Don't use boxes, use facets instead, they let you create arbitrary triangular mesh (and are better supported anyway). See scripts/test/gts-horse.py (for import from gts), examples/mill.py (for explicit construction of the surface from individual triangles), examples/STLImportTest.py (import of the mesh from STL file), examples/cyl.py (triangulating polylines in space).
Also see documentation at http://beta.arcig.cz/~eudoxos/yade/epydoc/, notably the module yade.pack and functions gtsSurface2Facets <http://beta.arcig.cz/%7Eeudoxos/yade/epydoc/yade.pack-module.html#gtsSurface2Facets>, sweptPolylines2gtsSurface <http://beta.arcig.cz/%7Eeudoxos/yade/epydoc/yade.pack-module.html#sweptPolylines2gtsSurface> and revolutionSurfaceMeridians <http://beta.arcig.cz/%7Eeudoxos/yade/epydoc/yade.pack-module.html#revolutionSurfaceMeridians> (which you might use for complex tunnel shape).
