Hi everyone! Can you please give me some help? I am beginner/intermediate level and I need to replicate this structure for a project at uni. In grasshopper, I want to be able to regulate the height (H) of each section and therefore of the whole structure too.
Could anyone lay down the main steps to achieve this? Is there a tutorial you can share that teaches how to create a similar parametric structure that I can learn from?
Thanks a lot!
PS: I use Rhino8 and mac.
Something like Panelingtools can help: https://www.youtube.com/watch?v=jEsn12tqtkY
What happens when H gets longer?
does the geometry just scale/stretch? Or do the triangles remain as is and the connector bars just get longer? Or do the triangles rotate (which would limit the H distance but it’s still somewhat parametric_able)
Or what?
i would just draw one column with points and lines a to b. Then mirror it. Then copy that vertical portion you created and move it horizontally in the X to get the rest of the columns. Then You can boolean together the mirrored structures that touch.
since its a repetitive structure, you can just draw 1 column in gh then mirror and translate and bond at the connection points with a boolean join
like this
Thanks! I will take a look at these.
It is supposed to simulate a metamaterial. When H changes, all geometry/angles adapts by contracting/expanding, but only on that one axis. The idea is that it starts from a certain height H, then with pressure (as if someone steps over it) it will contract about 1cm. However, I want to propose a parametrization of the initial H, so it could start from any height desired then contract about H - 1cm. It will not be stretched over the initial H.
Ah oh, I think this is a good solution. And then to be able to reduce/increase H I can just use scale 1D?
yes or move your initial points
I assume (without knowing) that this is so supposed to be a linkages system, so the triangles remain, but also the vertical bars… But then the horizontal bars make no sense. So, no. 
It definately would be more interesting as a linkages system.
Forget paneling tools, etc. This is just a 2 dimensional array (tiling). Or a linear array of a linear array… Don’t know how important that the differentiation of the cells in the vertical direction is to you, but this can also be managed.
First work on how a cell responds to the changes of the bounds of a rectangle. You can worry about the rest later.
