I am trying to model a translation scissor system in a hexa grid array. I tried certain methods, with the exceptions of the use of trigonometric as I couldn’t manage to find sufficient data that would help me do it ( and I am still learning to model using trigonometric equations ). with my latest attempt, I tried rotating the bars at the midpoint of a line. Although it seems to be “do-able” this way, it wouldn’t let me simulate the deployability. hexa.gh
Could anybody suggest me a proper way to do it than what I have already attempted?
It looks like you’ve spent quite a lot of time trying to figure this out.
You’re correct in thinking that trigonometry is one good way to do it - Attached.
Using weaverbird is optional - it’s a quick way to set up the grid.
A variation of this definition also works for making a hoberman sphere

Thx, just what I was looking for.
Do you know by chance if there any way to create the pipes so that they don’t intersect one with another ?
