Ventilation Add Volume Control Dampers To All Branches

Ventilation Commissioning writes to model Public API · not yet exposed

Coming soon

Before you run this

One mechanical duct system selected (or one duct in the system). VCD family loaded; project standard or active preset has a damper-to-duct-size mapping.

After it runs

One VCD family instance per branch take-off, sized to the branch duct, inserted with the airflow direction set; system network preserved.

When to use this

Don't use this when

Branches already balanced with iris dampers, fire/smoke damper locations (those are placed by the fire damper command), or kitchen extract systems where commissioning is set elsewhere.

Decision flow

1. Walk the ducts in the system and find every branch tee.
2. For each branch, pick the VCD family + size that matches the branch duct.
3. Insert the damper a configurable distance downstream of the tee in one Transaction.
4. Set the airflow direction parameter to match the branch flow.
5. Report how many dampers were added and any branches skipped (e.g. duct too short).

What you'll see in the chat

on start
I'll add VCDs to every branch on this system — walking the network now.
thinking
Finding branch take-offs from the main and matching damper sizes.
Inserting dampers downstream of each tee with the right airflow direction.
on success
Done — {n_placed} VCDs added across {n_branches} branches. {n_skipped} branches skipped: {skip_reasons}.
on failure
Couldn't add the dampers: {error}.
