Thanks for your quick answer.
In my house, I have around 50 walls which need to electricity. The guys who do the electricity should get a plan exactly like this:

This is quite common, at least in Germany.
Of course I am able to export in *.svg, but only the 2D birds eye plan, but I would like to have every wall in a frontal view to draw the lines. This of course can be done with every Bitmap or vector illustrator.
Normally, you can do such slices e.g. with sketchup. But I dont like to switch to sketchup, because *.obj export did not work for me.
