Hi OSTexo, well a helix is a pretty linear progressing thing, generally I think linear reasoning should work with it.

The way I'd do it, is that you want to measure the angle that your red point has traveled along the helix, so you want to use the longer angle of 288.0962488 degrees, not just the smallest angle between them.

So at this angular travel station of 288.0962488 degrees, your point has traveled a distance in Z of 2.4351833 . To get the pitch you want the distance that will be traveled at a full 360 degrees, so the conversion factor is 360.0 / 288.0962488 - multiple the current distance of 2.4351833 by that conversion factor to get the pitch:


360 / 288.0962488 * 2.4351833 = 3.042962


Does that work to get you the proper pitch?
