I was asked by a few to produce some demos showing the table setup and some selections on the software
for tracing

http://youtu.be/IddM_NwSkm8 setting up tablet works and the cnc draw program

http://youtu.be/qRYEUQIq3vw tracing through curves and points a guitar profile

http://youtu.be/coVxfoOs4q0 tracing out a guitar profile using lines and arcs selection

I hope this helps ,it just takes a few trys to get good at the tracing
