Hello all - I am having some issues with a house model that one party did some work on across the country, then emailed over to me. In trying to separate the model out into groups and layers off of “Layer 0” there appears to be missing geometry (i.e. the walls are not complete solids, rather many are just faces with texture applied to them, or some faces are missing.) I am having to painstakingly remodel each portion of the house to reestablish the solid walls, floors, etc.
Wondering if this might be a corrupt file? Or just sloppy modeling? Untimately hoping there might be an extension that could help form solids out of the broken geometry. Screenshot attached.
