If this feature were to be implemented it would also be nice to have a fire damper schedule. It might include tag, size, type, etc... This is often required on medical projects.

We do have the ability to insert a basic fire / smoke damper using the DM HVAC->Fittings->Fire / Smoke Damper command. It includes the pressure drop through the damper.

It is limited to two types and not at all customizable. If we implemented this feature, it would be to expand the dampers to be able to include custom graphics.

We need the pressure drop of these devices included in the pressure calcs too.
