Lisp that draws 3 lines similar to the Multi line command

I wanted to reach out to the community to see if anyone has a LISP routine similar to the AutoCAD multiline command, but with the ability to draw three lines instead of two. Ideally, the center line would be placed on a separate layer from the outer two lines.

 

At my company, we frequently trace building layouts to create floor plans in AutoCAD that include wall thickness. We also need to trace the same file in Illustrator to generate a single-line wall view. It would be incredibly helpful if we could trace the building once and then separate the centerline from the outer lines, allowing us to use the same traced geometry for both the AutoCAD plan and the Illustrator single-line export.

I've done something similar using Lee Mac's Double Offset, but it's heavily modified for drawing cables. Thats a good place to start though.
