A tree of the model’s structure can be displayed by choosing Model > Model Tree as shown.

This opens a tree dialog that shows all of the model’s components organized by the component’s class.

The Model Tree behaves like any standard tree in that you can expand the hierarchy by clicking on the ‘+’ that is displayed to the left of entries.

Similarly, you can collapse the hierarchy by clicking on the ‘-’.

The number in parenthesis to the right of the class name indicates the number of instances of that class in the model.

In the example shown there is one (1) Exterior Pipeway, named “main” in model and the “main” pipeway has only one section.

Double clicking on nodes in the tree that do not have an instance count to the right of the class name opens the appropriate editor for that class.

If a node is selected and the right mouse button is pressed, displays a pop-up menu. The pop-up menu contains the same entries as the Edit menu bar selection.

The pop-up menu as shown below allows you to, Edit, Rename, Delete, Find, Zoom To, Highlight, UnHighlight Component, or UnHighlight All components. You can also turn on the Auto-Zoom and/or the Auto-Highlight options in the pop-up menu.

In all cases, you are warned if the chosen action is not appropriate for the selected component.

Setting	Description
Edit	As discussed above, opens the appropriate editor for the class of the selected node.
Rename	Lets you rename the selected component.
Delete	Lets you delete the selected component.
Find	Opens a dialog that allows you to enter a name or a name with wild cards to be used as a search string. When the OK button is clicked, PlantWise searches for all components that match the search string. For example, if the model contains numerous items that have a naming convention such that the prefix 80-E is used for related items, you could enter 80-E-* in the dialog’s input field. When you click the OK button displays a dialog that lists all the components that match the search string. Selecting one of the components and clicking the Select button it that dialog causes the Model Tree to select the component’s node in the tree as shown below.
Zoom To	Causes CAD to prompt you to select a view. When a view is selected, the currently selected component fills that view. You can then select other views in CAD and they also be zoomed so the component fills the view. Note: Some times the Zoom To, or the Auto Zoom, affects the clipping planes. If the component does not appear in the view, turning off the front and/or back clipping plane should make the component visible.
Highlight	Highlights the currently selected component.
UnHighlight Component	Unhighlights the currently selected component.
UnHighlight All	Unhighlights all components, regardless of which component/node is currently selected.
Auto-Zoom	When turned on, causes CAD to zoom the last view to receive a data point such that the selected component fills the view. After the initial zoom, you can select additional views to zoom to the component. Note: The view that appears to have focus may not be the last view to receive a data point. If you are unsure, simply click in the view that you want the Auto-Zoom to change.
Auto-Highlight	When turned on, causes items to be highlighted as they are selected. Note: The Model Tree dialog is NOT dynamically updated. If changes are made to the model that would affect the contents of the Model Tree, you must refresh the dialog by clicking the Update button in the lower left corner of the dialog.
