You can use the Part Compare page to edit the settings which affect part compare.
RapidCut conversion tolerance — When mixing 3D solid and RapidCut simulations, the images must be converted from one type to the other by FeatureCAM. If you want to improve the quality of the part when it switches representations, decrease this tolerance.
Show rest material — Regions that have extra material greater than or equal to this value are shown in blue. The more rest material there is, the darker the shade of blue.
Show gouge — Regions with gouges greater than or equal to this value are shown in yellow. Larger gouges are shown in red.
Regions with rest material less than the Show rest material parameter or gouges less than the Show gouge number are shown in green. These areas are considered correctly cut.
