[Plugin] Simple Catenary Curve
-
Hey REmus,
no need to be a Math Geek to find a use to it.
Anytime someone needs to model lets say the electric highvoltage cables supported by high voltage towers, this comes to a use.
Also for a more architecture realted topic, most of the Vaults designed by Antoni Gaudí's(the catalan architect author of the Sagrada familia in Barcelona)were actually inverted catenary curves, so anyone trying to model his buildings igh also find a use to it!
Thanks a lot! -
Hey, CADAddict:
Glad you mentioned Antonio Gaudi's Familia Sagrada, because that is the first thing I thought of when someone questioned the usefulness of catenary curves, besides suspended cables in equilibrium.

Remus's Catenary suspension bridge
taken in: Copy Array Along Path tool...have a look.(Catenary Curve for the general shape of the bridge. The ropes are handmade using Bezier Spline with only one intermediate point driven in order to simulate the weight of the rope.
A remark to Remus: Your Catenary Curve is made with only 16 segments. It's probably too few in many cases. It would be better to add the choice of this number(

Hey Remus:
Next step is "chain maker" or "rope maker"..
The first tool exists right now with courtesy of Chris Fullmer :[Plugin] Component Stringer

I think Remus is talking about a tool to simulate rope or chains - which is not what Chris' tool is doing.

)I'll have a look at it

Hi thomthom,
You are rigth! I had probably been taken by the hurry of enjoyment. Chris's "Component Stringer" is a very cool tool, but intending to do a different job.We can make a chain with it but it very uneasy and far from perfection!
@tig said:
Make half chain link (U) and use this tool then edit that chain and copy/hand the U geometry into an O loop of say 2.2 the original length, now you have your links; us 'make unique' on one of the links, edit it and rotate its contents 90 degrees. Select every other link and replace with this rotated one... a chain... done.
In such case, it will be better to do this way:
And for making a rope, I'm sure we can do a good job with our same Chris Fullmer's Shape Bender.

Hi Remus,
Something is wrong for me. "Simple Catenary Curve" opens and asks the number of segments (cool), but after validation, nothing happens..

Sorry, it was a silly bug as i was distracted while writing it last night. Hopefully this version should work.
-
Sorry Remus,
Something is still wrong!
The Catenary curve is drawn so small that I can't zoom on it.
I have reloaded your first one to experiment FredoScale Strech tool to figure out something like my suspension bridge's ropes.
seems not bad. I have no mathematic element to say if that remains a Catenary Curve.

No worries, i'll have a look at it this evening and see if i can get it back in working order again.

Hi REmus,
I just tryed your Tool "Simple Catenary Curve"
After the Dialog-box it seems that no Element was drawn.
where is the curve?

Uli, its always drawn at the origin...you may need to zoom in close.

Thank you for this plugin and also thank you for adding the explanation of what it is for and the Wikpedia link.
