I'm working in an assembly with a couple of subassemblies and I'm trying to mate an assembly that has mates in another configuration, but they are all suppressed in the one I'm working with. When I try to add a new mate, it tells me that adding this mate will over define the assembly even though all the current mates are suppressed. Is there a way to fix this without deleting all the suppressed mates?
it sounds like all of the components are "fixed" in that configuration. right click on them and choose "float". this will probably unsuppress the mates, but you can suppress them.
