algorithmic modeling for Rhino

merge/union on multiple surfaces

I have a grid of circles, and I offset a smaller circle from each circle. Grafting the two boundaries, I create a set of surfaces using boundary surface. I am now struggling on how to make all of these a single surface so that I can extrude it into a solid.

What do you think is the best course of action? Any suggestions very much appreciated, thank you so much.

PS: I don't think solid union on all the produced solids is a good idea (too expensive computing wise), and solid union says that the boolean set is empty (probably due to overlappign surfaces)

Good to see various solutions, guys.

As Tom said, splitting and creatiing surface in Rhino is much faster.

One thing to clarify is that there are some self-intersecting curves created using Tom's code.

These seem to interfere with creating boundary surfaces. By removing them, might be able to create boundary surfaces in GH too.
