We usally have a fair amount of cylindrical parts in our assemblies. We usually dont fully constrain cylindrical parts, and let them "spin". Our VAR said this will speed up rebuild times, as well as design time since you dont have to do an extra mate. My problem with this is, I look at my design tree at the end of a design to see if everything is fully constrained. All cylindrical parts still have a - sign next to it, so I have to check them to make sure they are defined except for spining.
Is there a better way to do this? It can be rather time consuming checking all cylindrical parts to make sure they are indeed only spining about the axis.
Suggestions/comments welcome. Thanks.
