In Mastercam 2024, the traditional on-screen gnomon has been augmented with the Gview cube, a more graphical way to show plane orientation. The Gview cube, which is relative to the WCS by default, also features many options that let you control the cube, thus the on-screen representation of your part.
The cube itself has many interactive features. For example, double-clicking the cube fits the part to the screen (same as the Fit command). You can click a side, corner, or edge of the cube to switch to that view. Drag any part of the cube to change to a view, unconstrained by the preset views represented by the sides and edges.
