I'm not angry. Mildly amused is more like it. And I don't see where I've insulted you at all. A fact is a fact. You do not have enough experience to make the statements you've made about ArtCAM. Considering your problems are self inflicted you would have the same problems with any CAM software. Your vectors "need" to be closed with no loops. I've asked direct questions and requested a sample or some type of file related to your problem. And all you've done is accuse me of hurting your feelings. Welcome to the shop floor. Where work gets done and problems get solved. You want a hug and a kiss on the cheek? Go see the receptionist. Post the file and I'll show you how to fix it. End of story.
