Perpendicular Line Tool

Activate the tool, then select a line (or a segment) and a point to create the straight line through the point and perpendicular to the selected line (or segment).

  • The line (or segment) must be already existing in the construction. The point can also be created on the fly with a click (or a tap) in the Graphics View.

  • The created perpendicular line has the same direction as the perpendicular vector to the selected line or segment. (See also the PerpendicularVector command).

  • This tool has also a 3D version: Mode orthogonalthreed.svg select a point and a perpendicular line or plane.
