New in SolidWorks. Building family table of SHCS and I want to add mate references for easier assembly of bolts. No matter what I do, when SHCS is inserted into assembly, only concentric mate (1st mate) works, second mate (coincident) does not work. If I place coincident as first mate and concentric as a second one, then coincident mate works but concentric mate (as second one) does not work. Am I missing something?
