Thanks for moving Gaieus. I didn't mean to put in the wrong subforum.
I am going to try and chat with TIG in more detail and will post a solution when I have a solution.

Hi Hugh,
There is a plugin to import dxf text (I guess these are the things the native SU importer will not import for you).
But why are you posting this in the Google Earth subforum? If there is no special reason, I am moving your topic under the main SU forum if you don't mind.
