I have a few objects I’m trying to prep for 3D printing. This one in particular is giving me a headache because I cannot make it watertight. I think its 95% of the way there. The first thing I did was explode it and SelBadObjects whereupon I found two problem areas. The first area I fixed with RebuildEdges, the second one, well, I tried a lot of things, and now it doesn’t appear as a bad object, but the whole model reads as an open polysurface. Here is the model in question after I messed with it quite a bit:
open_polysurface.3dm (1.8 MB)
Here is what I believe to be the problem area, right around this standoff:
Here it the model as I received it:
original_open_polysurface.3dm (2.5 MB)
Any and all advice much appreciated.
Happy New Year,
