The macro can unfold simple sheet-metal-parts. The parts must have everywhere the same material thickness as typical for sheet-metal-parts. See example:

Usage

Select a flat face from your part in the 3D-view. Start the macro.

Remarks

The macro creates a lot of text in the report-view. This is still a remains of the debugging process of this macro. The edges of the sheet-metal-part may be round or slanting. But if you "walk" from the upper side to the lower side of the sheet-metal-part you should not cross more than one face. In best case the macro generates a new flat solid from your part. If the macro has problems, you may get only a flat shell or a bunch of flattened faces or only an error message.

The macro can be thought of as a companion to the AddWall tool from JMG published here: FreeCAD: Sheet metal tool "Add Wall"
