To Connect a Duct Run to Equipment

When you start or end a run at a piece of equipment (MvPart), the start point or endpoint snaps to the nearest connection point on the MvPart. Simple MvParts, such as terminals, fans, and humidifiers, contain only one connection point. However, many of the more complex types of MvParts, such as tanks and pumps, contain multiple connection points. Some MvParts even have connection points that belong to different domains, such as a furnace that has both duct and pipe connection points.

Note: This procedure assumes that you have placed equipment in your drawing. For more information, see To Connect a Duct Run to Equipment.

To connect a duct run to equipment

1. In the HVAC workspace, choose an action below:
   • Click Home tab Build panel Duct drop-down Duct .
   • Open the Duct tool palette, and select a duct tool.

   If you select a duct tool with a specific, predefined system (for example, the Supply - Low Pressure tool), the duct that you draw inherits the system’s properties, such as its design parameters, display properties, and rise and drop style.

2. With AutoCAD MEP 2023 toolset snaps enabled, select a starting point for the segment at the connector of an MvPart, and continue selecting points to draft the run as necessary.

   The default run direction of the duct is dependent on the connector assigned to the MvPart. Typically, the run direction is perpendicular to the connector face of the MvPart.

   The type of connector assigned to the MvPart and the connector rules specified in the drawing determine the type of segment that can be connected to the MvPart.

3. Press Enter to end the command.
