As a result of user feedback, we update the SolidWorks Help on a regular basis. We primarily receive feedback through the Feedback on this topic link that you can find at the top of each help topic of the Web Help. Your feedback helps us provide the documentation that you need. We very much appreciate this feedback, and encourage all of you to continue to provide it.
