When I save a 3D DGN as a DWG,
it seems to get flattened down to 2D when I reopen it in MicroStation.
The following tip came from EatYourCAD.com: MicroStation
has an option that automatically forces 3D DWG files to be opened
in 2D. If you don't know this option is turned on, you may be
very surprised to find all your 3D DWG files including
ones you just saved from a 3D DGN file flattened down to
Here is how to turn this option off:
1. From MicroStation Manager or the Open dialogbox, select a DWG
2. Click on <DWG Options>.
3. Uncheck the box for Create 2D models for Model Space.
Untick the box to open your DWGs in 3D.
Thats all there is to it.
