IntelliCAD is a CAD editor and development platform with an API published by the IntelliCAD Technology Consortium (ITC) through shared development. IntelliCAD emulates the basic interface and functions of AutoCAD, however, it is particularly able to incorporate and interchange freely between a wide variety of file types (i.e., .dwg, BIM, TIFF, etc.).
ITC IntelliCAD is not sold directly to end users but is licensed to consortium members, who support the shared development by paying annual fees, similar to a co-op arrangement, in exchange for permission to distribute IntelliCAD-based solutions worldwide with their own end-user license agreements.
