How to generate random array

Please login with a confirmed email address before reporting spam

Hi,

I have a model that I would like to use the array command to generate same structure in the model. However, array command gives equal distances between the structures but I would like to place the structures randomly in the space. Any way to do that faster than placing one by one?

Thank you in advance

There are several possibilities.

One, very lightweight method, is shown in the attached screenshot: Use a Copy node referencing a random function.

A more sophisticated variant, using a model method, is described in this blog post:

An important thing to consider, is whether it is a problem or not if the generated objects overlap.
