Here's what to do when you're stuck in Mastercam.

<iframe src="https://www.youtube.com/embed/mPq47Zw7jto" title="YouTube video player" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen style="position: absolute; top: 0px; left: 0px; width: 100%; height: 100%; border: medium none;" width="560" height="315" frameborder="0"></iframe>

Often times you will find yourself in a Mastercam Function or Toolpath and you may be unsure of what a setting does or what changes may result from its use. A good first step is to see if you can help yourself!

Mastercams Help files should be your first stop whenever you encounter an issue. The help file can be accessed from many different locations. Typically, it is best to access Help while you are in the function you are having trouble with. This will launch the Help document directly into the section related to where you were when you clicked the question mark.

Speaking of the question mark, look for this symbol through out Mastercam. This is the easiest way to launch the Help document. When you are not in a Toolpath or Function, you can find a Question Mark icon in the top right corner of the graphics interface. Alternatively, you can find access to the Help document through the File Menu. Click on File, and then near the bottom is Help, from there you would select Contents to open the Help Document. Launching from these two methods will open the document on the Main page.

The Help document is now an HTM file instead of a CHM which it has been in the past. Now, the Help file will open in your web browser.

There are some other documents which may be of interest to some. These can be found in the following location (if the default install locations were used)

C:\\Program Files\\Mastercam 2021\\Mastercam\\documentation\\en-US

Here, you'll find additional documents such as Transition Guides, Whats New, Quick Reference Cards, Administrator Guides, and others.
