(Update: I no longer work at the school referenced below, but will continue to keep this article up as long as it seems helpful to somebody.)
MasterCAM is an excellent CAD/CAM package that my school uses in a variety of classes including
Drafting, Precision Machining, and Wood Products Manufacturing. Unfortunately, graphics problems have plagued MasterCAM for as long as I can remember. We’re currently using Mastercam X4 and these problems present themselves in a variety of ways. One example is the absence of visual cues when a tool snaps to a particular point. Another is the missing “selection box” when you try to click and drag on your drawing to select a particular set of points.
This problem can usually be solved by disabling Hardware Acceleration (Windows XP). If you’re using Windows Vista or Windows 7, you’ll have a hard time finding the Hardware Acceleration window because, as far as I can tell, it no longer exists. Luckily newer versions of MasterCAM allow you disable hardware acceleration for MasterCAM only. To disable MasterCAM hardware acceleration, follow the following steps.
- Within MasterCAM, select Settings, Configuration.
- Click Screen on the left-hand side of the window to display the screen and video settings.
- Under Graphics Support, check the Disable Hardware Acceleration option.
- Apply settings and restart MasterCAM.
If you follow the steps above and still have strange graphics issues, you may need to tweak your video driver. On a number of PC’s which have Intel integrated graphics cards we had to roll back our drivers to a previous version to solve our video problems in MasterCAM.
