No problem esc, just throwing things out there, I'll try not to beat that dead horse anymore.

Anyway, I'm not a guru of CAD myself, heck, I don't even have a degree, and am pretty much self taught when it comes to CAD and engineering, with the exception of some CAD training courses and too many years in a machine shop. That 2% +/- loss was taught in every training course and from every instructor and engineer I've talked too and worked with, but since the DXF format was made by Autodesk, I'm sure their translator is geared towards it, which gives you a cleaner conversion. But, if you were to take the same DXF file and import it into either Pro-E or SolidWorks, the results would be different, it all depends on the translator. I used to use SurfCam's translator to convert files to input them into Unigraphics, a double convert, but it still came out better than what the UG translator would give you. I agree if the initial file is made correctly there's less loss of data when converted.

Here's an easy test to try, take a DXF and IGES file of the same part and convert it in Inventor (or any CAD program), then save it in it's native format (DWG or whichever it is), then compare their file size between the DXF/IGES and the native file and let me know what you get.

Just having some fun, don't take me too seriously, I get caught up in the details sometimes and rant on.

Look forward to your build thread,
Dean
