The task of creating an HVAC Component is initiated from the HVAC Window.

  1. Select Rectangular in the Categories dropdown list and then Material Connection in the Available Type dropdown list to display the Material Connection window:

    You are required to input the following dimensions:

    • Duct width AA

    • Duct depth AB

    • Overall length

    • Mat’l Thickness

    • Arrive Slipover

    • Leave Slipover

  2. To visualize how the dimensions equate to the actual piece of HVAC, select Picture to display a detailed drawing for Rectangular Components Catalog Element - Material Connection.

    Note: The fields will be pre-populated with default dimension. These dimension are governed by the details defined in the HVAC Catalog.

  3. Select Transpose width/depth to exchange Duct Width AA dimension with Duct depth AB dimension.

  4. Specify a type of joint to use for the Arrjoint (Arrive Joint) and Leajoint (Leave Joint). Use this type of joint for the inlet side of the component. For a detailed description, see Create / Modify HVAC Components.

  5. After selecting the type of joint to use for the Arrjoint and Leajoint, enter the Width Direction.

  6. In the Width Direction specify the axis to be used. Valid axes are E (East), N (North), U (Up), -E (negative East), -N (negative North) or -U (Negative Up).X, Y, Z, -X, -Y or -Z.

  7. In the Connect list, select Connect or Unchanged:

    • Select Connect (default when Create is selected) - connects the piece of HVAC to the previous one.

    • Select Unchanged (default when Modify is selected) - positions the component at the co-ordinates 0.00.

    Note: Unchanged is usually used, when Modify is selected, it does not connect the component but positions it at 0.00, in effect in a floating position.

  8. Select Defaults to reset all the fields back to when the Material Connection window was opened.

  9. Select Fit to orientate the Material Connection to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.

  10. Select OK to create the Material Connection component and close the Material Connection Window. You will be returned to the HVAC Window.

  11. Select Cancel to discard all field changes and close the Material Connection window.
