I am working on electrical ladder and one-line drawings. On the drawings, where two wires cross but don't connect, the standard is to have a semicircle jump over on of the lines. Years ago I had a lisp routine that worked great. You would select the vertical line, then select all of the horizontal lines that jump over it. I would place all of the semicircles and appropriately trim the lines.
Does anyone have anything like that or something close that I could modify?
