You're more than welcome. Be aware, though, that the DXF file size can get VERY large compared to a .dwg file. It appears to be mostly to do with the number of objects in the drawing. Avoid using hatches / fills in any drawing being saved as a dxf, as an area of hatch will count for many thousands of objects. Even if gINT can import the file, it will be virtually un-navigable as the redraw times will be very high (many minutes, each time you do anything) Also be aware that if you are modifying drawings with title blocks etc in Drawing Space and exporting them to dxf, remove anything on the drawing space tabs before you export, as they often import at 0,0 coordinate (or less) which means if you click on the zoom to fit button in gINT, you will end up with a tiny dot bottom left (the title block) and a tiny dot top right (the main drawing) Hope some of that helps :-)
