I’m trying to create pipe from polycurve it has showing an error (Warning: PipeNetwork.AddPipeByCurve operation failed. Object reference not set to an instance of an object.), anyone know how to rectify this error? [Screenshot (2)] [Screenshot (4)] pipe.dyn (26.4 KB)

hi check [image] Create Pipes from polylines Civil3D I think it has to be a Line or Arc, not a PolyCurve?

Even I tried with line it has same error

Are you try with arc If yes with error , attached example drawing

Hi, you must create the geometry using linebystartpointEndPoint. you can’t use object geometry as input in pipenetwork.AddPipeByCurve. [Forum]
