Hello Michael,

I hope you are doing well.

I've got a quick question for you. Could we trust and assume a sealed joined surface object as a Solid one (A joined surface object without any open holes)?

And I noticed something! ( I had an object; Moi3D said it is a joined surface I saved the .3dm file as it was and opened it again now Moi3D says it is Solid) which of course is what I needed but it was kind of a surprise for me.
