Calibrate Tablet asks you to digitize two known locations in the real area. The two selected points tell CC3 how to scale the coordinate system in the real digitizing area.
To calibrate your tablet, select [Tablet > Calibrate]:
1. Select a first reference point on the tablet’s real digitizing area, then enter its (x,y) coordinates via the keyboard.
2. Select a second reference point on the tablet’s real digitizing area, then enter its (x,y) coordinates via the keyboard.
Pick two known points that are not close on the surface of the tablet, and not orthogonal (horizontal or vertical) to each other. Points far apart and nearly a 45° bearing to each other will give the best results.
You need to re-calibrate the tablet each time you trace something that is scaled differently from your current configuration. You do not need to reconfigure unless you change the size of the real digitizing area.
