Guessing verson of Artcam supplied may not be 100% manufacturer, Delcam , approved as full version is well over thousand pounds...

Artcam is very much a 3D program , great for cutting reliefs and signs , not ideal for cutting things like brackets.

Cambam has a free old version and a free trial of the most recent version,it handles 2D and 2.5D better than a 3D program.
