Combining the Different Sheet Metal Design Methods Parts that are originally created as sheet metal have different features than parts that are created, and then converted to sheet metal. However, you can add sheet metal-specific features to parts converted to sheet metal. As soon as you add a sheet metal-specific feature, (a Miter Flange , an Edge Flange , and so on), bends for new sheet metal features are stored under each individual feature instead of under Flatten-Bends1 or Process-Bends1 . Additionally, all new bends are listed under the Flat-Pattern1 feature. To flatten the part, unsuppress Flat-Pattern1 rather than suppressing Process-Bends1 .
