Draft Snap Perpendicular

Description
The Draft Snap Perpendicular option snaps to the perpendicular point on edges. The edges can belong to Draft or Arch objects but also to objects created with other workbenches.

This snap option will also find points on the extension of straight edges. Circular edges are always treated as full circles, if a circular edge is an arc the point that is found may not lie on the actual edge.
