Guidelines for Unbending a Part
Keep in mind the following points when unbending a sheet metal part:
• Best practice is to use a planar surface and not an edge as a fixed geometry reference.
• The part-level fixed geometry reference is used as the default feature reference.
• When you toggle from automatic to manual selection, all the available bent references are added to the Bent geometry collector.
• You can use the Flat Pattern Preview tool to open a window with a preview of the sheet metal model in an unbent state.
