In Pro/E you can open a model, do a "save as" under a new name, and a new model is created along with a new drawing of the same name (with a .drw extension). The new drawing references the new model. The names of the original model and original drawing have to be the same for this to work.

Is there anyway to do this in SolidWorks? It appears to me that you have to make copies of both the model and drawing seperately then link the new drawing to the new part.
