Diffusers Gallery

Used to place HVAC Diffuser 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)
Rectangular Supply Diffuser	RECTANGULAR_SUPPLY_DIFFUSER
Round Supply Diffuser	ROUND_SUPPLY_DIFFUSER
Oval Supply Diffuser	OVAL_SUPPLY_DIFFUSER
Round Diffuser	ROUND_DIFFUSER

Component Placement

Select an option from the Diffusers gallery to display the Place Component dialog. 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 open 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. When placing a Diffuser the Main_Port is the only Placement Point available.

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_PLAN_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:

Once the component parameter and property values are defined you are prompted to select a placement location along the duct segment. Use the mouse to slide the access door along the duct segment to the correct 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.
