Import contours DGN and export as SHP
I'm looking to import contours that were created in MicroStation and export them as a Shapefile. When I import the DGN's the contours all come in at the same elevation, I lose the Z value (elevation) of the contour line when I import them into Global Mapper. When I view the DGN's in AutoCAD or MicroStation they are in 3D and displayed correctly.
How do I import the 3D DGN files so they are in 3D in Global Mapper?
