The computer-based training tutorials are helpful. You can start training in a game that is similar to a gentler version of DOOM or go straight to the lessons. Lessons cover creating a drawing, creating a family of parts, and assembling a part and a subasssembly. The on-line Help is very good. A left window pane shows the content tree, and you can clearly see where in the Help system you happen to be as you view the information in the larger right window pane.
Help provides numerous color screen shots with hyperlinks to related videos.
If you find a software bug, the built-in bug reporting system is clever. The Send a Note command brings up a request form that you can automatically transmit to think3 over the Internet. You can attach zipped copies of the file, screen shots, local computer information, and other file types with the form. For the ones that affect the most users, it offers workarounds and fix notifications in the Critical Issues section of the thinkcare Knowledgebase on its Web site. It presents less-universal problems and solutions when you click the Solutions and Search the Web buttons.
