Hi Andy, thanks for your support. The function self.newSlice.GetDataInformation().GetNumberOfPoints() returns zero points then the functions fails. But it is kind of wired because I use always the same origin and normal vector and sometimes it is successful. Ok, now I know the problem and I try to fix it.
