CHAPTER 1 The Basics of auTocaD civil 3D

Where Is Delta?

In the Text Component Editor for a curve label, the value that most people would refer to as a delta

angle is called the General Segment Total Angle. To insert the Delta symbol in a label, type \U+0394

in the Text Editor window on the right side of the Text Component Editor dialog.

7. At the Select Entity: prompt, select each line and arc that you drew in the previous

exercise. A label appears on each entity at its midpoint, as shown in Figure 1.49.

8. Save the drawing—you’ll need it for the next exercise.

Using Transparent Commands

In many cases, the “Create Line By…” commands in the Draw panel are the standard AutoCAD

Line commands combined with the appropriate transparent commands.

A transparent command behaves somewhat similarly to an osnap command. You can’t click

the Endpoint button and expect anything to happen—you must be active inside another com-

mand, such as a line, an arc, or a circle command.

The same principle works for transparent commands. Once you’re active in the Line com-

mand (or any AutoCAD or Civil 3D drawing command), you can choose the Bearing Distance

transparent command and complete your drawing task using a bearing and distance.

As stated earlier, the transparent commands can be used in any AutoCAD or Civil 3D draw-

ing command, much like an osnap. For example, you can be actively drawing an alignment and

use the Northing/Easting transparent command to snap to a particular coordinate, and then

press Esc once and continue drawing your alignment as usual.

While a transparent command is active, you can press Esc once to leave the transparent mode

but stay active in your current command. You can then choose another transparent command

if you’d like. For example, you can start a line using the Endpoint osnap, activate the Angle
