Ahh ... ok, so you're an instructor or professor?
What's your design work-flow?
Does your stylus rotate infinitely?
Exactly which MicroScan unit do you use?
How accurate is it?
What have you used it for?
Mine is a G2XL (66" x 6DOF). Tolerance not yet determined (still working on a usable fixture to do it) Got the unit used. Using Rhino 5 on Win7x64
CADpad is part of the latest and greatest MUS.
I'm still learning how to use it w/Rhino.
Not sure if the MUS gives Rhino any extra commands or abilities?
I found this in the Rhino 5 Help on ball tips:
Using a non-standard tip with the MicroScribe
If you use the MicroScribe and Rhino with tips other than the standard tip that comes with the MicroScribe, you must edit the mstip.dat file and follow these instructions, which are also contained in the mstip.dat.
Set the MicroScribe to use a non-standard tip
A Standard Ball Tip is 0.242 inches shorter than standard point tip.
Set D5Delta = 0.0 if using standard point tip.
Set D5Delta = 0.242 if using standard ball tip.
If you have a non-standard tip, measure the exact difference between the standard point tip and your tip (in inches) and type that number for D5Delta. If the tip is longer, make D5Delta negative; if the tip is shorter, make D5Delta positive.
Note: Be sure to power up the MicroScribe with the standard point tip in the home position (inserted in the stylus holder) before changing tips. Powering up the MicroScribe with anything other that the standard point tip will cause inaccuracies in the data Rhino reports.
However, I could not find any file on my computer called "mstip.dat".
