Hello,
When I export a MX model to DWG, I get 2 files. One is the 3D model. The other is a 2D model. The problem is that the 2D model contains 3D polylines with no elevation. A 3d polyline cannot contain a width. Therefore it should be converted to 2D polylines.
It is possible to set the planar line strings to polylines instead of 3D polylines in the options dialogbox. No matter wat setting it is, the export keeps containing 3D polylines. It can be solved in AutoCAD by using a lisproutine, but it is a setting in MX/MS that should be working. (in SS3 it worked...)
With regards

Hi Gunther,
Make sure you export to Native DGN first and export the Native DGN to DWG. This should definitely fix the 3d polyline issue. There seems to be an issue when directly exporting MX strings to dwg for the later ss3 builds (still happens in ss4).

True, I think it's a result of Bentley trying to maintain compatibility with new AutoCAD versions and it looks like it may have issues for the later versions of MX. Everything else is okay though and the Openroads advancements are pretty impressive with each new version.
We have put together a Macro that exports the current mx drawing to Native, opens it and exports to dwg with a single function key. Unfortunately this is the only way we could find to get our exports looking the way they previously did. It does work quite well though.
