Folding with attached objects

[buganini]

Hi, I made some modifications to make bending KiCAD-exported STEP easier.

Ref: https://forum.kicad.info/t/flexboards-bending-and-step-export/26391/9

My fork:
https://github.com/buganini/FreeCAD_SheetMetal

So far it just applies the same transformation to clones of objects listed in attached objects and it is now usable for mechanical collision checks

I am looking for improvements for:

• Better cloned objects management
• Automatic enumeration for attached objects (overlapped on X-Y plane)
• Bending other layers like the copper layer in this image:

However, bending other objects isn't as simple as applying a transformation.

Any idea?
