1. Select Circular in the Categories drop-down list and then Radiused Threeway in the Available Type drop-down list to display the Radiused Threeway window:

   

   The user is required to input the following dimensions:

   • Duct Diameter

   • Second Diameter

   • Angle

   • Second Angle

   • Inside Radius

   • Second Radius

   • A offset

   • B offset

   • Arrive Extension

   • Leave Extension

   • Second Aext

   • Second Lext

   • Male Collar (A)

   • Male Collar (L)

   • Male Collar (B)

2. To visualize how the dimensions equate to the actual piece of HVAC, click Picture to display a detailed drawing for Circular Components Catalog Element - Radius Threeway.

   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 by the user to a required dimension.

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

   • 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.

8. Click Defaults to reset all the fields back to when the Radiused Threeway window was opened.

9. Click Fit to orientate the Radiused Threeway to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.

10. Click OK to create the Radiused Threeway component and close the Radiused Threeway Window.

    The user will be returned to the HVAC Window.
