Discovered an issue, when I open an NX9 part that contains a flat pattern, and then I go into drafting (same part file) and try to add the flat pattern view, it fails.
If I create a sheetmetal part from scratch in NX11, I can add the flat pattern view. I have also tried deleting the flat pattern, and recreating it in NX11, but it agian fails.
I did submit an IR, but curious if anyone else has run into this, or has thoughts on it.
