Hey there,
I'm trying to make a catenary arch with a width and max height dimensions. I know this has been asked before but I havn't found any solutions yet.
from research the threads and links posted I'm concluding that:
1) y = a cosh (x/a) can't be balanced so only
a (catenary constant) is on one side
2) therefore Newton Iteration has to be used to find
aluckily from looking at Giulio's GH script from previous threads this has already been done in VB, and I hope he doesn't mind me posting his VB script here.
Only problem is, being useless in VB I don't know how to modify it so I can plug in a series of x pts and max height to get
a. Giulio's script solves the problem of the two ends of the catenary curve not being on the same horizontal plane and not max height.
anyone can give me some pointers?
Thanks :)
links to catenary and Newton, also same problem being solved in Revit:

a as input and gives max height in a panel.
