hello community, my level of gh is not so good but i was trying to solve this problem since a bit of time and nothing worked. I am trying to design triangular windows which angle changes following a curve, my idea was to start with 3 points to form a triangle and one point’s height changes ( ranging from 1 to 1000) 3 points.gh (24.1 KB) essaie.3dm (39.3 KB) and then link the points and extrude them to surfaces. i tried crating a surface and changing th height if the joint line and parametrize it to change according to curve attractors didnt work either. i will share my files gere and apprectiate if anyone point what am doing wrong thanks in advance
Two Curve params in your file are not initialized:
In both cases however, it appears to me that the peak of the “triangle” has already been established by the Move component (green) whose output is used by two Line components.

Check this also give you an idea how to use attractor, you find two solutions one with regular components and one with Heteroptera addon

that is exactly it, i just needed to reverse the domain parameters it works perfectly. thanks a lot for your help, i will study and learn from your code because some components are new to me 
thanks khaled for your reply, i appreciate your help. i have a question though, i cant find how to control the number of the y axes elements and if i insert the length i need it doesn’t match the real value i need. if i need the points to be repeated x times on the y axes with a distance of 4200 for exemple.
D for distance and N for the number of repeats
