Place Air Terminals

This tool lets you place air terminals in a project. When devices such as air terminals are placed in a view, information associated with them is used in calculating loads for the spaces (rooms) in a duct system. The rooms keep a running total of the amount of supply, return, and exhaust air supplied or removed from a room, which allows you to select the correct air terminal sizes.

Specify component elevation

1. Open a view containing the duct system where you want to add an air terminal.
2. Click Systems tabHVAC panel Air Terminal, and in the Type Selector, select an air terminal type.
3. On the ribbon, specify mode options:
   • Load Family. Loads component family.
   • Model in-place. Lets you create a new family of a specified component that will be available only in this project.
4. On the ribbon, verify that Tag on Placement is selected to automatically add a tag. Then specify the following tagging options on the Options Bar:

   If you want to...	then...
   change the orientation of the tag	select Horizontal or Vertical.
   load additional tags	click Tags.
   include a leader line between the tag and the terminal	select Leader.
   change the default length of the leader	enter a value in the text box to the right of the Leader check box.

5. To place an air terminal directly on the face of duct, click Modify | Place Air Terminal tabLayout panel Air Terminal on Duct.

   You can place a new air terminal on a duct, or drag an existing air terminal and place it on a duct.

   Notes:

   • Only unhosted air terminals are supported.
   • Move the cursor inside the duct to snap the air terminal to the face of the duct.
   • When placing an air terminal on the side face of a duct, the insertion point is the family insertion point.
   • When placing an air terminal on the end of a duct, the insertion point is controlled by the connector.
6. On the Options Bar, for non-hosted air terminal options, specify
   • Rotate after placement which rotates a component after placing it in the view.
     Tip: You can also press the Spacebar when placing a component to rotate it in 90 degree steps.

   Some air terminals are hosted components that must be placed on a work plane.

7. If you selected a hosted air terminal, click Place on Work Plane to specify a host component.
   Tip: When placing an air terminal on a work plane, it may be necessary to Pick a Plane in the Workplace dialog, or select a Placement Plane on the Options Bar when placing the component.
8. Move the cursor to where you want to place the air terminal and click.
9. Click Modify.
10. If you are placing an un-hosted component, select the air terminal, and in the Properties palette, enter an Offset value to specify the elevation.
Note:
In some cases, air terminals may be placed so that the location of the connector is not inside a space. The room calculation point is used as a search point to determine what space the air terminal is in. You can edit the family for the air terminal to enable the Room Calculation Point, and then move the location of the calculation point so that it is located inside the space. In the Family Editor, in the Properties palette, enable Room Calculation Point. Edit the location of the Room Calculation Point so that it is located inside the space.


Since the room calculation point specifies which space the air terminal is in, it is also reflected in schedules. For example, if you include a column in the schedule with Space data, such as name and number, the space dictated by the room calculation point will be used.
