Mastercam Selection Tech Tip
A: You can use Mastercam’s “Quick Mask” tools to de-select as well as select items. A handy tip for the situation you describe is to select all items on your screen, then click the “surface” Quick Mask button. Since all items on screen are already selected, clicking that button will de-select just the surfaces. You can add the Quick Mask icons to your toolbar by dragging them from the “General Selection” group under Settings / Customize.
