I’m a Mac Rhino 5 user having some trouble with boolean unions. My objective is to get a closed polysurface of a cage-like icosahedron built with round cap pipes for 3D printing. Here’s the file: Icosahedron.3dm (3.1 MB)
Methods I’ve tried:
-Checking for surfaces and naked edges (none was found)
-Adjusting tolerance (and here I found something interesting: sometimes running the intersection command under tight tolerance and then splitting under lower tolerance work out for splits that fail at tight tolerance)
-Intersecting + Splitting + Joining
-Exploding all shapes and joining until it works (this ogre method was the only way I got a final solid that was, unfortunately and obviously, an opened polysurface)
I would like to know if any of you would have any thoughts or ideas I could try.
