I have a project where we have multiple catenary curves between two points which do not produce the lowest point (sag point). However, in order to calculate the reactions of the forces on each catenary, we need this point known.

Extend curve unfortunately does not have a catenary option and so I have been working to calculate this sag point but have been met with some resistance. I have scoured the net and various civil engineering and geometry books but many do not have a formula for finding the sag.

I have reviewed all the related grasshopper forum questions to develop my own catenary script (for my own understanding but entending this to produce a completed â€śidealizedâ€ť catenary for purposes of the reactions has evaded me. If anyone has any suggestions. Let me know.

Much appreciated
