TANGENCY for the INTERSECTION of 2 curves, not just a point on one curve

[Proterio]

Well that was my original idea, but this is an attempt to solve this problem:

Curve through points tangent to two circles...how?

fwiw steve, i do realize there’s an exact point which you’re looking for and it appears as if interpCrv could find that point… mathematically, it’s beyond me… because as next point is being moved into place, the back end of the curve is also adjusting and/or somewhat free to move around (which doesn’t happen with an arc or line since they’re much more limited in their definitions and a lot easier ,for me personally, to understand the formulas behind them)… but in this video, (or better yet, ju…
