[Closed] Catenary Curves?

fair enough. its just figuring out how to get the bezier handles to position correctly to that of duplicating the Catenary.

It would be nice to have the ability to choose the start and end points of a line and then a spinner to adjust the sag/rope weight.

where does weight comes in?

Diagram of forces acting on a segment of a catenary from c to r. The forces are the tension T0 at c, the tension T at r, and the weight of the chain (0, −λgs). Since the chain is at rest the sum of these forces must be zero.

I’m just trying to think of the workflow of using a catenary line in 3d.

in your case only length of chain (rope, etc.) make sense.

The parametric form of the catnernary is easier to work with…it needs only one variable…

it needs one variable and one constant.
x(t) = aln(t)
y(t) = a/2
(t + 1/t)

Next youll be making minimum energy surfaces.
