      *As with all performance tests, results may vary based on machine, operating system, filters and even source material.

      * Productivity data based on a series of studies commissioned by Autodesk to an outside consultant. The seven toolset studies compared basic AutoCAD to the specialised toolsets within AutoCAD when performing tasks commonly done by experienced AutoCAD users. As with all performance tests, results may vary based on the machine, operating system, filters and even source material. While every effort has been made to make the tests as fair and objective as possible, your results may differ. Product information and specifications are subject to change without notice.
