Isocurves at specific Z coordinates

Hi McKinnley, I think I would use the Line/Plane intersection (PLX in tab intersect>mathematical). The line input takes your line, the Plane input takes the domes isocurves in {u} direction. The found points are the centerpoints of the circles around your line.

Hey Pieter!

Thanks for the reply. Do you know if why I am not getting points at each of the intersection point with the defn?

if you do it that way, I would just use the planes to intersect with the line, the Iocurves component is superfluous in that case.
In my definition I did something else though, hope it helps.

Okay. That makes sense. One more question about your defn. Why did you need to graft the closed planar curves to make them make them periodic curves? And also, how in the world does the plane|line intersection component take a closed curve from the isocurve and accept it into its plane input?

 

Thank you again.

You're welcome McKinnley. I've got two answers to your one more question;)

I grafted the two lists to create 'couples' of the curves that are in the same plane.
And if the closed curve is a circle, the Plane input recognises the plane the planar curve is in. Works with rectangle and closed planar polyline too.
