Ok it is not my post but let me give you a scenario where we use File -> Export -> Part to achieve what is being asked here. We download or are delivered a solid model of a part from a supplier. We have an internal part number established for this suppliers "Assembly". Our part number/documentation defines the entire assembly, we don't care about the subcomponents in the assembly. So in our soon to be PLM integration we will want this part to exist as a single part file which will be a document tied to the material in PLM. We don't want to have a bunch of extra documents to create and manage in PLM to represent the subcomponents in the assembly as those are non value added items to us. Make sense? Is there some better method or practice we should be following in this case? A recent example is for an Ethernet connector that we purchase that goes on a PCB. Suppliers model is an assembly. Had like 4 components. I just want a single piece part for the whole connector.
