Digitizing Tablet Support in Rhino?

AutoCad has a Tablet command to calibrate your stylus and tablet, without that the stylus isn’t accurate, you get ovals instead of circles, for example.

I can’t find anything like that in Rhino, am I just missing it?

Nothing like that in Rhino.
For actually digitizing drawings or images, we use Picture/PictureFrame command, and scale it up to real size.

Ah, okay. Yeah I just use it to trace weird parts. Thanks.
