Introduction
Although Draw does not match the functionality of leading drawing or image editing programs, it
is capable of producing and editing 3D drawings. In Draw, two types of 3D objects are available:
3D scenes and extruded 3D shapes. The Status Bar indicates when a 3D scene has been
selected (Figure 1), but only indicates a shape has been selected (Figure 2) when an extruded
3D shape is selected.
Depending on which type is selected, there are different possibilities for further editing of theobject (rotation, illumination, perspective, and so on). Extruded 3D shapes are simpler to set up
and edit, but 3D scenes allow for greater customization.
3D objects are created using one of the following methods:• 3D Objects — these are ready made 3D objects and are also 3D scenes. They are
selected using one of the following methods:– Click on 3D Objects in the Drawing toolbar (Figure 3).
– Select a 3D object in the 3D Objects panel in the Shapes deck on the Sidebar(Figure 4).
• Convert a 2D object into a 3D object use one of the following tools. The tools areavailable on the Drawing toolbar (highlighted in Figure 3), by right-clicking on the object
and selecting from the context menu, or the 3D Effects dialog:– To 3D — creates a 3D scene containing an extrusion object.
– To 3D Rotation Object — creates a 3D scene using a default rotation axis.
– Toggle Extrusion — creates a 3D shape by extruding a 2D object into 3D. Only 3D
shapes that have been extruded can be converted back to a 2D object.
– Convert To Rotation Object — available in the 3D Effects dialog. Converts a
selected 2D object into a 3D rotation object. Also, selecting several ungrouped 2D
objects can be converted into a single 3D rotation object.

Notes
Before creating 3D objects in a drawing, it is recommended that the extra 3D
tools (To 3D; To 3D Rotation Object; Toggle Extrusion) are added to the
Drawing toolbar using Visible Buttons or the Customize dialog. For more
information on using Visible Buttons and the Customize dialog, see Appendix B,
Toolbars and the Getting Started Guide.
After installing the 3D tools onto the Drawing toolbar, the tools only become
available for use when a 2D object is selected in a drawing.

3D object types
3D scenes
3D scenes are created from objects with dimensions using x, y, and z coordinates and cancontain object types, such as cube, sphere, extrusion object or rotation object. These object
types do not exist outside a 3D scene.
The Status Bar displays 3D scene selected when a 3D object is selected that has been createdfrom a 2D object using body rotation or conversion, or it is a ready-made 3D object that has been
inserted into a drawing.
A 3D scene is similar to a group. Just like a group, a 3D scene can be entered for editing an
individual object in the 3D scene and then exit after editing is completed. See Chapter 5,
Combining Multiple Objects for more information on entering, editing and exiting groups.
When a 3D scene is created from a selection of more than one 2D object, a group is
automatically created as a single 3D scene. This 3D scene can be entered so that individual
objects within the 3D scene can be changed, edited and rotated.

3D object types | 5

Note
Individual objects cannot be ungrouped when a 3D scene has been created froma selection of 2D objects.

3D shapes
2D shapes are flat with only width and height dimensions, but 3D shapes are solid objects thathave three dimensions: depth, width, and height.
A 3D shape is created when a 2D shape or an object from the Fontwork Gallery is turned into 3D
using Toggle Extrusion. The Status Bar displays Shape selected when this type of 3D object isselected.
A 3D shape can be viewed and edited in 3D or 2D mode. To edit in 2D mode, switch off
extrusion, make the editing changes, and switch back to 3D mode using Toggle Extrusion.

Note
Toggle Extrusion can only be used when a 2D shape, a 3D object that has been
extruded from a 2D shape, or an object from the Fontwork Gallery is selected in a
drawing. It is not available for text, lines, arrows, curves, and polygons.

Creating 3D objects
3D ready made objects
3D ready made objects are 3D scenes and are inserted into a drawing using one of the following
methods. The selection and drawing of 3D objects is the same for all methods of inserting a 3D
ready made object.
• Click on the triangle ▼ to the right of 3D Objects on the Drawing toolbar and select a 3D
object from the sub-toolbar that opens. The 3D Objects icon displayed on the Drawing
toolbar depends on the 3D object that had been previously selected and used.
• Go to View > Toolbars > 3D-Objects on the Menu bar to open the 3D-Objects toolbar(Figure 5). This toolbar has the same options available as the 3D Objects tool on the
Drawing toolbar.
• Go to Shapes > Insert > 3D Objects on the Menu bar and select a 3D object from thesubmenu.
• Go to the 3D Objects panel in the Shapes deck on the Sidebar and select a 3D object.

Note
Ready made 3D objects can be repositioned, resized, and edited in the same way
as 2D objects. See Chapter 3, Working with Objects for more information.

Figure 6: Example of 3D conversion using extrusion

Figure 7: Example of 3D conversion using rotation

Extrusion
Extrusion converts a 2D object into a 3D scene by extruding the 2D object toward the observer.
The scene is rotated by 20 degrees around the horizontal axis to make the 3D effect more
visible. Examples of 3D conversion using extrusion are shown in Figure 6. After selecting a 2D
object, convert it to a 3D scene using one of the following methods:• Right-click on the 2D object and select Convert > To 3D from the context menu.
• Click on To 3D in the Drawing toolbar.
• Go to Shape > Convert > To 3D on the Menu bar.
• Click on Convert to 3D in the 3D Effects dialog. For more information see “3D effects” onpage 10.

Rotation
To 3D Rotation Object or Convert to Rotation Object converts a 2D object into a 3D scene byrotating the object using the left edge of the bounding box around the object as the axis ofrotation. Examples of 3D conversion using either of these rotation tools are shown in Figure 7.
The actual 3D scene created depends on the angle and shape of the object being rotated.

Creating 3D objects | 7

After selecting a 2D object in a drawing, convert it to a 3D scene using rotation with one of thefollowing methods:• Right-click on a 2D object and select Convert > To 3D Rotation Object from the context
menu.
• Click on To 3D Rotation Object in the Drawing toolbar.
• Go to Shape > Convert > To 3D Rotation Object on the Menu bar.
• Click on Convert To Rotation Object in the 3D Effects dialog. For more information see“3D effects” on page 10.

Toggle Extrusion
Extrusion is where parallel surfaces are moved to create a 3D shape. In Draw, the 2D surface is
moved forwards out of the drawing level. At the same time the object is slightly tilted and central
projection turned on, creating the impression of a 3D shape. Draw uses a default value for thisextrusion (body depth) based on the size of the 2D object. The value can be changed after the
extrusion, see “Editing 3D objects” on page 9.
Extrusion conversion is carried out using Toggle Extrusion. Extrusion only works on Basic
Shapes, Symbol Shapes, Block Arrows, Flowcharts, Callouts, Stars and Banners, and Fontworkthat are included as a part of the default set of tools on the Drawing toolbar or in the Shapes deckon the Sidebar. Examples of toggle extrusion are shown in Figure 8.
1) Select a 2D object in a drawing that has been created from Basic Shapes, Symbol
Shapes, Block Arrows, Flowcharts, Callouts, Stars and Banners, or Fontwork.
2) Click on Toggle Extrusion on the Drawing toolbar to convert the 2D object into a 3D
shape.
3) To convert a 3D conversion back into a 2D object, select the 3D object and click on
Toggle Extrusion on the Drawing toolbar.

Note
Extrusion cannot be used on text objects created using Insert Text Box or Insert
Vertical Text.

Editing 3D objects
Note
Where 3D scenes have been created from more than one 2D object, a 3D scene
group is automatically created. This 3D scene group cannot be ungrouped andany editing carried out will affect all 3D objects within the group. To edit anindividual 3D object within this 3D scene group, enter the group. For more
information on working with groups, see Chapter 5, Combining Multiple Objects.

Position, Size and Rotation
Editing the position, size and rotation of 3D objects is similar to 2D objects. See Chapter 3,
Working with Objects for more information.

3D settings
To open the 3D-Settings toolbar (Figure 9), go to View > Toolbars > 3D-Settings on the Menu
bar. The 3D-Settings toolbar only becomes active when a 3D shape is selected that has beencreated from a 2D object using “Toggle Extrusion” on page 8.
The result of any changes made using the editing tools on the 3D-Settings toolbar is applied tothe selected 3D shape immediately displaying the effect of the 3D setting applied. Figure 10
shows an example of tilting left, increasing extrusion depth, and changing 3D color using the
3D-Settings toolbar.
The tools available for editing 3D shapes are as follows.
Tilt Down
Tilts the selected object downward (horizontal axis rotation) by 5 degrees each time theicon is used.

Figure 9: 3D-Settings toolbar

Figure 10: Example of changing 3D settings

Editing 3D objects | 9

Tilt Up
Tilts the selected object upward (horizontal axis rotation) by 5 degrees each time the icon
is used.
Tilt Left
Tilts the selected object left (vertical axis rotation) by 5 degrees each time the icon is
used.
Tilt Right
Tilts the selected object right (vertical axis rotation) by 5 degrees each time the icon is
used.
Depth
Opens a pop-up menu where the extrusion depth can be set from an object by a fixed orcustom amount.
Direction
Opens a pop-up menu where the view direction can be set to create an extrusion in either
a perspective or parallel projection.
Lighting
Opens a pop-up menu where the direction and intensity of the lighting can be set whencreating an extrusion.
Surface
Opens a pop-up menu where the surfaces of the object can be set as Wire Frame, Matt,
Plastic, or Metal display.
3D Color
Opens a pop-up menu where the color used for the extrusion can be set. This color does
not have to be the same as the color used for the original 2D object.

3D effects
The 3D Effects dialog (Figure 11) offers a wide range of possible settings for editing 3D readymade objects or 3D scenes. This dialog can also be used to convert a 2D object to 3D using thetools in the bottom left corner of the dialog.
To open the 3D Effects dialog, click on 3D Effects on the Line and Filling toolbar, or go toFormat > 3D-Effects on the Menu bar. Any 3D effects applied to a 3D scene are not carried out
until Assign is clicked in the top right of the 3D Effects dialog. This allows for all 3D effectchanges to be carried out before applying them to a 3D scene.

Notes
The 3D Effects dialog cannot be used on 3D shapes created using Toggle
Extrusion because the correct formatting results will not be achieved. If the 3D
Effects dialog is used in error, remove any incorrect formatting by going toFormat > Default Formatting on the Menu bar.
Any options on the pages in the 3D Effects dialog that are grayed out cannot be
used for the selected object.

3D conversion
In the bottom left corner of the 3D Effects dialog are tools for converting a 2D object into a 3D
scene and changing the projection used in a 3D scene.
Convert to 3D
Converts the selected object into a 3D scene. This tool works in the same way as using“Extrusion” on page 7.
10 | Chapter 7, Working with 3D Objects

Figure 11: 3D-Effects dialog — Geometry page
Convert to Rotation Object
Converts a 2D object into a 3D scene using body rotation. This tool works in the same
way as using “Rotation” on page 7.
Perspective On/Off
Switches perspective projection on or off for a 3D scene. Perspective projection is atechnique to create a linear illusion of depth. As objects get further away from the viewer,a perspective drawing decreases in size at a constant rate.

Note
The 3D Effects dialog has five pages to provide options for Geometry, Shading,Illumination, Textures, and Material. The tools to change pages for the different
types of 3D effects are located at the top of the 3D Effects dialog.

3D Effects — Geometry
Click on Geometry in the 3D Effects dialog (Figure 11) to open the Geometry page and use theoptions available to change the geometry of a 3D object.
Geometry
Defines the properties of an object in a 3D scene.

3D Rotation Object. Figure 14 shows an example of a 2D circle where the rotation
angle is changed to 180 degrees.
DepthEnter the extrusion depth for the selected 2D object that has been converted to 3D
using To 3D. Figure 15 shows an example of a 2D circle converted to a 3D cylinder withthe extrusion depth increased to 3 cm.

Segments
Changes the number of segments that Draw uses to draw a 3D rotation object. The
higher the number of segments, the smoother the object surface will be. However, a highsegment number may increase the time it takes to generate the 3D object on a display.
Figure 16 shows the difference on a 3D sphere when the segments have been increased
from 10 to 30 segments horizontally and vertically.
Horizontal
Enter the number of horizontal segments used in the selected 3D rotation object.
VerticalEnter the number of vertical segments used in the selected 3D rotation object.

3)

Spherical

Flat
Renders the 3D surface as polygons (Figure 17).
Spherical
Renders a smooth 3D surface regardless of the shape of the object (Figure 17).
Invert Normals
Inverted normal is a normal that is pointing in the wrong direction (Figure 18). This tells
a computer that an outside face is actually an inside face when it is not. If there is ahollow design, an inverted normal can be indicated because both surfaces facing are in
and out in the same model.
Double-Sided Illumination
Lights the outside and the inside of the object (Figure 18). This has only an effect, if theinside is drawn at all, see Double-Sided. This is a setting for the whole of the 3D scene
and not for a single object within the scene.
Double-Sided
3D object has outside (front) and inside (back) faces (Figure 18). With Double-Sidedswitched off, only the outside face of the object is rendered. The effect, when looking
from outside, is that the object is solid, but, when looking from inside, the front face istransparent. If there is no view to the inside face, normal for an extruded 3D object withsolid texture, Double-Sided should be switched off to improve performance during
rendering. Any 3D object created using rotation often allows an inside view and it isrecommended that Double-Sided is switched on.

Note
Figure 18 demonstrates the 3D effect of using Invert Normals in conjunction withusing the 3D effect Double-Sided Illumination.

3D Effects — Shading
On the Shading page of the 3D Effects dialog (Figure 19) provides options to set the shading,shadow, and camera effects on a selected 3D object.
ShadingSpecifies the mode of shading applied to a 3D object (Figure 20).

Editing 3D objects | 15

Gouraud
This shading mode is a method used in computer graphics to simulate the differing
effects of light and color across the surface of an object. In practice, it is used toachieve smooth lighting on low-polygon surfaces without the heavy computational
requirements of calculating lighting for each pixel.
PhongThis shading mode is an interpolation technique for surface shading calculating thenormal of a point in the polygon by interpolating the normals of the vertices. The angle
between normal and lighting direction determines how much of the lighting is used tocolor the pixel.
Flat
This shading mode refers to the depiction of depth perception in 3D models or
illustrations by varying the level of darkness. It assigns a single color of shading to asingle segment on the surface of the object.
Shadow
Adds or removes a shadow from a selected 3D object (Figure 21). A shadow is generated
only from the first light source. Enter a Surface Angle from the light source to the surface
between 0 to 90 degrees to cast a shadow.

CameraSets the camera options for a selected 3D scene as if a camera is being used to take aphotograph (Figure 22). The settings affect only central perspective and not parallel
projection.
DistanceEnter the distance to leave between the camera and the center of the selected 3D
scene. The default setting for distance is 2.6cm.
Focal length
Enter the focal length of the camera lens, where a small value corresponds to a fisheyelens and a large value to a telephoto lens. The default setting for focal length is 10cm.

3D Effects — Illumination
The Illumination page of the 3D Effects dialog (Figure 23) defines how a 3D scene is lit and thesettings apply to all 3D objects in a scene. The direction of the light source, color of the lightsource, and the ambient light can be specified for the 3D scene.
By default, one light source is already selected when the Illumination page is opened. More lightsources can be selected for illumination. A maximum of eight sources can be used and each lightsource can use a different color.

Figure 23: 3D Effects dialog — Illumination page

3D Effects — Material
On the Materials page of the 3D Effects dialog (Figure 25) the appearance of a 3D object can bechanged to represent different materials. Materials and Textures can be combined with eachother and it is a matter of trial and error to achieve the desired result.
Material
Assigns a color from a color palette. For custom colors, see Chapter 11, Advanced Draw
Techniques for more information on creating custom colors.
Favorites
Select a material type for the selected object from the Favorites drop-down list.
Object color
Select a color from one of the color palettes in the Object color drop-down list to apply
to the object.
Illumination color

Specular
Sets the light reflection properties for the selected object simulating the reflecting capacityof the surface. The position of the illuminated point is determined by the setting of the firstlight source.
Color
Select a color to be reflected from the object from one of the color palettes in the Color
drop-down list.
Intensity
Enter the intensity of the specular effect as a percentage.
Colors Dialog
Opens the Pick a Color dialog where custom colors are defined using the 2D graphic andnumerical gradient chart. Any colors created are stored in the custom palette. See
Chapter 11, Advanced Draw Techniques for more information on creating custom colors.

Note
Metallic and glass surfaces do not simulate well because the appearance of thesematerials is produced using reflection.

Tip
Do not use a very high brightness value for individual colors. Colors are additiveand it is easy to end up with a colored area that is white.

Combining objects
Multiple 3D objects cannot be combined using Shape > Combine on the Menu bar or the
keyboard shortcut Ctrl+Shift+K (macOS ⌘+Shift+K). Multiple 2D objects have to becreated first, then a single 3D object created as follows (see Chapter 5, Combining Multiple
Objects for more information on combining objects):
1) Create multiple 2D objects and carry out all the necessary editing changes.
2) Make sure that all 2D objects are selected to create a single 3D object.
3) Create a single 3D object combining the multiple 2D objects using one of the following
methods (examples of 3D objects are shown in Figure 26):
– Click on To 3D or To 3D Rotation Object on the Drawing toolbar.
– Right-click on the selected multiple 2D objects and select Convert > To 3D or To 3D
Rotation Object from the context menu.
– Go to Shape > Convert > To 3D or To 3D Rotation Object on the Menu bar.

Assembling 3D objects
3D objects that each form a separate 3D scene can be combined or assembled into a single 3D
scene. An example procedure for assembling 3D objects is as follows and shown in Figure 27:1) Select a 3D object (for example, a cube) from 3D Objects on the Drawing toolbar, orShapes deck on the Sidebar and place it in a drawing.
2) Select a second 3D object (for example, a sphere) from 3D Objects on the Drawing
toolbar, or Shapes deck on the Sidebar and place it in the drawing.
3) If necessary, set the area fill to None and the lines to Continuous to create wire frame
objects. This makes it easier to position both objects in the assembled 3D scene.
