help file) is the
top-most object in the drawing and of course the basic object. It has many properties and methods. Some properties of Document
object (and ActiveLayout) are used in order to change the view/appearance of the document, like the "RenderMode" property,
the "ViewCenter" & "ViewSize" properties, the "Palette" etc. It also contains information regarding the interface, like
"OsnapMode" and "OrthoMode", "SnapAngle, SnapBase, SnapIso" and similar properties. It is also containing the tablecollections of the drawing like the "TextStyles, DimStyles, Layers, Blocks etc" that are used in the drawing. And of course it
contains the basic I/O functions like Open and Save.
You can also see topics: "vdDocument Class", "vdDocument Class, Methods", "vdDocument Class, Properties" and "vdDocument
Class, Overview" in our VDF help (VDF.CHM).
The VectorDraw Document object has events that the developer can use to customize his/her application. The complete list ofthese events and also a brief description can be found in our VDF Help file under "vdDocument Class Events " topic, check also the"vdDocument Class" topic.
Lets see a simple example. We will add a form and a button. In the button click a cmdLine with user input will be run :private void btLine_Click(object sender, EventArgs e){//the code bellow will start a cmdLine command that waits the user to input the points
this.vdSC.BaseControl.ActiveDocument.CommandAction.CmdLine("USER");}
While this command is running and the user inputs points a "rubber" line is displayed. This example will also draw another"rubber" entity that will be a circle besides the rubber line. The Event that fires while the command is active is the OnActionDraw(the action is the cmdLine). So we have to "define" the event in the Form Load, likeprivate void Form1_Load(object sender, EventArgs e){//The Form1_Load runs when the program starts. Here we will define the OnActionDraw event
vdFC.BaseControl.ActiveDocument.OnActionDraw += new
VectorDraw.Professional.vdObjects.vdDocument.ActionDrawEventHandler(ActiveDocument_OnActionDraw);}
After this we have to add the code to the OnActionDraw event that will draw the rubber circle along with the rubber line that is
drawn automatically by the cmdLine. The code :void ActiveDocument_OnActionDraw(object sender, object action, bool isHideMode, ref boolcancel){//This code will run on every Action draw
if (!(action is VectorDraw.Actions.ActionGetRefPoint)) return; //if the action is not an"input point" then exit
VectorDraw.Actions.BaseAction act = action as VectorDraw.Actions.BaseAction;
VectorDraw.Geometry.gPoint refpoint = act.ReferencePoint; //This is the base point
VectorDraw.Geometry.gPoint currentpoint = act.OrthoPoint; //This is the cursor position
VectorDraw.Professional.vdFigures.vdCircle circle = new
VectorDraw.Professional.vdFigures.vdCircle();circle.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
circle.setDocumentDefaults();
circle.Center = VectorDraw.Geometry.gPoint.MidPoint(refpoint, currentpoint);
circle.Radius = circle.Center.Distance3D(refpoint);
circle.Draw(act.Render);}Now lets see a different kind of event, the OnAfterAddItem event that fires after an entity is added to the document collection. We
will use this event to add also a rectangle (vdRect Object) to the document. This rectangle will be round the line that was addedwith cmdLine code. First we will have to "define" this event in the form load too:

private void Form1_Load(object sender, EventArgs e){//The Form1_Load runs when the program starts. Here we will define the events
vdFC.BaseControl.ActiveDocument.OnActionDraw += new
VectorDraw.Professional.vdObjects.vdDocument.ActionDrawEventHandler(ActiveDocument_OnActionDraw);
vdFC.BaseControl.ActiveDocument.OnAfterAddItem += new
VectorDraw.Professional.vdObjects.vdDocument.AfterAddItemEventHandler(ActiveDocument_OnAfterAddItem);
vdFC.BaseControl.ActiveDocument.OnGetGripPoints += new
VectorDraw.Professional.vdObjects.vdDocument.GetGripPointsEventHandler(ActiveDocument_OnGetGripPoints);
vdFC.BaseControl.ActiveDocument.OnAfterOpenDocument += new
VectorDraw.Professional.vdObjects.vdDocument.AfterOpenDocument(ActiveDocument_OnAfterOpenDocument);}
And add this code :void ActiveDocument_OnAfterAddItem(object obj){//After a vdLine is added we will also add a rectangle.
VectorDraw.Professional.vdFigures.vdLine line = obj as
VectorDraw.Professional.vdFigures.vdLine;if (line == null){
return;}else{//Draw a rectangle around the vdLine that was previously added
VectorDraw.Professional.vdFigures.vdRect onerect = new
VectorDraw.Professional.vdFigures.vdRect();//We set the document where the rect is going to be added.This is important for the
vdRect in order to obtain initial properties with setDocumentDefaults.
onerect.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
onerect.setDocumentDefaults();//The two previus steps are important if a vdFigure object is going to be added to a
document.
//Now we will change some properties of the rect.
onerect.InsertionPoint = line.StartPoint;
onerect.Width = line.EndPoint.x - line.StartPoint.x;
onerect.Height = line.EndPoint.y - line.StartPoint.y;
onerect.PenColor.ColorIndex = 34;////Now we will add this object to the Entities collection of the Model
Layout(ActiveLayout).
vdFC.BaseControl.ActiveDocument.ActiveLayOut.Entities.AddItem(onerect);onerect.Invalidate();}}Now lets add an extra grip point to the lines we draw. In this case the OnGetGripPoints event will be use like :void ActiveDocument_OnGetGripPoints(object sender, VectorDraw.Geometry.gPoints gripPoints, refbool cancel){
VectorDraw.Professional.vdFigures.vdLine line = sender as
VectorDraw.Professional.vdFigures.vdLine;if (line != null){
VectorDraw.Geometry.gPoint pt = new VectorDraw.Geometry.gPoint();
pt = VectorDraw.Geometry.gPoint.MidPoint(line.StartPoint, line.EndPoint);
gripPoints.Add(line.StartPoint);
gripPoints.Add(line.EndPoint);
gripPoints.Add(pt);//To cancel the VDF component code that adds the startpoint and endpoint after thisevent
cancel = true;}}
The OnAfterOpenDocument event is fire after the user opens a drawing. In the example below, a message box will be shown with
the number of the entities of the ActiveLayout and also the UCS axis icon will be hidden :void ActiveDocument_OnAfterOpenDocument(object sender){// Show the activelayouts' entities count and hide the UCS axis icon.
MessageBox.Show("In this drawing (activelayout) are : " +vdFC.BaseControl.ActiveDocument.ActiveLayOut.Entities.Count + " entities \r\nUCS Axis will behidden.");vdFC.BaseControl.ActiveDocument.ActiveLayOut.ShowUCSAxis = false;}Product : Engine - vdFrammedControl, Version : 6

Getting Started - Drag & Drop - vdFramedControl
The VectorDraw Developers Framework library has extensive Drag & Drop capability and can be fully
controlled by the developer. The drag & Drop can produce a block to another VDF component, a picture in a
picture box or even a VectorDraw file when it is dragged to the desktop. In the following code we have aform with 2 VDF components (Source and Destination, named vdSource and vdDestination respectively) andan ImageButton component.
Clicking on the circle in the vdSource control and dragging it to the vdDest control and then release themouse then an insert will be added (a block also). Doing the same thing to the ImageButton control then abitmap will be generated and added to the ImageButton.
You can also drag from the vdSource control and drop to an explorer (or to the desktop) to create a vdml filewith the destination's entities. You can also drag a file from a file explorer and drop it to the the vdSource
control and it will be opened there.
You can check the Drag & Drop sample for a code like :private void CreateSourceEntities(){//create entities (in this case a circle) to drop over to the Source
BaseControl
vdCircle circle = new vdCircle();circle.SetUnRegisterDocument(vdSource.ActiveDocument);
circle.setDocumentDefaults();

Getting Started - Globalization of Resources - vdFramedControl
The VectorDraw Developers Framework version 6 .NET component can be localized in any language. Basicallythe words that are being localized are the prompt messages, the grid property names and also the forms. If
a customer wants to localize his VectorDraw component can contact with us and we will provide thefollowing:
1. vdRes.txt
vdRes.txt is a text document that contains all prompt messages and also all property names that are
being displayed in the property list. There he can translate these messages in any language.
2. vdFormsRes.dll, vdFormsRes project
vdFormsRes is a project that contains all forms of VDF component. In this project all labels and buttons
can be localized to any language. Also someone can change the appearance of the forms.
Limitations:-The constants in the property grid cannot be changed (e.g. PlFlagOPEN ,PlFlagCLOSE constant of thepolyline's flag property cannot be localized).
-You cannot add new buttons, labels at the vdFormsRes project.
New method added to get/set resource directory for commands.txt, menu.txt, vdres.txt
VectorDraw.Serialize.Activator.GetResourcesDirectory
VectorDraw.Serialize.Activator.SetResourcesDirectoryThis directory is set by application (when the application is loaded) and the component searches thisdirectory for the resource files Commands.txt, Menu.txt and vdres.txt.
Also in vdres.txt the first name represent a property name and if the second value is '-' (minus symbol) thenthe property is hidden from property grid.
If you want to use the vdFormsRes.dll in order to load your own forms then you should set the directory that
this dll is located in the vdres.txt at GlobalizedFormsDirectory with full path and dll name at the beginning of
the text document.

Getting Started - Grips - vdFramedControl
Grips are small, squares that are displayed at strategic points on objects that you have selected with yourmouse. You can drag these grips to edit the object(s) (stretch, move, rotate etc) quickly. The picture below
shows the default Grip points that are displayed on some vdFigures:

VectorDraw automatically shows the Grips on objects that are click if the EnableAutoGripOn is true. The
EnableAutoGripOn property is a value representing if the mouse click will show the grips of the entities andalso if the window Select command will start when the user click's to the control and there is no Entity
below.
You can also show the grips of an entity if the EnableAutoGripOn is false, using code in this article.
You can change the size or the color of the grips that are displayed using the GripColor and GripSize of
vdRenderGlobalProperties.
VectorDraw has the ability to create and display your own grips. For example you can add a mid-point grip
on vdLine object. See the following code :void ActiveDocument_OnGetGripPoints(object sender,
VectorDraw.Geometry.gPoints gripPoints, ref bool cancel){
VectorDraw.Professional.vdFigures.vdLine line=sender as
VectorDraw.Professional.vdFigures.vdLine;if (line != null){
VectorDraw.Geometry.gPoint pt = new VectorDraw.Geometry.gPoint();
pt = VectorDraw.Geometry.gPoint.MidPoint(line.StartPoint,line.EndPoint);

Getting Started - Handle - vdFramedControl
Handle is a unique hexadecimal number for every VectorDraw graphical object (like lines arcs etc) and for VectorDraw collections (like Layers,
Dimstyles etc). This number which is a read only property of string type is persistent (stays the same) in a drawing for the life time of theobject. Every time a drawing is opened the drawing's object's Handle are the same.
It is very useful when you want to "connect" a graphical object of your drawing to a data object in your database, for fast retrieving like when
you use FindFromHandle of vdDocument. See the simple example below :private void button1_Click(object sender, EventArgs e){
string Handle_circ = "";vdFC.BaseControl.ActiveDocument.New();

Getting Started - Hatches - vdFramedControl
Hatches and Solid fills are used when you want to show an area different from another area. For example in a
drawing that shows a house you can use a "GRASS" hatch to draw the garden of the house and a "CONCRETE" hatch
to show the road outside this house. There are some predefined hatches in the hatches collection that you can use
but you can also add your own hatches. Hatches consist of lines that can be Dashes (-), Dots (.) and Spaces ( ).
Beside hatching you can also fill an area with a specific fillcolor that can also be transparent, with a block or with animage.
Below is a sample code that will add a hatch pattern (named TEST_HATCH) with two lines to the existing hatch
collection:

private void AddHatchItems() {VectorDraw.Professional.vdPrimaries.vdHatchPattern myHatch = new
VectorDraw.Professional.vdPrimaries.vdHatchPattern();
myHatch.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
myHatch.setDocumentDefaults();
myHatch.Name = "TEST_HATCH"; //hatch is created and it is empty//Add 2 lines with dashes to the hatch pattern
myHatch.PatternLines.AddItem(new VectorDraw.DrawElements.grPatternLine(0.0d,
0.0d, 0.0d, 0.0d, 5.0d, new double[] { 3.0d, -3.0d }, false));myHatch.PatternLines.AddItem(newVectorDraw.DrawElements.grPatternLine(VectorDraw.Geometry.Globals.HALF_PI, 0.0d,
10.0d, 6.0d,0.0d, new double[] { 3.0d, -2.0d }, false));// OR you can do the same as below://myHatch.PatternLines.AddItem(new VectorDraw.DrawElements.grPatternLine(0.0d,
0.0d, 0.0d, 0.0d, 5.0d, new double[] { 3.0d, -3.0d }, false));//myHatch.PatternLines.AddItem(new VectorDraw.DrawElements.grPatternLine(90.0d,
0d, 10d, 0.0d, 6.0d, new double[] { 3, -2 }, true));// Important Notes: grPatternLine(angle, originX, originY, offsetX, offsetY,
double[] dashes, bool applytransforms)// - When you use the applytransforms = true then you have to use degrees (like90 degrees) and not radians (like PI/2) in the angle// - The point(OriginX,OriginY) remains the same as when you use
applytransforms = false// - When you use the applytransforms = true then the offset distance istranslated accordingly with the angle. In the above example the offset distance x:6& y:0 when is transformed by angle=90 becomes the opposite; x:0 & y:6//// - If you like to add a dot in the 1st line above then use something like ://myHatch.PatternLines.AddItem(newVectorDraw.DrawElements.grPatternLine(0.0d, 0.0d, 0.0d, 0.0d, 5.0d, new double[] {3.0d, -1.5d,0.0d,-1.5d }, false));myHatch.Update(); //Update the Hatch
vdFC.BaseControl.ActiveDocument.HatchPatterns.AddItem(myHatch); //add the hatch
to the collection}

Getting Started - Images - vdFramedControl
Image is a basic object for inserting images in the drawing. Inserted Images can be BMP, GIF, JPG, PNG andTIFF.
Image has a Scale property that is used to resize keeping the aspect ratio of the image. The image is definedby InsertionPoint, Rotation, Width and Height.
ImageDefs is the collection of the images used in the drawing. Every new image is added to this collection.
You can try a code like :private void AddImageItems(){//We will create an image and add it to the imageDef//First we create a black circle with radius 5.0 at (0.0,0.0,0.0).

Getting Started - Layers - vdFramedControl
Layer is the equivalent of the overlay used in paper-based drafting. It is the primary organizational tool in
VectorDraw, and you can use it to group information by function and to enforce linetype, color, and otherstandards.
Organizing Layers and the objects on Layers make it easier to manage the information in your Drawings.
When you put one layer over another then the result is the complete drawing.

Having kindred objects on the same layer it is very helpfull in order to organise the drawing.
Properties:●

layer name●color of the entities●

line type of the entities●

line weight of the entities●

if it is participate or not in the drawing (thawed or frozen)●

locked or not

When you begin a new drawing, VectorDraw creates a special layer named 0. By default, layer 0 is assigned
color number 6 (Foreground color : white or black depending upon your background color), the CONTINUOUS
linetype and a lineweight of Default (the default setting is .01 inch or .25 mm). Layer 0 cannot be deleted orrenamed.
All new objects are added to the active layer if no layer is specified. Using VectorDraw you can Freeze (Hide),Thaw (Show) and Lock layers. By controlling whether a Layer's state is Thaw or Frozen you can change theappearance of your drawing to display only the information on the Layers that are visible. Freezing unused
Layers will help the performance of VectorDraw.
In the drawing below (Picture 1) there are 3 types of items : walls (the lines and Polylines with red color),
doors&windows (Blue color) and furniture (Magenta).
These objects are teamed and drawn in different layers. Walls placed on layer "WALLS", Doors&windows areplaced on layer "WIN_DOORS" and furniture are placed on layer "FURNITURE".

Picture 1
All layers are Thawed. All information isshown.
In big drawings this might confuse the user.

Picture 2
Layer "FURNITURE" is Frozen. The furniture
is not shown.
A civil engineer would like to view thedrawing this way.

Picture 3
All layers except the "WALLS" are frozen.
This is the basic information.

You can see them using the Layers dialog :private void OpenLayersDialog(){VectorDraw.Professional.Dialogs.LayersDialog.Show(vdFC.BaseControl.ActiveDocument );}You can also create your own custom Layers. Like in the code below :VectorDraw.Professional.vdPrimaries.vdLayer lay = new
VectorDraw.Professional.vdPrimaries.vdLayer();lay.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
lay.setDocumentDefaults();
lay.Name = "Layer1";
lay.PenColor.SystemColor = Color.Red;

Getting Started - Layouts & Viewports - vdFramedControl
Layout is used to compose or lay out your model drawing for printing. A layout may consist of a title block,one or more viewports, and annotations. As you create a layout, you can design floating Viewportconfigurations to visualize different details in your drawing.
A layout is a paper space environment that simulates a sheet of paper. In a layout, you can create andposition viewport objects, and you can add a title block or other geometry. You can create multiple layouts ina drawing to display various views. Each layout displays the drawing as it will be printed on the sheet ofpaper.
Typically, when you begin designing a layout environment, you step through the following process:- Create a model drawing.
- Activate or create a layout.
- Insert a title block if is necessary.
- Create floating viewports and position them in the layout.
- Set the view scale and 3D view angle of the floating viewports.
- Print your layout.
Viewports are areas that display different views of your model. As you work, you can split the drawing area
into one or more adjacent rectangular views known as model viewports. In large or complex drawings,
displaying different views reduces the time needed to zoom or pan in a single view. Also, errors you might
miss in one view may be apparent into others. ViewPorts are treated as rectangle drawing objects whichdisplay views and can be moved or resized.
They can be created only in entity list collection of a layout and not in Model. Those rectangles filled with theimage of the model space objects in different scales depend from the ViewSize and the ViewCenter property.
This way in one paper you can print out different views (with different scales) of the same drawing (Model
Space) or parts of this drawing. In viewports commands like Pan, Zoom and View3D can be applied.
A sample picture of a Layout (Paper Space) with some Viewports:

Below is a sample code that will open an existing drawing and add layouts and viewports. The AddLayoutcode should be run before the AddLayoutEntities code :private void AddLayout(){//We open a drawing to the document that contains the info we like toshow.

Getting Started - MText & Text - vdFramedControl
The Text (vdText object) and MultilineText (vdMText) object are use to add text strings in your drawings. These texts
follow the TextStyle properties (which is a collection of settings) that determines the appearance of text strings. You
can also specify if the texts (vdText/vdMText) will be underlined,bold etc. When you enter text, it uses the current
text style, which sets the font, size, and other text characteristics. If you want to create text using a different text
style, you can make another text style active.
In the TextStyle you can use Windows TTF fonts or CAD fonts named SHX fonts.
You can easily add a text (vdText Object) using a code like :vdFC.BaseControl.ActiveDocument.CommandAction.CmdText(null, null, null);and a MultilineText like :vdFC.BaseControl.ActiveDocument.CommandAction.CmdMText(null, null, null);
The above commands can be used for simple texts or for user-input texts. You can add more complex texts andmultiline texts using vdText and vdMText objects like below.
You can add a vdText object with code like below:

private void butText_Click(object sender, EventArgs e){//We will create a vdText object and add it to the Active Layout which is thebasic//
Model Layout always existing in a Document.
VectorDraw.Professional.vdFigures.vdText onetext = new
VectorDraw.Professional.vdFigures.vdText();//We set the document where the text is going to be added. This is important
for the vdText//
in order to obtain initial properties with setDocumentDefaults.
onetext.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
onetext.setDocumentDefaults();//The two previous steps are important if a vdFigure object (like vdText) isgoing to be//
added to a document. Now we will change some properties of the text.
onetext.PenColor.ColorIndex = 3;
onetext.TextString = "Vectordraw Development Framework";//vdText object with setDocumentDefaults has the STANDARD TextStyle.
//
We will change the font of this textstyle to Verdana.
vdFC.BaseControl.ActiveDocument.TextStyles.Standard.FontFile = "Verdana";//We set the insertion point depending the width of the Text from thevdFigure's BoundingBox
onetext.InsertionPoint = new VectorDraw.Geometry.gPoint(40.0 onetext.BoundingBox.Width, 2);onetext.TextLine = VectorDraw.Render.grTextStyleExtra.TextLineFlags.OverLine;//Now we will add this object to the Entities collection of the Model
Layout(ActiveLayout).
vdFC.BaseControl.ActiveDocument.ActiveLayOut.Entities.AddItem(onetext);//Zoom in order to see the object.
vdFC.BaseControl.ActiveDocument.ActiveLayOut.ZoomWindow(newVectorDraw.Geometry.gPoint(-30.0, -10.0), new VectorDraw.Geometry.gPoint(80.0,50.0));//Redraw the document to see the above changes.
vdFC.BaseControl.ActiveDocument.Redraw(true);}
You can also create a MultiLine Text with code like below:

private void butMtext_Click(object sender, EventArgs e){//We will create a vdMText object and add it to the Active Layout which is thebasic//
Model Layout always existing in a Document.

VectorDraw.Professional.vdFigures.vdMText onemtext = new
VectorDraw.Professional.vdFigures.vdMText();//We set the document where the Mtext is going to be added. This is important// for the vdMText in order to obtain initial properties with
setDocumentDefaults.
onemtext.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
onemtext.setDocumentDefaults();//Now we will change some properties of the text.
onemtext.InsertionPoint = new VectorDraw.Geometry.gPoint(20, -15);
onemtext.HorJustify =VectorDraw.Professional.Constants.VdConstHorJust.VdTextHorCenter;onemtext.BoxWidth = 45;//The Text string can contain some special control characters like "\P" or"\C1" which//
control the way that this multiLine text is going to be displayed.

50.0d));//Redraw the document to see the above changes.
vdFC.BaseControl.ActiveDocument.Redraw(true);}
The code above will have a result like :In the Text String some special control characters/strings can be used in order to change the appearence of the text.
These are :\0...\oTurns overline on and off\L...\lTurns underline on and off\\

Getting Started - Object Snaps (OSnaps) - vdFramedControl
Object options allow you to draw in the Object Snap (OSnap). An OSnap mode specifies a snap point at an exact location on an object (like the mid-point of a line).
The OSnap mode helps the user to draw an object in a position relative to a previously drawn object.
The snap point on an object can be; End-point, Mid-point, Center point, Insertion point, Perpendicular, Nearest, Apparent Intersection, Node (point), Quadrant,
Tangent and Intersection.
The OSnap mode remains active until you turn it off, and there is an OSnap indicator in status bar if you choose to set it visible.
You can create a simple project, a form with a vdFramedControl and a button and open adrawing that contains some enities like lines, points inserts etc. Then in the
button click code you can set the OSnaps to Mid point plus Center point and start a user command like cmdLine that will ask the use to give the line's points withmouse :

vdFC.BaseControl.ActiveDocument.osnapMode = VectorDraw.Geometry.OsnapMode.CEN;
vdFC.BaseControl.ActiveDocument.osnapMode |= VectorDraw.Geometry.OsnapMode.MID;
vdFC.BaseControl.ActiveDocument.CommandAction.CmdLine("USER");The code above will highlight the end points and center points while the cmdLine is active:

Getting Started - Section Clipping - vdFramedControl
VectorDraw uses section clipping planes to hide an area of the drawing. This SectionClip defines the side of the drawing that will be visible.
The rest will be hidden and this applies to the Render mode. The visible plane is defined in the vdSectionClip object by defining theOriginPoint and the Direction vector. The direction of that vector defines the visible area. The area in the opposite direction will be hidden.
Direction with the OriginPoint define the plane that will do the section clipping. Their values are always in World Coordinating System.
Multiple vdSectionClip objects will show the common viewable area of all. This allows an unobstructed interior view of a 3D drawing byhiding the defined area from view.

Below is a sample code that will draw a sphere and will add two section clips :

private void TestClippingSections(){
vdFC.BaseControl.ActiveDocument.New(); // We create a new document//We change the active pen color so the created (and added to the document by the cmdSpherefunction) spheres will take this color.
vdFC.BaseControl.ActiveDocument.ActivePenColor.ColorIndex = 9;
vdFC.BaseControl.ActiveDocument.CommandAction.CmdSphere(new VectorDraw.Geometry.gPoint(5, 5),
2.0, 40, 40);//Zoom in order to see the object.
vdFC.BaseControl.ActiveDocument.ActiveLayOut.ZoomAll();
vdFC.BaseControl.ActiveDocument.CommandAction.View3D("RENDER");//Redraw the document to see the above changes.
vdFC.BaseControl.ActiveDocument.Redraw(true);MessageBox.Show("Sphere created and is shown in RENDER mode.\r\n We will create a clip (center ofthe sphere) to hide the left half of the sphere.");//We will create a clip (center of the sphere) to hide the left half of the sphere.

clip.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
clip.Name = "SLICE1";
clip.Enable = true;clip.OriginPoint = new VectorDraw.Geometry.gPoint(5.0, 5.0, 0);clip.Direction = new VectorDraw.Geometry.Vector(1, 0, 0); //This is the direction where we want
the visible objects to be.
vdFC.BaseControl.ActiveDocument.ActiveLayOut.Sections.AddItem(clip);
vdFC.BaseControl.Redraw();//We create another clip that will hide the bottom half of the sphere.
MessageBox.Show("Now we will create a second clip to hide the bottom half of the sphere.");clip = new VectorDraw.Professional.vdObjects.vdSectionClip();

Getting Started - Selections - vdFramedControl
The Selections objects (vdSelection) can be used in order to temporary (not saved in the drawing) create agroup of drawing objects (like lines, circles etc) in order to apply properties (like pencolor) or to transformthem (like using cmdMove):1) A simple code:

private void butGetSelection_Click(object sender, EventArgs e){
vd.BaseControl.ActiveDocument.New();
AddSomeEntities(); // This function adds some entities like lines and cirlces
vd.BaseControl.ActiveDocument.Prompt("Select Entities:");vdSelection selset = vd.BaseControl.ActiveDocument.ActionUtility.getUserSelection();vd.BaseControl.ActiveDocument.Prompt(null);if (selset != null) {MessageBox.Show("You have selected " + selset.Count + " figures");
foreach (vdFigure var in selset)
var.HighLight = true;
vd.BaseControl.ActiveDocument.Redraw(true);}}

The code above starts an new empty document, call a function to create some entities, and prompts the user
to select some entities by choosing a window. If there are entities selected then displays the number of themand set the HighLight property of each of them to true.

2) If we want to move (transform the location of) the entites that are selected then the code can be :private void butGetSelection_Click(object sender, EventArgs e){
vd.BaseControl.ActiveDocument.New();
AddSomeEntities(); // This function adds some entities like lines and cirlces
vd.BaseControl.ActiveDocument.Prompt("Select Entities:");vdSelection selset = vd.BaseControl.ActiveDocument.ActionUtility.getUserSelection();vd.BaseControl.ActiveDocument.Prompt(null);if (selset != null) {gPoint pt1 = new gPoint(0, 0, 0);gPoint pt2 = new gPoint(2, 2, 0);
vd.BaseControl.ActiveDocument.CommandAction.CmdMove(selset, pt1 , pt2);
vd.BaseControl.ActiveDocument.Redraw(true);}}
The code above will move the selected entities from point {0,0,0} to point {2,2,0}.

Getting Started - SupportPath - vdFramedControl
SupportPath is a very useful property of the VectorDraw Developers Framework. This property specifies the
directories in which VDF searches for files when using methods for drawings like insert, file open, images and
XRef (External Reference) attach, SHX font files. It is a string with multi paths separated by semicolon < ; >like:
c:\;c:\temp;c:\Program Files/VectorDraw;
The order when VectorDraw searches is :1) The folder that drawing is placed.
2) The Support path.

You can get/set the support path property like :// adds the c:\temp folder to the SupportPath property
string SupPath;SupPath = vdFC.BaseControl.ActiveDocument.SupportPath;// Get
SupPath = SupPath + @"c:\temp;";vdFC.BaseControl.ActiveDocument.SupportPath = SupPath;// Set

The ToolTips is a property that applies to vdFigures, it is used to display a text when the mouse is over this object if
EnableToolTips property of vdDocument is true. Like :The tooltip can be a multi line text like in the above example that "\n" is used to break the text to 2 lines.
You can change the way that the tooltips appear using the properties that you can find under the in"ToolTipDisplayProps Class, Members" topic of our help. Like:

Beside tooltips you can use URLs that can be used in order to guide the user to an external link like a website. URLs
apply to an vdFigure if this object has an non-empty URL property and also the EnableUrls Property is true. For
example you can set the URL property of a vdFigure to "http://www.vdraw.com" in order to open this web page
when the user clicks (holding down CTRL keyboard key) this figure. If CTRL keyboard key is not down then the web
page will not open.

Getting Started - Undo & Redo - vdFramedControl
The VectorDraw Developer Framework has Undo and Redo functionality which is unlimited. You can undo thelast actions one by one or group them and undo the whole group. The same is for redo previously undo
actions. A simple code will be like adding an entity (using for example cmdCircle) and undo the last action.
Like :

private void Button_cmdCircle(object sender, EventArgs e){ //This will draw one user-defined (center point and radius) circle. This
code must be run before the UNDO code
vdFC.BaseControl.ActiveDocument.CommandAction.CmdCircle(null, null);}
private void button_Undo(object sender, EventArgs e){ //This will Undo the last action if exists. cmdCircle code must run before
this.
vdFC.BaseControl.ActiveDocument.CommandAction.Undo("");}
After the Button_cmdCircle code run and the button_Undo run then the Redo can run and bring back thecircle, like :private void button_Redo(object sender, EventArgs e){ //This will REDO the last action if exists
vdFC.BaseControl.ActiveDocument.CommandAction.Redo();}Except this simple undo/redo calls, you can also group some code so this can be undo/redo as a group. See
the code below :private void Button_Circles(object sender, EventArgs e){ //This will draw 4 circles inside a undo Group
vdFC.BaseControl.ActiveDocument.CommandAction.Undo("BEGIN"); //The UndoGroup begins
VectorDraw.Geometry.gPoint pt = new VectorDraw.Geometry.gPoint(1.0d,
1.0d, 0.0d);
vdFC.BaseControl.ActiveDocument.CommandAction.CmdCircle(pt, 0.4d);
pt.x = 2.0d; pt.y = 2.0d;
vdFC.BaseControl.ActiveDocument.CommandAction.CmdCircle(pt, 0.4d);
pt.x = 3.0d; pt.y = 3.0d;
vdFC.BaseControl.ActiveDocument.CommandAction.CmdCircle(pt, 0.4d);
pt.x = 4.0d; pt.y = 4.0d;
vdFC.BaseControl.ActiveDocument.CommandAction.CmdCircle(pt, 0.4d);
vdFC.BaseControl.ActiveDocument.CommandAction.Undo("END");//The UndoGroup ends here}
After this code run, 4 circles will be created. One undo call and these 4 circles will disappear like they were
never drawn. After this undo, one Redo will bring back thes four circles.

Beside this, you can also clear the undo & redo history, and after that previous undo/redo actions will not be
available. You can do this using a code like :private void button_ClearUndo(object sender, EventArgs e){ //This will Clear the Undo & Redo history. No Undo/redo will be available
from this point
vdFC.BaseControl.ActiveDocument.ActiveLayOut.UndoHistory.Clear();}You can also get the undo & redo actions count using a code like:private void button_GetURCount(object sender, EventArgs e){ //This will write to a textbox the undo/redo that are available
textBox1.Text = " Undo : " +vdFC.BaseControl.ActiveDocument.UndoHistory.UndoStackLength.ToString() + "Redo : " +vdFC.BaseControl.ActiveDocument.UndoHistory.RedoStackLength.ToString();}

Getting Started - Units (Linear - Angle) - vdFramedControl
Coordinates are being expressed in drawing units (D.U.). Drawing units are not expressing particular units (meters, inches etc). In this partuser have to make some assumptions in order to define that the coordinates of the drawing mean particular units (meters, inches etc).
For example: For a mechanical drawing we can make the assumption for example: where one drawing unit defines one millimeter(1 D.U.
=1mm). For a architectural/technical drawing we can make the assumption for example: where one drawing unit defines one meter(1 D.U.
=1m). This can be very helpful in designing, dimensioning, retrieving information from the drawing (distances, area calculations etc)
You can specify the type of the current unit of measurement (linear and angle) and the precision for the current units as also the current angle
format and the precision for the current angle display. The type of measurement can be:Linear LUNITS
Scientific like 1.6449E+001 lu_Scientific = 1
Decimal like 16.4492
lu_Decimal = 2
Engineering like 1' - 4.4492" lu_Engineering = 3
Architectural like 1' - 4 7/16" lu_Architectural = 4
Fractional like 16 7/16
lu_Fractional = 5
Windows desktop (It takes thesettings of the regional
lu_windesk = 6
settings)

Angle AUNITS
Decimal degrees
Degrees/minutes/seconds
GradiansRadians
Surveyor

These Properties change only the display and not the values which are in Drawing Units.
Running a code like :private void button1_Click(object sender, EventArgs e){
vdFC.BaseControl.ActiveDocument.ActiveLayOut.lunits.UType =VectorDraw.Geometry.LUnits.LUnitType.lu_Architectural;
vdFC.BaseControl.ActiveDocument.ActiveLayOut.aunits.UType =VectorDraw.Geometry.AUnits.AUnitType.au_Radians;}
You will get a display like :The Angular & Linear units also apply to the vdDimensions and Dimension Styles. See the following code :au_Decdegrees = 0
au_Degrees = 1
au_Gradians = 2
au_Radians = 3
au_Surveyor = 4

private void button2_Click(object sender, EventArgs e){
vdFC.BaseControl.ActiveDocument.New();

Getting Started - XProperties - vdFramedControl
The XProperties are used to store extended data in a object. For example you might add the part number asa string in a vdInsert object that represents graphically the part. This can be connected to a database withmore information for this object.
For example if you like the user to input a point in the drawing the you can call a code like ://We will add a circle (assume that the circle represents a part) to themodel with a xproperty in it's collection that will represent the part number
in our database.
VectorDraw.Professional.vdFigures.vdCircle circle = new
VectorDraw.Professional.vdFigures.vdCircle();circle.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
circle.setDocumentDefaults();
circle.Radius = 5.0;
circle.Center = new VectorDraw.Geometry.gPoint(2, 2, 0);//Add string value xproperty that will represent in our applicatio the partnumber of this part.
VectorDraw.Professional.vdObjects.vdXProperty xprop = new
VectorDraw.Professional.vdObjects.vdXProperty();xprop.Name = "Part No.";
xprop.PropValue = "FG 127-34566";
circle.XProperties.AddItem(xprop);
vdFC.BaseControl.ActiveDocument.Model.Entities.AddItem(circle);
vdFC.BaseControl.ActiveDocument.Redraw(true);
You can also see topic "vdLinetype Class" in our VDF help (VDF.CHM).
The XProperties can also be stored in other objects than graphical entities. The objects can be vdLayouts,
vdLayers etc.

There are also some Xproperties that are dynamic and are binded to the geometrical information of theobjects. For example you can have the length of the line binded to the line and when this line is stretched orscaled the value of the XProperty is changed accordingly. See the code below:

VectorDraw.Professional.vdObjects.vdXProperty xprop = new
VectorDraw.Professional.vdObjects.vdXProperty();
VectorDraw.Professional.vdFigures.vdLine line = new
VectorDraw.Professional.vdFigures.vdLine();line.SetUnRegisterDocument(vdFC.BaseControl.ActiveDocument);
line.setDocumentDefaults();line.StartPoint = new VectorDraw.Geometry.gPoint(0, 0, 0);line.EndPoint = new VectorDraw.Geometry.gPoint(2, 2, 0);xprop.Name = "ThisLineLength";xprop.PropValue = line.EndPoint.Distance3D(line.StartPoint);
xprop.TransformID =VectorDraw.Professional.vdObjects.vdXProperty.TransformationType.WorldSpaceDist;line.XProperties.AddItem(xprop);

Getting Started - External Reference (Xrefs) - vdFramedControl
External Reference files (XRefs) are drawings that can be attached for reference in a drawing. When you
attach a drawing as an xref, you link that referenced drawing to the current drawing; any changes to thereferenced drawing are displayed in the current drawing when it is opened or reloaded. A drawing can be
attached as an XRefs to multiple drawings at the same time and multiple drawings can be attached as
referenced drawings to a single drawing.
Note that the objects in the XRefs attached to the current drawing are model space objects only. You caninsert the xref into the current drawing in either model space or paper space. The XRefs can be attached at
any location, scale, and rotation. The XRefs is a vdBlock object that is inserted (instance) in the drawing as a
vdInsert object.
Below is a sample code that will add an existing drwaing as an XRef file. This should be defined as a vbBlockwith ExternalReferencePath property :private void AddExternalReferences(){//We will add a vdblock object as an external reference to the blocks dialog.
string path = Application.ExecutablePath.Substring(0,Application.ExecutablePath.LastIndexOf('\\')) + "\\..\\..\\wmap.vdml";//thename and path of the file that will be added as XRef
VectorDraw.Professional.vdPrimaries.vdBlock xref = new

xref.setDocumentDefaults();
xref.Name = "wmap";
xref.ExternalReferencePath = path;//With update the file is opened and the document of the file is added to
the External references of the file.
xref.Update();vdFC.BaseControl.ActiveDocument.Blocks.AddItem(xref);}After this the XRef (vdBlock) should be inserted in the drawing. See the sample code below :private void AddReferencesInserts() {//Now we will add the vdinsert object that will show the externalreference that we created.
VectorDraw.Professional.vdFigures.vdInsert ins = new
VectorDraw.Professional.vdFigures.vdInsert();ins.SetUnRegisterDocument(vdFramedControl1.BaseControl.ActiveDocument);
ins.setDocumentDefaults();//We check if the block exists and then give it to the insert.
VectorDraw.Professional.vdPrimaries.vdBlock blk =vdFC.BaseControl.ActiveDocument.Blocks.FindName("wmap");
if (blk != null){ins.Block = blk;
vdFC.BaseControl.ActiveDocument.Model.Entities.AddItem(ins);}//Note that the Same operation like above could have been done with thefollowing function cmdXref.
