I'm trying to use geometry nodes to create a support system for 3D printing with a thin wall as the connection point:
What I want to do is have columns going from the B points down to the floor at Global Z=0.
What I'm trying to do is make the columns with instanced Curve Lines, that I can give a round profile later for thickness. The B points are not actually there. The original Points on the curve are 'A' and I instanced the Cones there and moved them in their Z direction down by the height of the the curve profile 'h' and the height of the cones 'H'.
I used the offset of the Cones as the starting point of the Curve Line but I have no idea how to set the coordinates of the End point to be at Global Z=0 (C points). Is there a way to do so? (I don't know if this would be the best method to begin with, I'm fine with doing it differently too).
I would also want to later Instance the base of the supports on the C points (A Cone Primitive would work, rather than that object specifically)
