Perpendicular Line
The Perpendicular Line tool creates a line passing through a point and perpendicular to a selected
linear object (line, segment, ray, vector, or side of a polygon).
Creating a perpendicular line
1.
Select Perpendicular Line from the Construct toolbox.
2.
Point to the line, segment, ray, vector, or side of a
polygon that will be perpendicular to the
constructed line, and click to select.
3.
Click to create or select the point through which
the perpendicular line will pass.
Note: The order of steps 2 and 3 may be reversed.
Modifying a perpendicular line
Move a perpendicular line by dragging the point through
which it passes.
The line cannot be altered directly because it is, by
definition, a dependent object.
Example
Select a linear object.
