Hello. For context: I'm really a beginner on SW, and I'm boose under SW 2011. Do stamping parts have to be registered in SLDPRT or SLDFTP and required or not in the design library? On the one hand. And on the other hand, when I slide my stamping part onto my sheet metal, I get an error message, like: "This function will create disjoint bodies. Multiple sheet metal bodies are not supported." Do you have any advice to guide me.
