Diffuser Connections
This section describes the commands used to connect ducts to diffusers.
Size diffuser runout to match diffuser neck size: Sets whether the runout to a diffuser is sized based upon the airflow in the system or the diffuser neck size.
Default flex length: Sets the maximum length of flex duct used to make a diffuser connection.
Damper far from diffuser: Sets where balancing dampers are placed along ductwork.
Ceiling Connection: Fitting graphics: Sets how ceiling diffuser connections are displayed in 2D.
Connection Graphics: Sets how flex duct and hard duct diffuser connections are displayed in 2D.
📄️ Change Connection Type
The Change Connection Type command is used to change the settings used when a diffuser connection is made. These settings only affect newly inserted diffuser connections. Diffuser connections made before the changes must be modified manually using the Query Duct or Edit Multiple Ducts commands.
📄️ Perpendicular Connection
The Perpendicular Connection command is used to make a perpendicular connection between a duct and one or more diffusers.
📄️ Single 90 Connection
The Single 90 Connection command inserts a diffuser connection that extends perpendicular to the selected duct, then turns 45 degrees to connect to the selected diffuser.
📄️ Single 45 Connection
The Single 45 Connection command inserts a diffuser connection that extends at a 45-degree angle to the selected duct, then turns 45 degrees to connect to the selected diffuser.
📄️ End Connection
The End Connection command inserts a diffuser connection that extends from the end of a duct directly to a diffuser. The connection is inserted as a straight line. No additional turns or adjustments to the duct path are inserted.
📄️ Bottom Connection
The Bottom Connection command inserts a diffuser connection between a duct and a diffuser directly below it.
📄️ Transparent Connection
The Transparent Connection command inserts a connection between a duct and a diffuser for which the graphics will not be drawn. Airflow will be transferred from the diffuser to the duct.
📄️ Vertical Transparent Connection
The Vertical Transparent Connection command inserts a connection between a duct and a diffuser for which the graphics will not be drawn. A vertical duct will be displayed at the diffuser. Airflow will be transferred from the diffuser to the duct.
📄️ Disconnect Diffuser
The Disconnect Diffuser command is used to remove a connection between a duct and a diffuser on the drawing. A duct that is connected to a diffuser has its end point fixed to the diffuser insertion location. The duct cannot be moved away from the diffuser, and moving the diffuser moves the duct as well. This command will disassociate the diffuser and duct so they can be moved independently.
