* Productivity data based on a series of studies commissioned by Autodesk to an outside consultant. The seven toolset studies compared basic AutoCAD to the specialized toolsets within AutoCAD when performing tasks commonly done by experienced AutoCAD users. Overall productivity gain calculation based on adding the completion times of specific tasks in the toolset and also in basic AutoCAD and then calculating the percent difference between the two totals across seven studies. As with all performance tests, results may vary based on 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.
