Generic CADD (ver 6.0) Abandonware Generic CADD was a popular, and much easier to use, 2D CADD competitor to AutoCAD. In the late 90's, AutoDesk acquired Generic CADD, then discontinued it. CADD.exe is the executable. CONFIG.exe will change the video, pointers, printers, and drawing defaults. ACON.exe will both change the default paths (currently configured as "\APPS\CADD6") and convert Generic CADD drawings to and from AutoCad *.DXF files.
