Showing and Hiding Model Parts with the Model Tree

In this section, you'll learn how the Model Tree enables you to work with parts or views of the model.

The Model Tree opens in the navigation pane, to the left of the document pane in the work area. You use the Model Tree to show, hide, or isolate parts in the 3D model, to create views to which you can return later, and to display any metadata that was included for the 3D model in the authoring program. (Metadata could include object properties such as mass, material, and center of gravity, for example.)

  1. To open the Model Tree, do one of the following:
    • Click the Model Tree button (see Figure 16) in the navigation pane to the left of the document pane.
    • Click the Toggle Model Tree button on the 3D toolbar.
    • Right-click (Windows) or Control-click (Mac OS) the 3D model and choose Show Model Tree from the context menu.

    The Model Tree has three panes (see Figure 17):

    • The Structure pane at the top of the Model Tree shows the tree structure of the 3D object. You expand the model's structure by clicking the plus sign or arrow next to any component. Selecting any part in the Structure pane highlights that part in the 3D model. Selecting any part in the model automatically expands the structure and highlights that part's label in the Structure pane. A blue checkmark indicates that the part is visible in the 3D model.

      If product manufacturing information (PMI) has been added to the model, it will appear as a group of items on the same hierarchical level as its related object or assembly.

    • The Views pane in the middle of the Model Tree lists the defined views of the model. You can define new views and edit existing views. For example, after you isolate and rotate a part, you can save that particular view. Any views created with the Camera Properties tool are also listed in this pane.
    • The Object Data pane at the bottom of the Model Tree displays properties or any available metadata for the object or part selected in the model. You cannot edit this information for 3D objects in Acrobat.

    Now you'll use the Model Tree to hide the outer cover of the water bottle to show the filter.

  2. In the document window, click the 3D model to open the 3D toolbar automatically.
  3. In the upper pane of the Model Tree (the Structure pane), click the plus sign or triangle next to Aquo_Bottle to expand the list of parts (see Figure 18).
  4. If necessary, widen the navigation pane by dragging its right border to the right. Enlarge the Structure pane by dragging the lower border down.

    Notice that all the parts in the Structure pane are selected. Selected parts are visible in the 3D model in the work area.

  5. Deselect Ring to remove the checkmark. (You may need to scroll down in the Structure pane to see the Ring listing.) This action hides the ring around the neck of the water bottle (see Figure 19).
  6. Select Ring again to restore the checkmark and display the ring.

Selecting Parts

You can easily identify a part in the 3D model by selecting the part in the Structure pane.

  1. In the Structure pane, expand the structure, and select the label Water_Bottle_Lid_Assy. The water bottle cap assembly is highlighted in the 3D model, as shown in Figure 20.

    You can change the highlight color by using the color swatch at the top of the Structure pane.

  2. At the top of the Model Tree, click the arrow next to the color swatch. Choose a color from the color swatches or create a custom color. We chose blue, as shown in Figure 21.

    You can also identify a part in the model by selecting the part in the 3D model in the document pane.

  3. In the 3D model in the document pane, select the body of the water bottle.
  4. In the Structure pane, notice that the Water_Bottle_V1 node label is highlighted. This is the part you selected in the 3D model.

Zooming in on a Part

Now try zooming in on a part with which you want to work. In the Structure pane, expand the Water_Bottle_Lid_Assy component, if necessary. Then select the Water_Bottle_Nozzle label. Right-click (Windows) or Control-click (Mac OS) to open the context menu, and choose Zoom to Part, as shown in Figure 22.

You can also use the Zoom tool on the 3D toolbar to zoom in on a part.

Isolating a Part

Suppose you want to isolate the nozzle so that you can see it more clearly and manipulate it independently of the rest of the model. The nozzle is still selected in the work area and in the Structure pane; click the arrow next to the Options button at the top of the Structure pane to expand the menu, and choose Isolate (see Figure 23).

All the other components are hidden, leaving only the nozzle displayed. You can use any of the tools on the 3D toolbar to manipulate this one part. Simply move the pointer into the work area to display the 3D toolbar.

Showing and Hiding Parts

Next, try showing and hiding various parts of the model to see details of the filter.

  1. In the 3D toolbar, expand the Views menu, and choose Front. In the Structure pane of the Model Tree, select the Water_Bottle_V1 label. Right-click (Windows) or Control-click (Mac OS) to open the context menu, and click Hide.

    Now you're viewing only the filter and the cap assembly.

  2. Use any of the tools on the 3D toolbar to manipulate the model.
  3. When you're finished, click the Default View button on the 3D toolbar to return to the default view.
