PartWorks is a CAD/CAM program that will get you started quickly designing for CNC cutting and machining.
In addition to doing great cutting of 2D parts, PartWorks has excellent capabilities for 3D V-Carving (machining that gives letters and shapes a chiseled look; also referred to as Intaglio or 3D Engrave). It allows anyone with a ShopBot CNC tool to quickly and easily incorporate beautiful, decorative carved designs into their own products.
PartWorks comes with the ability to V-carve any fonts on your computer as well as closed shapes. It also includes advanced machining strategies for large areas and difficult to machine patterns.
