I didn't into detail, I simply changed the license, you recommendation. I also added "cross reference". If the same conductor has "Going arrow" or "Coming arrow" attributes, then take the opposite ends and connects them. Need more test.

Hello Baruse!

Very impressing! 
Even as an excited FreeCAD user... nomicons/smile

As I am still planning and writing a code to create wiring-plans from QET-Drawings, I struggle with coming-/ going-references and elements that aren't real parts like jumps and splices:
Does your script handle some of those?
Does your script handle diagrams that have more than one folio and use references?

Please don't feel offended: Just simple questions!

cross reference and cable still in my mind, but now it doesn't work

I chose this license because it appear to me that it give of freedom, but maybe I'm wrong (I'm not skilled about legal matters). I think we can change it, if it not correct.
I think it should be as free as possible with Freecad compatibility. Need help with this

QetWireManager
I created a script in collaboration with AI nomicons/wink
Freecad script will allow you to import wires(conductors) from Qelectrotech and manage it in 3d space and get wires length

I created the script for my own needs, it satisfies me so far, but comments and requests are welcome. Video with instructions is on github
P.S.
