sub-assembly interference check

I have a question regarding one of the options for interference detection, specifically the option to Treat sub-assemblies as components.

I have an assembly which consists of several sub-assemblies and wish to check for interference between 2 of the sub-assemblies. These sub-assemblies consist of sheet metal parts w/ PEM hardware, so there is interference within each sub-assembly. I toggled on the Treat sub-assemblies as components option and performed my check. I was greeted with a whole pile of interferences which were the intentional interference between the PEM components and their respective mounting holes. The interferences reported are entirely within one of the two sub-assemblies I wanted
to check.

From the help:

Treat subassemblies as components.

When selected, sub-assemblies are treated as single components, so interferences between a sub-assembly's components are not reported.


Am I missing how this option works or is it not working? I thought this was fairly intuitive.....

Thanks,
Dave Gowans

I too run interference checks on assemblies containing sub-assemblies with PEM fasteners. I found that a good method to by-pass the PEM interferences is to run an interference check on the sub-assembly. When the intentional interferences from the PEM fasteners show up, select to ignore them. Then save the sub-assembly. Those interferences will then be ignored in upper level assemblies.
