"FACTS"? Like the FACT that your "problem" with mask on arc was completely self inflicted?
The FACT that you signed up a fake name on emastercam so you could complain about Mastercam's inability to machine an open pocket, only to be quickly rebuffed by people who actually know what they are doing?
The FACT is that you are utterly helpless on virtually every aspect of Mastercam.
If you spent 1/10th the time using and learning the software, as you do complaining about it, you wouldn't have nearly so many complaints. Then again, you are not even remotely sane, so who knows what would happen.
