Autodesk actively encourages the development of third party software which works with AutoCAD and aids its use in vertical markets. Autodesk has established the AutoCAD Applications Program as a channel by which developers of such programs may communicate with AutoCAD vendors and users. The first AutoCAD Applications Catalogue contains more than 100 such programs. Autodesk derives no revenue from these third-party programs except that generated by additional sales of AutoCAD they engender. However, the Company believes that this Program is an excellent way to identify and qualify programs for possible acquisition, joint marketing, distribution, or licensing by the Company.
