I use AutoCAD LT 2000, so hope some of this advice is useful...

I've found that something is broken in the dxf export - AutoCAD LT throws raspberries every time I try to import a dxf created from AC3D. Not been a problem so far, since I'm always going from AutoCAD into AC3D to build the 3D model.

For 2D work, I've found that Illustrator 10 is more forgiving, and will read the dxf data that AC3D exports. I then re-save as dxf or dwg in Illustrator and read that into AutoCAD. (NOTE: I have to rotate the plan (XZ) view into the Front (XY) window in AC3D before exporting in order to see the plan view in Illustrator.)

For 3D work, I just tried reading the dxf created by AC3D using 3D Studio VIZ and it does work properly. Re-saving the resulting file as dxf allows AutoCAD LT to read it properly and display in 3D (in AutoCAD LT use View -> 3D Views -> SW Isometric). But if you don't have access to VIZ or another 3D package that really isn't going to help matters. Using the Illustrator trick above is not an option, since Illustrator throws away all of the 3D data in the model.

I don't have access to a full version of AutoCAD, so I don't know if the import problems are specific to LT or not.

btw AutoCAD LT is capable of displaying 3D models in dxf or dwg format, but lacks the tools needed to edit 3D geometry.
