Just been futzing around with this some more to see if it’s good enough to make a first go at doing my wiring diagram.
I tried using the layer order to determine the draw order and that works fairly well.
First I set up 3 linetypes (could do many more), all by mm (not pixels):
1 dashed at 1.5mm
1 solid at 1.5mm
1 solid at 1.8mm (outline)
Then for each wire color there will be a master layer and three sublayers in order
Dashed, Solid, Outline - with the layer colors representing the wire colors. The outline is black to separate from the paper.
It’s still pretty kludgy to do…
First draw everything in simple line form
Then for each wire color, select all the lines and change to the first sublayer, then copy to the second and third sublayers. Group the 3 polylines for each wire together.
Still a lot of work unfortunately, but that’s all I can think of.
