     The DXF format is AutoCAD's external format for drawing interchange.
Look in any AutoCAD manual.  It's an ASCII text file, rather bulky but
not too difficult to process.   Autodesk, Inc., (Sausalito CA) defines
DXF format.  

     IGES, the Interim Graphics Exchange Standard, is an industry draft
standard for drawing exchange.  I don't know the controlling organization
offhand, but it's not ANSI; the standard isn't that well developed yet.
IGES files are organized as 80-character fixed format ASCII text records,
and are somewhat FORTRAN-oriented.
