Mate References With and Without Names - Computer Aided Technology
Summary
Then it’s just a matter of dragging and dropping the part (from the Design Library for example) into your assembly and having it snap in place when you get close to where you want it. This is the “best case scenario” that would give us 2 mates (Coincident and Concentric) if the user dropped it onto another circular edge. The order that you select the faces for Primary, Secondary, Tertiary isn’t for priority anymore. We also have another part with a Mate Reference with a name, AND more importantly has corresponding faces that “match” and they were selected in the same order for the Primary, Secondary, and Tertiary… When you get these two parts into an assembly and you get them close to each other they will snap together and use ALL 3 references to fully define the position of the component! NOTE: It is widely misreported in many places that the names of the Mate References have to MATCH for this second way to work.
