Design the Duct Systems

Connect compatible air terminals and air handling equipment to provide the heating and cooling required for the project.

Add air terminals and air handling equipment.   Use the Heading and Cooling Loads report to determine the capacity for air terminals and equipment. Place air terminals and air handling equipment in the plan.
Create the duct systems.   Assign grills, air terminals and air handling equipment to supply, return, and exhaust systems.
Lay out ductwork.   Use Generate Layout tools to create and route ductwork connecting your air terminals and air handlers.
Modify duct routing.   Change the routing and manually adjust ductwork to avoid obstructions.
Align ductwork.   If necessary, justify sections of ductwork.
Calculate duct sizes.   Revit sizing tools let you automatically specify duct sizes that provide the correct flow throughout your systems.
Create groups and copy them to other areas in the project. (optional)   You can create groups of components to replicate similar systems in other spaces or on other levels.
Check the systems.   Check the connectivity throughout your systems.
Inspect the systems.   Use the system inspector to verify flows.
