how to orient diferent breeps according to one of his faces

Hi everybody

Firs of all thank you in advice for the help and sorry for my awful explication.

Im trying to reproduce the "magic ruler toy", which is composed by triangular breps that can be rotated 0, 90, 180 or 270 degrees.

Doing this doesn't represent a big deal. The problem comes when you want to orient each piece so at the end you finish with a continuous shape.

thanks again

thanks for the tip Igor

Ive been trying too apply to my concept but no way to solve it

should i use hoopsnake for each of the modifications that i do, first for the symmetry and finally for the rotation?

thanks again really helpful

amazing igor. lots of thanks

What i really would like to achieve is that i can control the rotation of each brep. so that i can control the final shape.
Also that the final shape wont overpass a matrix 5x6, where the length is the longest side of the triangle. This means that in this matrix you can inscribe 4 triangles.
i would really would like to understand the logic inside the hoopsnake component.
And also i should be able to see the different solutions while i rotate them

You can make your own list of angles and edit it while get the iterations "Step-by-step"(black arrow on the Hoopsnake panel).....and then make iterations automaticly....

hi igor

Heres where i reached so far.

What I'm trying to do is restrict the rotation of the breps inside a maximum volume so that they grow in the interior of the same. until here is ok.

The problem comes when I test the actual brep with the ones already rotated so that the brep doesn't overlap any of the breps already rotated. I must be doing something wrong win the logic.

All this is because i would like to do a form analysis where i could control maximum number of breps and maximum density, testing it with galapagos.

Again thank you for your support and sorry for my ignorance.
