About Bending Back Walls
Use the Bend Back tool to return unbent walls to their formed positions. You can manually select individual unbent geometry, or automatically select all unbent geometry to bend back. When you create an Bend Back feature, you must define a fixed planar surface or edge. Best practice is to select a the same surface for all Bend Back features. You can save time and maintain consistency by setting at part-level a fixed geometry reference for all Unbend, Bend Back, and Flat Pattern operations in the Fixed Geometry dialog box.
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 shall 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.
