Creating Pipe with polyline in Civil3D

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?


pipe.dyn (26.4 KB)

hi

Even I tried with line it has same error

If yes with error , attached example drawing

I haven’t tried with Arc

Q

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