A BIM model is a database, not just a drawing. Ensure your family includes: Fouling Factor Pressure Drop (Shell & Tube sides)
In Floor Plan view, use symbolic lines to represent the heat exchanger according to industry standards (typically a rectangle with a diagonal or "S" curve). 5. Data and Shared Parameters
Use a simple box or cylinder representing the "clearance zone" required to pull the tube bundle for maintenance. shell and tube heat exchanger revit family work
Link the connector's "Pipe Diameter" to a family parameter. This ensures that when you change the unit size, the pipe pipes automatically resize to match. 4. Visibility Graphics (LOD Management)
Perhaps the most overlooked part of the workflow is the . Use a transparent "Void" or a dedicated sub-category called "Maintenance Zone." This allows you to run Clash Detection in Navisworks or Revit to ensure no pipes or conduits are blocked where the tubes need to be extracted for cleaning. Summary Checklist for Your Workflow A BIM model is a database, not just a drawing
Before you place your first reference plane, decide on the family's purpose.
for the shell length and nozzle offsets. Data and Shared Parameters Use a simple box
By following this workflow, your shell and tube heat exchanger families will be more than just 3D blocks—they will be intelligent assets that drive the accuracy of your entire MEP system.
Use a simple Extrusion or Revolve . Avoid modelling the internal tube bundle; it adds "polygons" that Revit has to calculate without providing any BIM value. The Heads: Use Sweeps for the rounded end-caps.
