About Unbending and Bending Back Board Segments
Use the Unbend tool to unbend one or more curved surfaces such as bends or curved segments. Use the Bend Back tool to return unbent segments to their formed positions. You can manually select individual geometry, or you can automatically select all geometry to unbend or to bend back. When you create an Unbend or Bend Back feature, you must define a fixed planar surface or edge. Best practice is to select the same surface for all Unbend and Bend Back features. You can save time and maintain consistency by setting at part-level a fixed geometry reference for all Unbend and Bend Back operations.
Keep in mind the following points when creating a Bend Back feature:
You can perform a bend back operation on a part with more than one piece of unattached geometry. However, each piece must be bent back using a separate operation. Only manual selection of unbent geometry is available.
Best practice is to use a planar surface and not an edge as a fixed reference.
You can set which contours that partially intersect a bend line to remain flat during a bend back operation.
When you toggle from automatic to manual selection, all the available unbent references are added to the Unbent Geometry collector.
The part-level fixed geometry reference is used as the default feature reference.
You may not be able to return an unbend feature that contains a deformation area to its original position.
You cannot bend back a Cross-section-driven Unbend feature.
