Constrain linear objects or line segments to be perpendicular to one another. If one line is rotated, the line it is constrained to adjusts to remain perpendicular to the first line. Lines do not need to be perpendicular when placing the constraints; the first line rotates to become perpendicular to the second line.
To constrain lines to be perpendicular:
1. Click the Constrain Perpendicular tool from the Dims/Notes tool set.
2. Click on the line to constrain.
The cursor switches to the bull’s-eye cursor.
3. Click on the line to be constrained.
A green perpendicular constraint is drawn, connecting the two lines.
