(DXF) computers 1. the ASCII text files defined by Autodesk, Inc., at first for CAD, now appearing in third-party GIS software 2. an intermediate file format for exchanging data from one software package to another, neither of which has a direct translation for the other but where both can read and convert DXF data files into their format —note this often saves time and preserves accuracy of the data because the original is not reautomated This definition last updated 10/25/2008
