I have an issue when inserting multiple new parts into an assembly when the new parts don't share the original assembly's coordinate system.
I insert parts, transform them with the available tools to desired locations, save snapshots, and save the session file as needed. Next, I insert more parts, save more snapshots, and resave the session file. Lastly, I want to see the earlier snapshots with later inserted parts in their intended positions also, but I have not found a way to do this (because once I apply a snapshot any part that was added after that snapshot was saved will apply the transforms for that snapshot and since there are none for the later added part, the later added part will reside at the default CSYS).
Any tips or tricks on how to have more control over transforms?
