The 'contextual help' just throws you to the beginning of a big HTML document. There's no reference manual that I can find that lists all the things it can do and what all the menu options do.

The documentation (at Documentation - InventorCAM CAM software) consists of endless tutorials and fuzzy videos of screenshots. Switching back and forth from the Inventor model to the CAM environment (Crashes sometimes, and sometimes just loses the CAM environment.).(Crashes every time, by bringing up a dialog box with one greyed out 'Resume' button from which there is no escape.)

When it crashes, it takes Autodesk Inventor down with it. I'm a programmer who does some machining.) I've used Inventor extensively, and SolidWorks a little. I've used Aspire's Cut2D and VCarve, and Sprutcam in the past. (Background: I'm using InventorCam 2012 with Autodesk Inventor 2013, at TechShop.
