Hello
I don’t think the screen shot you use helps answering your question. It just show that you have a pirated :pirate_flag: version of Rhinoceros !
you can measure each object, take the maximum size, create a grid and then place the objects.

You can also use OpenNest to nest object on a rectangle.

if you really need a grid, my plugin Nautilus has 2 component to do that

And last advice, read that
