How to tween curve between 2 curves along another curve´s specific points


I wanted to know if someone could help me solve this:

I have an arc which is divided into 4 points and i have a line that has a height (its coordinates are (0,0,20). The height of that line will progressively decrease until it reaches 0, each height progression will go to a specific point. I believe i have to apply tween curve but im not sure how to move those height progression to those points without actually using the “move” component. Also, i dont know how to create a progression that reaches the height 0. (Im attaching an image that i did manually in rhino)


You need at least two curves to tween, or are you trying to tween the lines?

Im trying to create what i made manually on rhino (the blue lines), but with gh. Is there a possibility with some other component to gradually scale them onto the points where the blue lines are?

Check out Pufferfish’s Tween Through Curves Along Curve component. About the zero length part, you should just make a curve that is small in tolerance (maybe 0.01 length). It will make things work better anyway. (8.7 KB)
