As a very active user of FreeCAD (Many thanks to all of the developpers) I often use it to design small sheet metal parts. As it is now quite cumbersome to make such parts I decided to add a simple Shet Metal workbench. It is not such a big deal but it make my sheet metal design go much much faster. I have posted the Module and some help how to use it in my projects website: http://theseger.com/projects/2015/06/sh ... r-freecad/
Hope this helps others!
