Hi Michael.

With Orient command, at least I, I can't do what I want.
As it is difficult to explain, I am attaching a video that shows what I need to do.
All these questions that I ask are related to the exact mathematical method to make the clothespin spring, which seems to be very simple but has its complications, and it is essential to know exactly the tangent point of Helix with respect to the 2 points of the dock.
Because in order to have this spring manufactured, which for me only serves as an example, it must be completely delimited with respect to wood.

Cheers.
