Unfold/Fold

With the Unfold and Fold tools, you can flatten and bend one, more than one, or all of the bends in a sheet metal part.

For faster system performance, unfold and fold only the bends that you need for the task that you are performing.
This combination is useful when adding a cut across a bend. First, add an Unfold feature to flatten the bend. Next, add your cut. Lastly, add a Fold feature to return the bend to its folded state.
