How to locate the farthest point on a curve along an axis

Given the lack of the Point - Intersect Curve and Tangent tool

Actually we discussed this in this topic:

Tangent on Spline Tool

I know… this was meant as a sketch. not as a precise drawing. I didn’t feel like going back and forth by .05 to put it on the line. Not to mention the curve could be quite different than what I drew. At this point - since there is no tool defined - we can do what ever we want. Me… I would just find all tangents, create a drop list that you could select from. Actually it’s the same sort of issue we have with the Intersect Curve & Axis, where we can only get the 1st inter…

And there is an existing Github feature request issue … albeit called Point : tangent spline & line. Technically there could be 2 tools… and Intersect Curve and Tangent, and Intersect Spline and Tangent. The curve intersect realtively easy to solve as there is only 1 solution vs multiple possible solutions as I pointed out in the other topic.

That being said I think your solution is close enough. Especially given the fact that some tools have an accuracy of 1 mm… such as the Point On Curve, where the point can’t get any closer to the start or end point than 1mm. Even given a much smaller value… 0.0393781in = 1mm:
