it is nearly impossible to select multiple sub-assemblies with the new geometry based filter. I have spoke with PTC and with a very convoluted non-intuitive method finally was able to perform this task. To prevent me from jumping off my desk, I created a couple of mapkeys to add parts and components to "my filter" and another to reset it back to geometry once my selection was complete. Has anyone else encountered this and what did you do to resolve this?
