I'm trying to follow this page of the tutorial. The distance mate is grayed out when I try to make one. How do I make it work?
The only thing that I can think of is that you may have selected 2 different entities from the ones that it suggested that you use when you originally created the coincident mate.
A coincident mate between two planes or planar surfaces, can be changed to a distance mate.
But a coincident mate between 2 edges cannot be changed to a distance mate.
Neither can a coincident mate between a circular edge and a plane or planar surface.
See attached video.
