Now that Autodesk is recommending View Reps more than LODs and enhancing their performance in such areas as Express Mode, this idea will help us break from using LOD reps a little more:
Allow view reps to help us calculate mass of assemblies when some of the parts are turned off like LOD reps do now. This would allow us to have various weights associated with various reps for use on our drawings and etc without having to suppress the parts in an LOD rep.
When calculating mass we often have to turn off parts to get the mass of some sub assemblies. LOD reps allow us to choose between calculating mass of the LOD rep or of the Master Rep. We need to do the same thing in View Reps.
