If all displayed values in Rhino would round down to the document tolerance, this wouldn’t be an issue we’d ever see, right?
But yes, setting a generated mesh tolerance globally seems like a good thing in this case, because I still don’t understand if the templates which ship with Rhino use weird settings or why I constantly get “not accurate enough” meshes for my tastes…
When I can’t get G1 or G2 where I want it, I often zoom in ridiculusly high, and it’s funny to see how many meshes (imported or otherwise) have “huge” gaps in between them which still fall below the document tolerance so Rhino (mostly) doesn’t care.
