The volume of the attached closed solid polysurface cannot be calculated, yet it is not caught as a “Bad object”.
To me, this should qualify as “Bad”. At least, it would allow me to identify it before I try to feed it to the Grasshopper for processing.
I agree that for one of the faces, the holes tangent to the edges are nor a good idea if you want to keep out of trouble, but I have a boatload of other similar solids for which the volume was calculated without issue.
