When creating an MEP fabrication model, you can add, remove, or rotate integral damper blades using in-canvas controls that are specific to dampers.
This video demonstrates the following:
In a Revit model, you can quickly add dampers to MEP fabrication ductwork parts. For example, you can add an integral damper blade to a round or rectangular tap.
To add a damper, select the part, then click the Add Damper control. Click the Change Damper Type control to select the type of damper from the drop-down list. The damper is added to the part.
You can also change the damper type once it is added. In this example, we'll change a manual damper to an electric damper.
Select the part that includes the damper, then click the name of the damper type, in this case ADSK Manual. In the Damper Type drop-down list, select the new damper type, in this case ADSK Electric Actuator.
To change the location of the damper relative to the connector, use the Rotate controls. In this example, the damper handle is located on the right side of the connector.
To change this location, rotate it by selecting the tap, then clicking the Rotate Damper control several times. This rotates the damper shaft in a counterclockwise direction, around the connector.
These controls rotate in 90-degree increments for rectangular parts, and 45-degree increments for round parts.
To remove a damper, simply select the part that includes the damper, then click the Remove Damper control. The damper is removed from the part.
This feature significantly reduces the time it takes to add and edit integral dampers blades on Revit MEP fabrication ductwork parts.
