HVAC Transitions Gallery

Used to place HVAC transition components.

Accessed from the HVAC ribbon:

The following gallery displays which can be left floating or docked to the drawing area.

The following table shows the component options in the gallery along with the key in syntax. Selecting a tool from one of the placement galleries activates the Place Component dialog. The generic placement settings, along with the unique set of dimensional and data properties provide the core workflow used to accurately position equipment components in the model.

Component	<Component Class> in Placement Key In syntax (Mechaddin Place <Component Class> dsc=HVAC)
Transition	HVAC_RECTANGULAR_TRANSITION
Rectangular to Round	HVAC_RECTANGULAR_TO_ROUND_TRANSITION
Rectangular to Oval	HVAC_RECTANGULAR_TO_OVAL_TRANSITION
Round Transition	HVAC_ROUND_TRANSITION
Double to Single Round Transition	HVAC_DOUBLEWALL_TO_SINGLEWALL_TRANSITION

Component Placement

Select an option from the Transitions taskbar/toolbox to display the Place Component. This dialog is common to all HVAC components and allows you define a component's physical parameters as well as general properties before placement. The dialog remains ope dialogn throughout the placement process.

In the Place Component dialog's Settings tab, select a placement point to determine which port serves as the placement point for the component. The options in the Placement Point list will vary depending on the component being placed. (Available Placement Points for a Transition are Main_Port and Run Port.)

The HVAC Port Settings tab of the Place Component dialog allows you to define the End Preparations for the ports on the component to be placed. An example is shown below:

End Prep	Defines which port to apply the EndPrep Type, Size and Length values to. You are able to define different values for each port if desired.
EndPrep Type	HVAC_Flange_End, HVAC_MALE_END, HVAC_Female_End, HVAC_Plain_End
EndPrep Size	Enter a size for the EndPrep Type. Note: This is disabled if HVAC_PLAIN_END is selected.
Endprep Length	Enter length for the selected EndPrep Type.

The Design Conditions tab provides fields to define the physical parameters of the component. The field options will vary depending on the type of component being placed.

While enter/changing values in the fields, the component is dynamically updated in the drawing so you can see the changes before placing the component.

An example of the design conditions field is displayed below:

Note: If placing a predefined component from the spec, most of the dimension parameter fields in this tab will be read only.

Once the component parameter and property values are defined you are prompted to select a placement location for the component. Pick a location and click a data point. If the component requires a direction pick, use the mouse to rotate the component into the correct position then click a data point. Right-click to complete the process.
