Folding structure

[w1743763]

Hi all!
getting there att.gh (50.8 KB)

What would be the best was to open and close these umbrella-like structures that are controlled by the sun or an attractor point? I want the initial point to stay at the same height but need the scale NU x and y to change I think but cannot quite manage to do that with an attractor, if anyone cant point a finger in the right direction it is much appreciated

Umbrella folding system

Hi I hate to ask for help but I’ve been stuck for hours now, I am trying to achieve an umbrella-like structure to open and close at each endpoint and midpoint, Ive managed to connect the endpoints but cannot seem to connect the midpointsThe black lines show the ones I’ve already connected while the red shows the one uve been unsuccessful with, I am also trying to figure out how it would fold, Any kind of help is appreciated [connection] New Scipt.gh (33.9 KB)

Hello @w1743763,

@w1743763

That’s totally up to you! Here’s an example with a curve attractor. Umbrellas close to the curve are more closed than others that a further away. This behavior can also be quite easily inverted.

I want the initial point to stay at the same height but need the scale NU x and y to change I think but cannot quite manage to do that with an attractor,

In my example, the rod lengths stay constant. The trick is to rotate each individual edge, rather then scaling them non-uniformly.

(This is also animated! Click it, if it doesn’t auto-play.)

Hope this helps! And for the future, please don’t create more than one thread for the same thing.

This is so great thank you so much and thanks to everyone helping me! I am so close to getting where I want to be with the script, the last thing I am trying to do is apply this to a non-planar surface, to line up with a different script.

I just need each “umbrella” to rotate not on the z-axis but according to the center curve. As noted on the script, MCneel forum help.gh (187.4 KB)
