Catenary - script for shape of a flexible chain suspended by its ends

I did a script for shape of a perfectly flexible chain suspended by its ends

Are you going to make the beautiful arched wooden bridge ,kintaikyou?

Hey, thatâ€™s awesome! They used something like that in elephants dream, as I recall.

Will this be included in the script for Helix and spiral ?

New features

• Now work with x,y,z coordinates
• You can select two objects and push GetPos to draw up the curve among them
Look firts post
RJ2005: No, is a different script

I think I can use this. Does it give you the shape alone, or build the links of the chain between the two end links?

Fantastique

I donâ€™t know how you did this catenary?
i did it in Xcell and itâ€™s not easy to get proper results - Iterative calculation for hanging rope or cables.

with the catenary the parabola would go very well - just a tough
With this you could make Simple parabola - Arch - Dome ectâ€¦

Do you expect to put other new features and which one?

Ok i think you did it for an unloaded chain - Load uniform / distributed or not?

When you say select two object it would use the center wherever it is located for each objects !

hi alex! another good script!

saludos

Thanks alexvâ€¦for another cool scriptâ€¦

Dear Brother
i am using winrar to extact the file.

Are you using winzip or 7zip, winrar works fine.
m.a.

Hello, sorry to bump a thread from over a decade ago but this script looks really useful, does anyone know of an implementation of something similar for blender 2.8?

Nice. There have been a few times when I could have used a catenary profile, such as for a hanging chain.

I havenâ€™t seen anything, but if you plug this formula into a z function surface generator (found in the included add extras mesh addon) you can generate the curve:

a*cosh(x/a)

adjust the value in a to change the shape of the curve:

A little less user friendly, but at least itâ€™s something.

just a note here
this general equation does not tell you the real shape it is only an approximation

to get the real values you need the real physical parameters for a chain or a cable!

happy bl

hi, Catenary function is in the add curve extra objects addon in 2.79 and 2.8.
Thanks for looking.
