figured out already. Need to defind, the right tool and radius.

Why in simulator it show at the wall with an angle, but not by insert radius? Does anybody knows how to fix this bug? 2023vers

Methods 2: why my mastercam still working with two graphics are running. Because your Nvidia latest newest version auto updated not stable. Uninstall then reinstall with the previous Old version that are stable. If you can't find old version AT NVIDIA WEB. Well go to your pc/laptop brand provider, go to their website support then install the stable version. I have dell as you picture below. After reinstalled stable version of Nvidia card that you have. Follow my picture below, to setup Nvidia settings.

Ok both graphic are in used. Turn off one.

I just figured out. Open your computer management, go to Device Manager, then open tab display adapters. Method 1; IF YOU SEE TWO GRAPHICS CARD ARE RUNNING, THAN YOU GOT DISABLE ONE or the Other. Also try to figure out which graphic work for you. BOTH CAN'T RUN together it fighting with each other. Let me know if this solve at your end.
