I have two sheet metal parts in solidworks. They both have a rubber capping around the edges. As i drew the rubber capping and the metal all as one part the material was the same for both. using the cut list items i was able to change the material to rubber on one of my parts. this picture attached shows that on my second part it wasn't coming up with any material option at all. I cant figure out how to change the material of the sweep without creating a new part.
