Hi TIG
Thanks for your input.
As i wrote, I was looking for a script that could split a face so it became a part of the model as lines, so they could have the same style as other lines in the drawing. I hoped that protrude would help me - but I can't get it to work π
I have added an image that shows the result - I have to add the lines manuel.
