And if that didn't work maybe we tried exporting to SAT and import it in Revit. Pretty decent, but sometimes the geometry went curly when the coordinates were to high numbered.
As stated, there are many ways to import 3D-DWGs into Revit, but I have yet to find one that really suit my needs.
Then I got inspired when I saw the new features in Dynamo 0.9.1 here. a little down on the page you can read about dwg import possibilities in 0.9.1. Alas, it is only available in Dynamo studio, which I find a little worrisome. Hopefully it will be integrated in Dynamo for Revit sooner, rather than later because this is miiiiles ahead of native Revit import of DWGs. Read all about the new functionality here.
Soooo, a test was required.
The original DWG:
Just a test file, but it is a bridge model consisting of surfaces made by software called Novapoint Bridge.
In Dynamo Studio:
If the DWG nodes were available in Dynamo for Revit you could skip the SAT part all together and cope with one script.
The result in Revit:
You be the judge, but I for one thinks this method gives me a far more usable link between a 3D-DWG and Revit environment.
