Dear Roger,

The assumption of the fact that P1,P2,R1 and R2 are in one plane is correct, because is is about muscle wrapping, and the muscles do not wrap around the whole cylinder, but only have real small part arc length on the cylinder its self. I tried to understand your explanation further, but I must admit, that it is too difficult for me. The dx, dy, dz....are that the distances between R1 and R2? But I do not have R1 and R2, I want to calculate them. The only distance I know on forehand is the distance between P1 and P2, and the position and direction of the axis of the cylinder. 

Hope I do not frustrate you, because I do appriciate your help very much. So thanks again a lot.

Best Wishes,

Els
