No geometery when I import cad into Sketch-up

[EhmannA]

I have been trying to import a cad file into sketch-up, but when it imports everything else that I have been working on it the file disappears and the cad file shows up as a line that runs along then blue axis. Anyone have an idea how to fix this?

Try saving your CAD file to an earlier version like 2007 and then import it OR save your CAD file (.dwg) as a .dxf (2007) and then importing it...

I have the same problem and ive been trying to save it into different options and i still get no result, i have 26 layers with different solids in each layer, and whenever i try to import it to sketchup it will only import some polylines, it imports all the layers but no geometry at all. I'm starting to think that it might have something to do with the fact that i'm using a macbook pro...
