Vector based images can be manipulted in CAD programs while rastor based images cannot. For this reason, we recommend using a digitizer to input hard copy patterns into the computer. It is possible to digitize patterns in sections and then paste them together in Symmetry. I installed my digitizer, but the puck won't work. Although it is possible that the puck is defective, you probably have a driver conflict.
Digitizers just work.
You plug them in, turn them on, and use them. Although this sounds like a drastic solution, it is a simple process and will result in a clean, faster functioning computer.
