BIM Translation to DWG issue.. (painful)


I am translating a set of drawings into the dwg format for a structural engineer. I've created sheet layers that contain plans, sections, and elevations. The plans and sections seem to be usable as far as clarity when I re-import them back into VW 12.5 after exporting each sheet individually. However, the elevations are of concern because the walls rendered in the viewport as "hidden line" become trianglated in the dwg. The elevations are a mess, see attached images. For simplicity and time constraints I would like to find a method of exporting the sheet in dwg for AutoCAD users so that they can be opened and viewed as they appear on the VW Sheet layer.

Is this something that I have to figure out a workaround for, as part of "dumbing down" a BIM project?

Make a copy of your model.

Set up the required hidden line view.

Modify--->convert--->convert to lines

This will give you a clean 2d representation.

I'm not sure this is what you are looking for however.

[edit] if you try to round trip the drawing, it looks like you will always get multiple 3d polys for your walls.
