Find the midpoint of walls on a 2D DWG

[rossthompson]

Hi All,

I use SketchUp for creating simplified models for analysis software.

These models need zones creating that pick up the midpoints of internal walls and the inside face of external walls. A screen shot is attached.

Typically this is done from an imported 2D DWG floor plan. The layers etc. will vary.

Can anyone think of a way to create these zones via ruby?
It seems like something that is easy to explain to a human but not so easy to code.

Thanks.
Ross
