This operator is used to determine the relationship between the 3D bounding boxes of two sfmesh, meshgeom, or box3d objects. If the 3D bounding box of object A is fully contained in the 3D bounding box of object B, true is returned. If the 3D bounding box of object A is not fully contained in the 3D bounding box of object B, false is returned. Examp...
