I'm building waggons for a model railroad. I etches a sheet of brass so I get partial cuts in the sheet and I then bend the sheet at these cuts. The depth and width of the cut is half the thickness of the sheet and the bend is 90 degrees.

I need to be able to unfold the sheet to get the drawing for etching. But I cannot figure out how to solve this in SolidWorks.

I can either do a bend but no unfold, or I can do an unfold but not a correct bend. I think the problem is that my sheet of brass has different thicknesses and I don't know how to get SolidWorks to accept that.

Regards,
Daniel
