A rule of thumb for export:
2D views are exported from the plan or section windows.
3D views are exported from the 3D window. Experiment with file formats for the best mode of interchange. DXF will be the lowest common denominator approach and therefore probably wretched in terms of what you can do with the information exported.
If all you want are lines that's ok.
