Hello Balint,
Try this code...
def cut_face (self):
HubImporter = STEPImporter("/home/arch/hub1.stp")
HubImporter.read_file()
shapeList = HubImporter.get_shapes()
hubSurface = shapeList[0]
CutImporter = STEPImporter("/home/arch/cuttingProfile.stp")
CutImporter.read_file()
shapeList = CutImporter.get_shapes()
cuttingProfile = shapeList[0]
splitter = GEOMAlgo_Splitter();
splitter.AddShape(hubSurface);
splitter.AddTool(cuttingProfile);
splitter.Perform();
splitter_shape = splitter.Shape();
topo = Topology.Topo( splitter_shape )
topo.number_of_faces()
mod_shape = topo.faces().next()
self._display.DisplayShape( mod_shape )
good luck!
