Generating rectangle from a center point instead of a corner point while controlling distance between each rectangle

[serabouch]

hi,

I am trying to generate an array of panels from a center point. I have found a way to do this by using a rectangular grid by using the following script:

This creates a grid of rectangle from a centre point as such:

In this case it works fine. However i want to make panels out of the grid and control the distance between the panels. I managed to do this with the following code:

This allows me to generate panels from a grid and allows me to control the size of the panels as well as the distance between them as such:

In this case however, the grid starts from a corner point. What i want is the grid to start from a center point as the first example. When i try to combine both codes it works somewhat but the panels dont seem to start from a center point (in this case (0, 0). Any idea how to solve this?

Hi @serabouch,

I guess something like this would be an overall more practical approach:

First you draw a regular rectangle grid, then you introduce the cell spacing, and after that you move the grid cells back to the origin (cf. green dot).

Hope this helps!

Yup this is exactly it. Ill spend time and try to understand exactly how this works. Thanks a lot!
