Before saving the family, execute a rigorous test protocol:
Cause: You tried to set TubeLength to 0 or a negative number.
Fix: In Family Types, set a minimum value. Go to Parameters > Edit Formula. Type: TubeLength = if(TubeLength < 300 mm, 300 mm, TubeLength)
Go to Family Category and Parameters. Check "Airflow" or "Fluid Flow" . shell and tube heat exchanger revit family work
A heat exchanger is a node in a system. Without connectors, it is a paperweight.
To make your shell and tube heat exchanger Revit family work useful for the project, you must use Shared Parameters. Before saving the family, execute a rigorous test
Create a Shared Parameter file (.txt) with the following fields:
Load these into your family via Family Types > New Parameter > Shared Parameter. Now your heat exchanger shows up correctly in MEP schedules. Load these into your family via Family Types
Shell and Tube heat exchangers present a unique challenge in BIM environments. Unlike compact plate heat exchangers, shell and tube units are linear, heavy, and often require specific maintenance clearances. Creating a Revit family for this equipment requires balancing mechanical detail with file performance, ensuring the model serves both coordination and facilities management needs.
