At that page and more in particular in this page it links to:
I see no mention of the Mesh Repair wizard.
Both pages are IMO rather unstructured in information and lack readability.
They are - I think - quite old and could use quite a few additions
The http://wiki.mcneel.com/rhino/faqclosedsolids immediately mentions STL files
yet that is merely a sub-topic of Solids in general. This page http://wiki.mcneel.com/rhino/soliddiscussion
would be more of a faqsolids.
I know resources are not abundant but a good updated writing on Rhino’s concept of solids and the subsequent issues with exporting 3D printing and other related information would be good to have.
- solid editing tools
- mesh repairing
- exporting to various “solid” formats
During my teaching I found this (solid vs surface) to be an issue that always needed to be cleared at one point or another.
