I have an IGES file and I am using NX8 to open it and I need to unbend/unfold the part and I tried to use the unfold command but it didn't work any suggestion?
Is it a sheet metal type of design?
As it is imported, you'd likely first need to convert it into a recognized sheet metal design, then the unbend/unfold command may recognize it.
Sara, If it is not top secret, you might post it here, or send it direct to another user. The part would need to have uniform wall thickness, and not contain any compound (two directional) bends in order for it to convert to a sheet metal part.
Even a picture might help to diagnose a problem.
I tried to use the command convert to sheetmetal but was not successful , it refused to choose any surface of the model .
