Never knew that. Thanks I haven't worked much with machine simulation. Wish it was an option in verify or backploat

Turn profile slice works great for generating profiles on mill or wire parts too just need to set a quick plane to your depth and do a turn profile slice with both profiles like i did in the wire edm application shown below. Of course there is other ways to generate that profile easily too but that tool is more powerful than just lathe work. sometimes i like just having a profile for like a swarf or a wire 4axis path using the Sync By Branch sync method and projecting lines or turn profile slice creates that geometry easily.

Well, your system specs definitely meet the minimum! Just to eliminate a faulty graphics driver, press the windows key/start button and scroll through your applications list until you find the Mastercam 2018 Demo folder. Click on "Advanced Configuration" and choose "Graphics support." Whatever the Hardware acceleration option currently is, switch to the opposite (i.e., disable it if it's enabled and disable if it's currently enabled). Then try to run Mastercam again and see if it still hangs on the startup tasks portion.

I need a full list of services... traveling a lot more lately.

...and 2 of them are selling his services.
