I have two sub assembly. In both of them, I have a part of sheet metal which is bend and welded with other parts. Now I want to show before and after bend in drawing, how can I do that? I have tried saving two separate drawings, but it find references automatically and links to original bend parts. The bend part is build with Flange and Edge bend. Here is the example which I did, but both are separate. Is there anything where I can do with a single file?
