I have a weldment multibody part consisting of four parts, three parts are rolled plates, thickneses from 5/8", 1/2" & 1/8". Inside radius is 24" for the 5/8" plate & 25 3/8" for the 1/2" plate & 25 1/4" for the 1/8" plate. Unfortunately the tutorial provided does not help me understanding what I need to do to create a flat pattern.

Thanks in advance.

Regards

Serge JG
