Rectangular Components - Taper

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

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

   

   You are required to input the following dimensions:

   • Duct width AA

   • Duct depth AB

   • Duct width LA

   • Duct depth LB

   • Length

   • A Offset

   • B Offset

   • Arrive Extension

   • Leave Extension

     To visualize how the dimensions equate to the actual piece of HVAC, select Picture to display a detailed drawing for OW-Taper.

     Note: The fields will be pre-populated with default dimensions. These dimensions are governed by the details defined in the HVAC Catalog. The Arrive and Leave Extension default is auto but can be changed to a required dimension.

2. Select Transpose width/depth to exchange Duct width AA dimension with Duct depth AB dimension or to exchange Duct width LA dimension with Duct depth LB dimension.

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

4. After selecting the type of joint to use for the Arrjoint and Leajoint the user must enter the Aoff Direction.

5. In the Aoff Direction enter the direction for the A Offset or B Offset relative to the Point of Origin.

   Valid directions are X (East), Y (North), Z (Up), -X (negative East), -Y (negative North) or -Z (Negative Up).

6. 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.

7. Select Defaults to reset all the fields back to when the Taper window was opened.

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

9. Select OK to create the Taper component and close the Taper Window. You are returned to the HVAC Window.

10. Select Cancel to discard all field changes and close the Taper window
