Check Duct Systems

This tool examines the mechanical systems that you create in a project to verify that each system is assigned to a user-defined system, and properly connected.

Checking Duct Systems

To verify the connections for duct systems in the model, click Analyze tabCheck Systems panel Check Duct Systems.

Revit displays graphical warning markers and web lines for invalid duct systems in the current view. Warnings display when the following conditions are found:

• The system is not well connected.

  A system is considered not well connected when elements in the system are not connected into a single physical network. For example, a system with one or more air terminals not connected in a single network of duct is considered not well connected.

• There is a flow/demand configuration mismatch.
• There is a flow direction mismatch.
