Define the appropriate parameter type, set the units (millimeters, inches, etc.), and give the parameter a clear, descriptive name. Using clear naming conventions, such as "Shell Diameter" or "Tube Length," ensures that other team members can quickly understand how the family is structured.
Flow_Rate (Fluid Flow - mapped to the connector properties). Identity Data
Do not use generic templates, as they lack the built-in parameters required for HVAC and piping systems. Define Family Categories and Parameters shell and tube heat exchanger revit family work
This section outlines a structured workflow for creating a basic parametric shell and tube heat exchanger family, based on standard Revit practices.
Go to Family Category and Parameters . Check or "Fluid Flow" . Define the appropriate parameter type, set the units
: Draw pipes to all four nozzles. Verify that the pipe sizes resize automatically if the family nozzle diameter parameters are updated.
You dimensioned the nozzle to a static plane instead of a reference plane driven by ShellDiameter . Fix: Lock the nozzle’s origin intersection to the intersection of the shell’s centerline and the outer edge reference plane. Identity Data Do not use generic templates, as

Add reference planes to the left and right of the center to define the total length of the shell.
