As an architect, often in need of exporting logos to dwg/dxf, I also support the request for dwg and/or dxf export*.
Specific use cases include, for example:
- Drawings' title blocks (one logo for each member/practice of the design team)
- 3D models (customer's logo on the façade of a building)
Being able to select dxf version would also be useful (Blender can currently only read DXF Release 12, to my knowledge).
*Edit: Apologies, only later realized this is off-topic, asking for exporting while OP asks for importing.
