Enjoyed a lot following your tips and organization. It was very well explained indeed! I dared to try it, specially because you choose to teach a single module of it. Now i'll try to replicate. Thanks!
First you have to put the triangular surface in the final vertical position, with the hypothenusa vertical in the center (8.5*.5*1.4142) with the two cathetos of 8.5/2 and a 90 degrees angle. Drawing the lines that join the correspondant vertices, you will have the movement guides... I changed panel values using the same Grasshopper program. Knowing the final position of the triangle, you have the correct values of the panels. 0.1464 (it does it all) 6.010 (center point) 3.005 (lower left point) 0.9999 (slider point)
Hi, to avoid the error when bringing the Does It All slider to 0, we need to work on the vertical Plane we created for the mirror, so that we don't end up with two points at the same place when we bring the slider at 0, and lose the mirrored geometry. We can just use a simple Addition component, plug it into the C input of the Plane 3pt node, and in the first input of the Addtion component we plug the raised center point, and in the second input we plug a value of {0,0,0.1}, the actual value of the z is not important as long as it's greater than 0.
how did you calculate how far your moving points of the first triangle would go? i realise they need to be in relation to keep the shape of the triangle during the movement, so these values need to be predetermined
I agree with this.

Thanks for the tutorial. I got an idea to work based on your tutorial where my pieces fold similar to your. But I was wondering if you could help me figure out a way to make a grid out of the system where several pieces could fold at the same time and contract toward a point; not contract in their own space.
Thank you so much for the tutorial. I just have a question though, the triangle actually transforms as the centre point raises up, as the domain for the lower left point has been set up as 0~5, which is approximate value. I was wondering how we could possibly set the definition to keep the shape the same when it moves, just like the real origami works..

It was the most valuable grasshopper tips I 've ever seen! Thanks so much
Thanks so much for giving this tutorial that helps me a lot!
Great to hear! Thank you for your comment.
Thank you so much for this detailed and patient explanation
Inbar Shahak you’re welcome! Thank you for the comment and feedback.

Besides how do I keep control of the slider and Geometry if I bake the Polar Array?
Once you bake it you won’t have control over it anymore.
What if i want to move one corner of the structure? lets say 2 to go up 1 inch vertical?
how to develop the kresling pattern using it?
Hi. Did you figure this out?
Thank you so much for the tutorial. I just have a question though, the triangle actually transforms as the centre point raises up, as the domain for the lower left point has been set up as 0~5, which is approximate value.

I'm quite sure this definition dont preserve the shape of the triangles, so basically it won't make a developable surface
Can you learn us about origami in grasshoppher
nahed ta Yes I plan on making a Origami Tutorial. I might use the Kangaroo plug in for Grasshopper to explore the topic.
Thank yoooou 😀
At any time the lesson will be presented?
I'm so excited
