I have gone back and re-read these two issues of Tips. I think I know where the problem came from.
bjbethke mentioned scanning the grips I have.
These have checkering and a logo that I would want to delete. I need to figure out how to edit them out and create a smooth domed surface. I guess it's time to experiment more with the pattern editor or is this something that can be done with the probe software?
I am going to build a scanning sled and see what I can do.
