To create a segment at a specific angle, use the Direction command. Direction constrains the angle of the segment to an angular value. For example, if you type 45 as the angle, the segment is constrained to a 45-degree angle one way and a 225-degree angle the other. You can combine Direction with the Length command (Direction/Length) to enter an angle and a length for the next segment.
The Direction type and units are based on the settings on the Units tab of the Editing Options dialog box, accessed from the Editor menu. By default, east is 0 degrees, and positive angles are measured counterclockwise. For example, a 90-degree angle represents north, and a 180-degree angle represents west.
- These steps can be used to create vertices in either lines or polygons:
To create a vertex in a line
Click a line feature template in the Create Features window and click the Line tool .
To create a vertex in a polygon
Click a polygon feature template in the Create Features window and click the Polygon tool .
- Click the Straight Segment construction method on the Editor toolbar.
- Create at least one vertex.
- Right-click away from the sketch and click Direction/Length, or press CTRL+G.
- Type the angle and a length, then press ENTER to constrain the segment to the specified angle.
