Mastercam Bounding Box Options

Let’s take a look at new options added to Bounding Box in Mastercam 2021. Bounding Box now allows you to create stock limits using an auto option. This will allow you to take parts that have odd shapes and quickly create rectangular or circular stock that will fit the selected parts as tightly as possible. In practice, you can use this Rectangular or Circular boundary to quickly align the part for milling or lathe operations.

To use these new features, you need to launch Bounding Box from the Wireframe tab.
