Hi Glyn - that will convert any curves you have over into curve objects in the DXF file, but it won't handle transferring surfaces or solids.

To transfer surfaces or solids, you will have to export to some other polygon file format such as .3ds or .obj and then use a format conversion program to create a polygon mesh .dxf file from that. Let me know if you need to do this, I think there are some free converters out there that can handle this part - they don't do wireframe curves though which is why I made that other utility.

For version 2.0 I want to work on adding DWG/DXF support integrated directly into MoI.
