Thomas, I guess the way to do "cast" in pythonOCC is as follows:
unionop = BRepAlgoAPI_Fuse(TopoDS().solid(aShape), box) [as seen in the routine ShapeToTopology that you have written somewhere] But that doesn't help either. I get. RuntimeError: Standard_TypeMismatch TopoDS::Solid Did you mean any other way of casting to TopoDS_SOLID? -- Jayesh On Thu, Dec 8, 2011 at 4:30 PM, Thomas Paviot <tpav...@gmail.com> wrote: > Did you try to cast the compound to a TopoDS-Solid? > > Thomas > - sent from my Android phone > > Le 8 déc. 2011, 10:07 AM, "Jayesh Salvi" <jayeshsa...@gmail.com> a écrit : > > > After more investigation of why NotDone is thrown, I have found some info. > > The Fuse operation has ErrorStatus() function on it.
