I would not be surprised at all. "Everyone" uses the Right-Hand Rule. Using your right-hand curl your fingers and point your thumb up. The thump is the positive direction of the axis and the fingers point in the positive direction of rotation.
They call it "right hand" but I think they (long-forgotten ancient mathematician) actually used the Earth as the convention for which way is positive and the fingers trick was discovered later by some math teacher. The convention is so that plants spin and their rotations around the sun go "forward" if you assume North is "up" Even wood screws are like this, turn then in the negative direction and they sink down into the wood. But rotate in positive direction if you unscrew them. I think students first learn this in trigonometry class in high school, then again in the first physics class then again [image: 220px-Right-hand_grip_rule.svg.png] (above from Wikipedia) On Sun, Jul 12, 2020 at 4:23 PM Gene Heskett <[email protected]> wrote: > Greetings all; > > My first foray into using polar co-ords to do a couple of bolt circles > worked well, but I was mildly surprised to find that an increased angle > went CCW around the circle on my GO704. > > Is this intentional?, or do I have something miss-configured? > > Thanks. > > Cheers, Gene Heskett > -- > "There are four boxes to be used in defense of liberty: > soap, ballot, jury, and ammo.
