@Charles_Cary  
Rhino does not make Hollow solids so to speak. I have run into this at least one time myself.  
Someone said also that you can make a small hole in the object and that is a pretty good work around.

Just one of the refs on the forum about this topic.

> Rhino doesn’t create “solids” per se. It is a surface modeller. So if you have your two spheres of different diameter, that’s all it needs to know. You can group or block them if you want to keep them together.
