I have an assembly with sub-assemblies and some sub-sub-assemblies. In the main assembly I have seven different configs, one showing each sub-assembly so that I can use it in a multiple sheet drawing and get the BOM and balloons to work correctly. I'm trying to use the "Reuse Sub-assembly Explode", and it works as expected on most of the sub-assemblies, but not on two of them. I can't figure a rhyme or reason for this. Has anyone ever experienced this, and can tell me what to check for?
