- PRP PT allows you to create a line perpendicular to
- a selected entity, and through a specified point.
-
- Select the desired entity, near the point of
- perpendicularity.
-
- Indicate the reference point that the perpendicular line
- will pass through, using a Position Menu option.
-
- An error message is displayed if you are constructing in
- 3-D and the entities you select are not coplanar. You are
- prompted to press <Enter> and to select the first entity.
-
- If the reference point is on the selected entity and the
- L-LIMIT switch is set to FUNCTN, an error message is
- displayed indicating that the current settings and
- selections result in a zero-length line. If this message
- is displayed, change the line limits, and press <Enter>,
- or reselect the desired entity and reference point.
-
- With the L-LIMIT switch set to FUNCTN, the perpendicular
- line is created with the reference point and the
- perpendicularity point as its endpoints.
-
- If the reference point is on the selected entity and the
- L-LIMIT switch is set to VIEWPORT, the line is
- perpendicular to the selected entity at the specified
- reference point, and the line extends to the screen
- limits.
