Fill an rectangular area with predefined elements

Hello dear grasshopper users,

I am currently working on a large scale facade and would like to solve the following problem:

let’s say I have defined a number of rectangular shaped blocks, in this case I have seven ,shaped like shown in the attached picture (1:1, 2:1, 1:2, )
Now I would like grasshopper to automatically create a random pattern which would fill out the large rectangle (In this case 17m X 110).
Is there already such a thing? I did not find something yet, I think I remember that David Rutten has worked a lot on this kind of problems…
I would be very thankful If someone can give me a hand here…

best regards


… here is a version I made by hand, to illustrate the direction I am aiming…

and here is a build example that was my initial inspiration…

I think there are lot of discussions and examples on grasshopper forum.

Search, packing nesting, rectangle, uneven subdivision …

On your example I don’t understand how to fill 17 m with 6, 3, 1.5 ?

You could also use Substrate component from Grasshopper, but it will generate random rectangle. You will have to put angles to 0.

I add some difficulties to resist, as I prefer old Grasshopper forum I did an example of what you want, not exactly but it could be corrected.

You need anemone plugin, Human is not necessary just to draw black lines.
Have fun.
