About Transitional Unbends
Use the Transitional Unbend tool to unbend a sheet metal part with undevelopable geometry such as a blended wall, which has bending in more than one direction. You select stationary surfaces and transitional surfaces to determine the shape of the unbend feature. After you unbend an area you can continue to add features, like cuts and rips.
