: Start with a Metric Generic Model or Mechanical Equipment family template. Establish Framework :
Use formulas. For example, constrain TotalLength = TubeLength + FrontHeadLength + RearHeadLength . This prevents geometric errors when users modify values in the project. shell and tube heat exchanger revit family work
Built-in "Pipe Connectors" with predefined flow directions, system classifications (Hydronic Supply/Return), and pressure drop parameters. : Start with a Metric Generic Model or
