Hi all,

I've found a handful of threads that describe how to either:

1) Pack circles of fixed radii so they're tangent but aren't contained within a boundary

2) Pack circles of varying radii within a boundary so they're actually tangent

OR

3) Pack circles of fixed radii within a boundary so they're nearby, but not actually tangent

However, for my purposes I need a definition that allows me to set discrete radii, pack circles that are actually tangent AND have all the circles contained by a boundary.

Using Kangaroo like in this example has gotten me closest to my goal, but I still haven't been able to constrain the circles to any boundary:

Here's the slight adaptation of the definition explained by the link above that I'm working with:

Circle%20Packing%20Kangaroo.gh

I'd like the rectangle grouped at the beginning of the definition to act as a container for all the packed circles.

Any help anyone's willing to offer would be hugely appreciated- thanks in advance!
