Hi!

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)

Thanks!
