The Draft Snap Perpendicular option snaps to the perpendicular projections of a previous point on faces (introduced in version 0.21) and edges. The faces and edges can belong to Draft or Arch objects but also to objects created with other workbenches.

This snap option will also find points on extended faces and edges.
