how we are making flat pattern in ug nx 7.5 from solid model
I quickly did this in SolidWorks but NX should be similar. The problem with cad software’s figuring flat patterns is that they cannot calculate deep draw type forming, only linier bends (using k-factors). So remove the curves then fill them in after on the flat pattern. Really it an educated guess and you will have to adjust this flat pattern for your real world application.
