When importing geometry in STEP,Iges, Parasolid etc we get no mates.

It would be good if SolidWorks could add simple mates like concentric and coincident.

We have the api to do it.

That would be an advantage when needed to migrate data from other systems.

SolidEdge seems to have this capability and some request of similar (and better) functionality is wanted.
