Notilus Piping is a plugin that allows piping and 3D modeling in Rhino. In pipeline modeling, TEs and reductions are automatically added to the model by drawing pipes of the desired diameter and standard. Nautilus piping allows changing the pipes characteristics dynamically. Bill of materials can be added directly into Rhino or exported in CSV format. Tongues in curtain transitions are created automatically. Valves and fittings of the desired diameter can be added from the Valve and Fittings library.
