No Problem, Functional gears are really an advanced topic so it isn't explained very well, when in doubt, ask..I know the fool that coded them. :)

That's what I was missing. Thank you.

Hi:

The functional gears are set by ratio, so if you enter 0,1 , it means a drive ration of 1:1 at angle zero. A 45, 2 would mean the drive ratio at 45 degrees is 2:1 ..etc..  If you use a formula, the formula describes the drive ratio formula.

  Your not setting a distance, your setting only the ratio, the distance is a function of the module of the gear which
sets the 1:1 distance of the two centroids.


Thx

Functional Gears - Polar Coordinates

I'm slightly confused with the results of polar coordinates used by functional gears.

The following points(in degrees, distance) should result in one point directly above the other.
0,1
45,1.414

However, the second point is not placed as expected. With an imaginary triangle, two sides have distance 1, the third should be root 2. But, the functional gears tool does not place this point like that. What am I missing?
