Backedges Style 2D Export

Napper

Hi everybody,

I got a bit too excited about Sketchup8 because I thought they had finally figured out that back-edges might be useful. Unfortunately, however they do not export to DXF/DWG. I was searching the forums for a while already - does anyone know of a plugin or workaround for this?

My workflow:

Model everything in Sketchup down to the last detail
Find the right views and section cuts using parallel projections
Export these to 2D DWG
Import into AutoCAD for making Construction-Drawings (which is essentially slapping on some measures, some comments, and putting everything in a nice frame.
Print.

So far this works great, except that "back in the days" I used to show back edges as dashed lines, which is pretty much impossible now because all lines that are exported have the same characterstics.

Tryed Layout - brilliant! BUT SO SLOW!!! It's hardly usable on my machine.

So - anyone know of a plugin for that?
