MultiCAD

MultiCAD is suitable for a variety of uses including architecture, chemistry, engineering and PCB design. Libraries of architectural, electrical and mechanical shapes are included with the package as well as primitives of common shapes. It makes use of a a massive 32,768 x 32,768 pixel screen and allows you to zoom in and out easily. What's more, the entire drawing can be printed out in sections ready to paste together. The program is capable of creating multi-layer drawings and will import and export CADja files. This version restricts the size of your drawings to 5K and brings up nagging messages frequently. Apart from that, it's a complete implementation.
