CADD NOTE 5

Technical Release 73 provides various standards to use in developing
CADD drawings. The purpose of this CADD Note is to clarify and expand
upon some of the standards in TR-73.

# INSTALLING

To install the files associated with this CADD Note, perform the
following steps. These instructions assume you will be using drive B. If
drive A is used, substitute A for all references to B.

> 1\. Place the CADD Note diskette in drive B.
>
> 2\. From the DOS prompt, enter the following
>
> ***B:INSTALL***
>
> 3\. Answer any prompts that may appear.
>
> 4\. The files should be copied and a message will indicate that
> installation is done.
>
> NOTE: You will need to perform the steps outlined in the sections
> below to utilize the files copied.

# PEN SIZES

The table below defines the size that should be used for pens 1 through
4. The AutoCAD drawing color related to each pen is also shown along
with the intended uses.

If you wish to use a drawing color beyond those listed above, the
following convention should be used:

**AutoCAD colors Convention**

01-89 tens digit is linestyle, ones digit is pen \# (e.g., 23 would use
linestyle 2 with pen 3). Available linestyles (1-8) are seen by
selecting \"Pen Assignments\", \"Feature legend\" from the Plot dialog
box.

90-255 ones digit is pen \#

(e.g., 175 would use pen 5)

# PEN SIZES (cont.)

Included with this CADD note are two files that can be used to update
the pen assignments to match these conventions. One file is for setting
the DraftPro plotter and the other is for the LaserJet 4/IIISi. Follow
the steps below for each plot device to update its pen assignments.

> 1\. Enter **PLOT** at the AutoCAD Command: prompt. The plot dialog box
> should appear.
>
> 2\. Select \"Device and Default Selection\...\".
>
> 3\. Highlight the desired device (e.g., HP DraftPro Plus or LaserJet
> 4/IIISi).
>
> 4\. Select \"Get Defaults From File\...\".
>
> 5\. A file selection dialog box appears. Enter the filename below for
> the device highlighted in step 3.
>
> HP DraftPro Plus: **C:\\ACAD\\DRV\\HPGL2\\SCSDPRO.PCP**
>
> Laserjet 4/IIISi: **C:\\ACAD\\DRV\\HPGL2\\SCSLASR4.PCP**
>
> A message should indicate there were no errors.
>
> 6\. Select \"OK\" to exit \"Device and Default Selection\...\" dialog
> box.
>
> 7\. To check that pen settings were set, select \"Pen Assignments\".
> Select \"OK\" when done checking.
>
> 8\. Press "OK" . At "Press RETURN\..." prompt, press Ctrl-C to cancel
> plotting.
>
> 9\. Repeat steps for the other device.

# LAYERS

Layers allow various drawing features to be separated. The layers shown
in the table below should be used to provide consistency in drawings. In
the case of simple drawings, all of the drawing items may be placed on
AutoCAD\'s 0 layer.

**Layer Name Layer Contents**

AS_BUILT As-built drawing

BORDER Border and permanent title block text

CULTURAL Cultural features (e.g, buildings, wells, etc.)

DIMENSIONS Structural dimensions

DRAW_RECORD Drawing record

FENCES Fence lines

GEOLOGY Geologic features

GRID_BOLD Bold grid lines

GRID_LIGHT Light grid lines

LEGEND Legend for a map or the drawing

MISC Miscellaneous records

MISC_NOTES Miscellaneous notes that you wish not to plot

NOTES Drawing notes

ROADS Roads

STEEL Reinforcing steel with marking and spacing

STR_LINES Structural lines

TITLES User entered text for title block

TREES Trees, brush, etc.

UTILITIES Utilities (e.g., gas or water lines)

WATER Water edge, streams, etc.

Additional layers may be used if a drawing requires more separation than
the above list or if an item is not in the above list.

# LAYERS (Eagle Point)

Eagle Point software creates layers for various features (e.g.,
contours, TINs, profiles, etc.). The default layer names should be used.
When multiple items of a particular feature are desired (e.g., multiple
TIN lines), the default layer name should be appended with text that
further describes the feature. For example, you could use TINORG for
original TIN lines and TINFINAL for final TIN lines.

# TEXT

All text that may be reduced in size should have 0.06 inch minimum
height after reduction. Titles should be all capitals, with 0.09 inch
minimum height after reduction. Table 5.2 below shows small, medium, and
large text sizes to use for the most common sheet sizes used.

It is suggested that only 2 sizes be used on a single drawing; either
small and medium or medium and large depending on the complexity of the
drawing. Dimension text and notes should use the smaller of the two and
title text should use the larger of the two. Arrow sizes should use the
"medium" size listed above in both cases.

When entering a text height in AutoCAD\'s model space, you must enter it
in real world coordinates, not plotted units. For example, if you want
0.06 inch text and you are plotting at a 1\"=100\' scale, you will need
to enter 6 (0.06 x 100) as your text height. Eagle Point\'s settings of
horizontal scale and text size handle the conversion for you when you
use any Eagle Point function that generates text.

The text style used should be consistent throughout the drawing. The
suggested style to use is ROMANS with a 15° oblique angle.

After installing this CADD Note, a program is available to assist you in
setting the appropriate text sizes as well as dimension text and arrow
sizes. It is explained on the following page.

To use it, type the following at the Command: prompt,

> ***SETTEXT***

A dialog box will then appear as shown below.

![](media/image1.emf){width="5.809722222222222in"
height="1.926388888888889in"}

You should then do the following:

> 1\. Select the desired text size for plotted output (small, medium, or
> large).
>
> 2\. Select the sheet size you intend to plot on.
>
> 3\. Enter the horizontal scale.
>
> 4\. Press OK.

The drawing text size is computed (plotted text size x horizontal scale)
and displayed. When you press OK, the text style is set to ROMANS with a
15° oblique angle, text size is set to computed text size, the dimension
scale factor is set to the entered scale, dimension text size is set to
the selected plotted text size, and dimension arrow size is set to the
medium plotted text size.
