Do I need a CAD program for MeshCAM Art

MeshCAM Art allows you to build complex 3D reliefs from simple 2D artwork. You do not need a CAD program but you will need the source artwork to start with. A vector-based program is generally better but raster programs are also fine. The following programs are recommended:

Vector

Corel Draw Adobe Illustrator Inkscape (Totally free)

Raster

Paint.net (Totally free and really good) Adobe Photoshop
