Oval ‘A’ to Oval ‘B’

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

Select Transformations in the Categories drop-down list and then Oval ‘A’ to Oval ‘B’ in the Available Type drop-down list to display the Oval A to Oval B 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

• Male Collar A

• Male Collar L

To visualize how the dimensions equate to the actual piece of HVAC, click Picture to display a detailed drawing for Oval A to Oval B.

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

Click Transpose Width/Depth to exchange Duct Width AA dimension with Duct Depth AB dimension or exchange Duct Width LA dimension with Duct Depth LB dimension.

Specify a type of joint to use for the Arrive Joint and Leave Joint. Refer to Create/Modify HVAC Component for a detailed description.

After selecting the type of joint to use for the Arrive Joint and Leave Joint you must enter the A Offset Direction.

In A Offset Direction enter the direction for the A Offset relative to the Point of Origin. Valid directions are E (East), N (North), U (Up), -E (negative East), -N (negative North) or -U (Negative Up).Using the Flip Arrive/Leave drop-down list, you can choose whether to flip the direction of arrive and leave of the of the piece of HVAC, 180° relative to the point of origin.

In the Position list, select Connect or Unchanged:

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

• Click 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.

Click Defaults to reset all the fields back to when the Oval A to Oval B window was opened.

Click Fit to orientate the Oval A to Oval B to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.

Click OK to create the Oval A to Oval B component and close the Oval A to Oval B Window. You will be returned to the HVAC Window

Click Cancel to discard all field changes and close the Oval A to Oval B window.
