Ventilation Create Extract System From Grilles
Coming soon
Before you run this
One or more extract grilles selected. A Mechanical Equipment family for the AHU / fan unit exists in the model or the project standard provides one.
After it runs
A new Mechanical Duct System is created with the selected grilles assigned to it; system name + abbreviation set; selection moved to the new system.
When to use this
- You've placed your extract grilles, you want them grouped into a single Revit system so you can run sizing or connect them to an AHU without picking each grille manually.
Don't use this when
Supply systems (run the matching supply-side command), VAV / mixed systems, or grilles that should sit on more than one extract system.
Decision flow
1. Read the selected grilles and verify each has an extract connector available. 2. Resolve the system type from the project standard (or the active preset). 3. Create a new MechanicalSystem in one Transaction; assign every grille to it. 4. Set the system name + abbreviation from the room or zone. 5. Report the new system id and how many grilles joined it.
What you'll see in the chat
