To Add Connectors to a Parametric Air Terminal MvPart

Use this procedure to add connectors to a parametric air terminal MvPart. Typically, air terminals have a single connector on the top face of the diffuser to provide a connection point for the flex duct.

  1. To create the connector geometry for flex duct, in the part browser, right-click Lip Offset and click Add Profile Circular.
  2. In the modeling area, using object snaps, select the center point of the top face of the diffuser, enter 3" (76 mm) for Radius, and press Enter

    A circular profile for the flex duct connector is created and is added to Lip Offset in the part browser.

    Attention: The position of the first connector placed in the model defines the axis orientation of the part upon insertion. For example, if you place the first connector on a part with a perpendicular vector into the part, the direction of the vector defines the positive x-axis orientation when inserted in a drawing.
  3. In the part browser, right-click Modifiers, click Add Extrusion, and select the circular profile.

    The Extrusion Modifier dialog box is displayed.

  4. Under Termination, select Blind for Type and enter 4" (102 mm) for distance. Click OK.

    A cylinder is created to represent the flex duct connector, and a second extrusion modifier is added to Modifiers in the part browser.

  5. To add a connector, in the part browser, right-click Connections and click Add Connection.

    You are prompted to select the connector location. As you move the cursor around in the modeling area, it snaps to 4 possible locations for a connector—the top and bottom faces of the diffuser, and the top and bottom of the flex duct connector.

  6. Select the center point of the top of the flex duct connector and press Enter to accept the default value for the connector number.
    Note: The default connector numbers are in ascending numeric order, according to the order in which the connectors are added to the model. For example, the first connector is 1, the second connector is 2, and so on. You can model connections for MvParts in any order.
  7. Pick a location above and to the right of the model to place the dimension for the diameter of the flex duct connector.

    A diameter dimension (D1) is added to the model for the diameter of the flex duct connector and to Model Parameters in the part browser, and a connector is added to Connections.

  8. To define the domain and type of connection for the connector, in the part browser, expand Connections, right-click Connector 1, and click Edit.

    The Connector Properties dialog box is displayed.

  9. Select Domain from the list.

    Connector domains are dependent on the specified shape of the modifier to which the connector is attached.

  10. Select Banded for Type from the list.

    Connector types are dependent on the connector domain.

    Connection Types Selection dialog box

    Note: Connectors are assigned an undefined type by default. An undefined connection type creates a valid connection between all types of connectors when inserted in a drawing.
  11. Click OK.
