Beam Connection in Revit, Beam on Circle and Surface doesn't show up in Revit



for a student project in my university i build an hyperboloid out of lines. Now when i put beams on the lines they don’t connect themselve correctly at the bottom. Also I can’t put beams on my circles because the “curve is not bound”. Also the surface I put on doesn’t show up in Revit. Here is the file:dynamo_3

Can you help me with that?
