I was hoping to get feedback on the attached model. It was created in Creo 3.0 M130 as a sheetmetal part. The feature I am seeking input on is the flat_pattern/bend_back. The relations measure the part, outputs measurements to parameter and the smt_thickness drives the material parameter. The family table instance for the flat pattern supresses/resumes only the bend_back for drawing/deliverables. Thru Pro Program, I manually moved the bend_back to the end of the model tree to keep the measurements in the flat_pattern feature "live" at all times. (Creo forces flat_pattern to bottom.).
