Unfold / Flat Pattern
Unfold / Flat Pattern
(OP)
Dear All,
I could use your help to create a flat pattern feature of sheet metal body. I can't figure out how to make it flat, hence it is a surface with thickness of 1mm.
I have tried "global shaping" and "flat pattern" without any success. I don't have a advanced sheet metal licence.
Best regards,
spada

It strikes me however that this is probably not a 'sheet metal' part. It looks more like a 'pressing'.
If you try and flatten it you would effectively buckle somewhere in the middle or tear the corners.

Jon, yes it would probably buckle somewhere in the middle, that it is why I couldn't unwrap it. It was telling me that the shape was not developable.
Petulf, I am currently using NX10. Hope we can upgrade in the near future.
I haven't been able to unwrap it until now. From what I understand there is no way (or there is a difficult one) to unfold/unwrap a non developable face without an advanced module.

Unfortunately I'm not able to open your model since I'm using NX 9, but is there a chance that this short tutorial would be helpful?

Lockdain, this tutorial is very handy, but unfortunately it works only for "developable" surfaces.

This was a very nice approach. I will follow your steps. Thank you very much for the model.
