I have a drawing with 12 assemblies and 12 parts attached/added to it. Must I activate each model separately and regenerate or is there a way to regenerate all associated models at once via the drawing? It seems the former approach would be very impractical. Thank you.
Anytime you are in a drawing, regenerate only works on the active model. If you have an assy active, it will regenerate the parts in that assembly. I don't know of a way to regenerate all assembly models added to a drawing without activating each one.
Here is another link about regenerating drawings and models:
