DXF Formatting Question

post #1 of 2
Thread Starter 
As some of you already know, I am a graduate student at the University of Iowa, and as part of my Master's thesis, I am modeling clothing resistance force to movement using finite element analysis and motion capture data to drive the 3D clothing mesh. AutoCAD is the easiest way for me to edit the 3D meshes to our needs, but in doing so I have encountered a problem...

I have written a program to convert a DXF file of a 3D mesh into a usable format that does not have all the extra junk, for use with another program (Tecplot to be specific, which will be used to create animation videos). My conversion program reads the coordinates just fine, but for some reason the coordinates are not the same as what is displayed in the AutoCAD GUI. That is, the coordinates in the reoriented DXF file are the same as they were before reorientation, so running my program leaves me with the initial coordinates of the 3D mesh (before reorienting the 3D mesh).

My question is then do DXF files have axes transformation information listed somewhere in the file? If so, where? I have tried saving the DXF file as a whole, and just saving specific objects to DXF files but the result is the same. Also, if you think something completely different is causing this discrepancy, please let me know!

Thank you very much!

I would like to point out the importance of this issue. The longer it takes me to solve this, the longer I have to wait to finish my thesis and thus graduation is delayed...
