What is the easiest way to count the revolutions of a spinning coordinate system?

I have found a simple workaround.
1. Connect to the coordinate system to be observed a belt constraint with a transmission ratio of 0.0001 or even smaller, depends on the revolutions you want to count.
2. Divide the angle on the large belt wheel by the transmission ratio and again by 360 degrees.
3. If necessary, subtract the starting angle of the coordinate system so that the counter starts at 0.
4. If you still want to delete the units, you can extend the formula with "/ deg".

Choose a gear transmission (Spur Gear) instead of a belt transmission, because strange effects (slip?) can occur with belts. Wink
