How to find the point on a curve that being nearest to a plane ?

Hi,

now i have a plane, and a curve, i want to find the nearest point on the curve to the plane, how can i do it?

i think i can first project the curve on the plane, and then find the nearest path line between the original curve and the projected curve, but how to find this line?

Curve>Analysis>Extremes

Takes a curve and a plane as input

The L output is the closest point on the curve to the plane

oh, yes! I ignored this nice component :-)

Thank you for reminding, Daniel!

Hey Daniel,

Do you know who is more precisely? I baked the curve and the plane in my example (see the file I posted). If I use the CrvDeviation command in Rhino the result is not the same as the baked result from the Extremes component. they differ : 3.15992e-07 meters

now! I guess it has to do with iterationsteps. But which one is the better result?

Best Regards
