3D Construction Line > Perpendicular to Edge (3D Menu)

This command can be used to create a 3D construction line perpendicular to a line through a point in 3D space. A construction line behaves like a construction aid line in 3D space.

Any component edge or construction line can be identified as the reference line for the perpendicular by clicking near to it.

Any component corner can be identified as a point on the line by clicking near to it.
