All of the tasks you would carry out that are associated with the creation or modification of HVAC are initiated from a central HVAC window which acts as a task hub.
Depending on selections made in the HVAC window you will be presented with further windows prompting for user input. After inputting information in these windows you will always be returned to the HVAC window allowing the workflow to continue.

To open the HVAC window, select Create > HVAC from the main menu bar to display the HVAC window.

Categories
HVAC tasks are initiated by first selecting an entry from the Categories dropdown list. These categories are standard types of HVAC provided by the application with the exception of User Defined Fittings or Create Assemblies out of Components.

Depending on the entry selected in the Categories dropdown list the Available Types dropdown list will present you with a different set of options.
Available Types
After selecting a category of HVAC, you can choose a specific type of HVAC element from the Available Types list.
When a selection is made from the Available Types dropdown list a separate window will be displayed allowing the user to input specific criteria based on what type of HVAC component is being created. For example the user could be prompted to enter dimensions for a straight piece of HVAC.
Note: The windows that are presented are as a result of selecting an Available Type. These are described more in detail in the following sections of this guide.

The user will not be able to select certain Available Types if the correct database hierarchy has not been configured beforehand. For example certain HVAC elements must reside below other elements in the database hierarchy (an overview of the database hierarchy is described in Hierarchy).
The different combinations of selection that can be made from the Categories and Available Types dropdown are listed in the Menu Map.
If a particular HVAC element cannot be created at the current position in the database hierarchy you will receive an error message summarizing the problem, for example in the following window an error explains that the element the user is attempting to create must reside below an HVAC Branch or HVAC Component element:

After populating the windows that are opened by selecting the Available Type, you will always be returned to the HVAC Window.
