I have designed something in solid works where, I have sheetmetal and regular extrusions, and then I split the part so that I can unfold parts and put them in aspire for CNC milling, but when I split them they seperate, but I can not unfold the sheetmetal parts, and in the part file there is extrusions, sheetmetal, screws, etc. My point is that there is not only sheet metal in the part, and I need to be able to unbend this metal, so i would absolutly love any help I could possible get.

Thanks, Daniel
