The "customer involvement program" (CIP) is a tool for online reporting of software bugs and of the ways how customers use AutoCAD, Inventor and other Autodesk products. The offer to take part in this program is displayed when you launch AutoCAD - you may remember this picture:
This tool can help you to get help or a fix if your application happen to crash. Autodesk is also using the anonymous data collected through this tool to optimize the user interface and the most used commands.
