Is DXF only for 2D drawings? What we ideally need to be able to do is generate sections, which I understood required 3D models (but I have virtually no knowledge on this).
I've only used DXF for 2D and only then for transferring files, I think it probably does 3D data and DWG definitely does. If you are "generating" sections from a 3D model it would have another format. But you can (people still do) draw plans and sections as 2D CAD drawings (3D model not required).
