Thanks! I haven’t gotten a chance yet to really look at the link but it seems very interesting. And there also is a close-packing plug-in into Rhino that has 4 different algorithms that I’m going to start using ( I just found it yesterday: http://en.wiki.mcneel.com/default.aspx/McNeel/2dcirclepacking). I think that it makes more sense at this point for me to study and utilize these existing sources rather than spend my semester generating my own. Thanks again, sabrina
