You can dump the TopoDS content to a string using the pickle module: >>> import pickle >>> from OCC.BRepPrimAPI import * >>> my_box = BRepPrimAPI_MakeBox(10,20,30).Shape() >>> box_dump_string = pickle.dumps(box1) >>> print box_dump_string And you should get something like: ccopy_reg _reconstructor p0 (cOCC.TopoDS TopoDS_Shape p1 c__builtin__ object p2 Ntp3 Rp4 (S'\nCASCADE Topology V1, (c) Matra-Datavision\nLocations 0\nCurve2ds 24\n1 0 0 1 0 \n1 0 0 1 0 \n1 30 0 0 -1 \n1 0 0 0 1 \n1 0 -20 1 0 \n1 0 0 1 0 \n1 0 0 0 -1 \n1 0 0 0 1 \n1 0 0 1 0 \n1 0 10 1 0 \n1 30 0 0 -1 \n1 10 0 0 1 \n1 0 -20 1 0 \n1 0 10 1 0 \n1 0 0 0 -1 \n1 10 0 0 1 \n1 0 0 0 1 \n1 0 0 1 0 \n1 30 0 0 1 \n1 0 0 1 0 \n1 0 0 0 1 \n1 0 20 1 0 \n1 30 0 0 1 \n1 0 20 1 0 \nCurves 12\n1 0 0 0 0 0 1 \n1 0 0 30 -0 1 0 \n1 0 20 0 0 0 1 \n1 0 0 0 -0 1 0 \n1 10 0 0 0 0 1 \n1 10 0 30 0 1 0 \n1 10 20 0 0 0 1 \n1 10 0 0 -0 1 0 \n1 0 0 0 1 0 -0 \n1 0 0 30 1 0 -0 \n1 0 20 0 1 0 -0 \n1 0 20 30 1 0 -0 \nPolygon3D 0\nPolygonOnTriangulations 0\nSurfaces 6\n1 0 0 0 1 0 -0 0 0 1 0 -1 0 \n1 0 0 0 -0 1 0 0 0 1 1 0 -0 \n1 0 0 30 0 0 1 1 0 -0 -0 1 0 \n1 0 20 0 -0 1 0 0 0 1 1 0 -0 \n1 0 0 0 0 0 1 1 0 -0 -0 1 0 \n1 10 0 0 1 0 -0 0 0 1 0 -1 0 \nTriangulations 0\n\nTShapes 34\nVe\n1e-07\n0 0 30\n0 0\n\n0101101\n*\nVe\n1e-07\n0 0 0\n0 0\n\n0101101\n*\nEd\n 1e-07 1 1 0\n1 1 0 0 30\n2 1 1 0 0 30\n2 2 2 0 0 30\n0\n\n0101000\n-34 0 +33 0 *\nVe\n1e-07\n0 20 30\n0 0\n\n0101101\n*\nEd\n 1e-07 1 1 0\n1 2 0 0 20\n2 3 1 0 0 20\n2 4 3 0 0 20\n0\n\n0101000\n-31 0 +34 0 *\nVe\n1e-07\n0 20 0\n0 0\n\n0101101\n*\nEd\n 1e-07 1 1 0\n1 3 0 0 30\n2 5 1 0 0 30\n2 6 4 0 0 30\n0\n\n0101000\n-31 0 +29 0 *\nEd\n 1e-07 1 1 0\n1 4 0 0 20\n2 7 1 0 0 20\n2 8 5 0 0 20\n0\n\n0101000\n-29 0 +33 0 *\nWi\n\n0101000\n-32 0 -30 0 +28 0 +27 0 *\nFa\n0 1e-07 1 0\n\n0111000\n+26 0 *\nVe\n1e-07\n10 0 30\n0 0\n\n0101101\n*\nVe\n1e-07\n10 0 0\n0 0\n\n0101101\n*\nEd\n 1e-07 1 1 0\n1 5 0 0 30\n2 9 6 0 0 30\n2 10 2 0 0 30\n0\n\n0101000\n-24 0 +23 0 *\nVe\n1e-07\n10 20 30\n0 0\n\n0101101\n*\nEd\n 1e-07 1 1 0\n1 6 0 0 20\n2 11 6 0 0 20\n2 12 3 0 0 20\n0\n\n0101000\n-21 0 +24 0 *\nVe\n1e-07\n10 20 0\n0 0\n\n0101101\n*\nEd\n 1e-07 1 1 0\n1 7 0 0 30\n2 13 6 0 0 30\n2 14 4 0 0 30\n0\n\n0101000\n-21 0 +19 0 *\nEd\n 1e-07 1 1 0\n1 8 0 0 20\n2 15 6 0 0 20\n2 16 5 0 0 20\n0\n\n0101000\n-19 0 +23 0 *\nWi\n\n0101000\n-22 0 -20 0 +18 0 +17 0 *\nFa\n0 1e-07 6 0\n\n0111000\n+16 0 *\nEd\n 1e-07 1 1 0\n1 9 0 0 10\n2 17 2 0 0 10\n2 18 5 0 0 10\n0\n\n0101000\n-23 0 +33 0 *\nEd\n 1e-07 1 1 0\n1 10 0 0 10\n2 19 2 0 0 10\n2 20 3 0 0 10\n0\n\n0101000\n-24 0 +34 0 *\nWi\n\n0101000\n-14 0 -22 0 +13 0 +32 0 *\nFa\n0 1e-07 2 0\n\n0111000\n+12 0 *\nEd\n 1e-07 1 1 0\n1 11 0 0 10\n2 21 4 0 0 10\n2 22 5 0 0 10\n0\n\n0101000\n-19 0 +29 0 *\nEd\n 1e-07 1 1 0\n1 12 0 0 10\n2 23 4 0 0 10\n2 24 3 0 0 10\n0\n\n0101000\n-21 0 +31 0 *\nWi\n\n0101000\n-10 0 -18 0 +9 0 +28 0 *\nFa\n0 1e-07 4 0\n\n0111000\n+8 0 *\nWi\n\n0101000\n-27 0 -10 0 +17 0 +14 0 *\nFa\n0 1e-07 5 0\n\n0111000\n+6 0 *\nWi\n\n0101000\n-30 0 -9 0 +20 0 +13 0 *\nFa\n0 1e-07 3 0\n\n0111000\n+4 0 *\nSh\n\n0101100\n-25 0 +15 0 -11 0 +7 0 -5 0 +3 0 *\nSo\n\n1100000\n+2 0 *\n\n' p5 I0 tp6 b.
