This functionality would make our lives much more easier and would enhance Creo Parametric performance and flexibility. For example:
It would reduce the number of files to be managed by Windchild (PDM), using only one single file (with several simpl. reps.) instead of managing one file per instance if the suggested workaround (family table) of the article were followed.
It would be very useful to deal with assembly cuts (i.e: machinning operations at assembly level) that modify the geometry of the components adding them to simplif. reps. and checking the influence in the total weight of the assy.
It would be very useful to add welding features to simplif. reps. and check the influence in the total weight of the assy.
When you are working with solid weldings, there is a problem because when you create a simplified representation excluding all, you still have solid geometry (created by the assembly features of the solid welding seams).
In general would be very useful to work with assemblies that include features that affects the mass properties of the assembly.
It would be very useful to help populating the assembly for MBD. Combined states could be created easily based in different simplified representations where you include/exclude the features that modify the geometry of the components with the advantage that the mass properties of the assembly in each representation could be evaluated independently.
