Transcription: The designers of Donner and the X-Trafting include B-Directional interfaces, such as DXF, double-G and GOS. The model complements exist to communicate with Katia, KADAM. They also use the utility of Donner's GXF to create a list, research, deploy, copy, rename or create a plan. Plus, they use a comparison of the three tools to make the difference between the most recent versions of design.
