User Guide
In some instances, the author of the PDF can set up a 3D model in the conversion settings so that clicking it automat­
ically displays the Model Tree.
Hide, isolate, and change the appearance of parts
Some 3D models are composed of individual parts. You can use the Model Tree to hide or isolate parts, zoom in to
parts, or make parts transparent. Parts that show in the 3D model appear in the tree with a check mark next to them.
A B C D
Manipulating parts
A. Selected part B. Hidden part C. Isolated part D. Transparent part
1 In the 3D model, use the Hand tool to click the part you want to manipulate. If a preference setting prevents you
from using the Hand tool, use the Object Data tool (Tools > Object Data > Object Data Tool) to select parts. Or, select
the part in the Model Tree list.
2 From the Options menu in the top pane of the Model Tree, choose any of the following:
Note: The items that appear on the Options menu and the order in which they are listed depend on whether the selected
3D model is composed of just one part or multiple parts. Many of these options are also available by right-
clicking/Control-clicking a part in the 3D model.
Model Render Mode Changes the surface appearance of the entire 3D model according to the item you choose from
the submenu: Transparent Bounding Box, Solid, Transparent, Solid Wireframe, and so on.
Show All Parts Displays the entire 3D model.
Fit Visible Displays all visible parts and centers them in the view.
Display Bounding Box Displays the box that encloses the 3D object or selected parts of the model.
Set Bounding Box Color Changes the color of the bounding box. Choose this option, select a color, and then click OK.
Hide Displays the model without showing the selected parts. You can also select and deselect check boxes in the top
pane of the Model Tree to hide and show different parts.
Isolate Displays only the selected part, hiding all others.
Zoom To Part Changes the center focus from the entire 3D model to the selected parts. This setting is especially
useful for rotating a part, allowing the rotation to occur around the part’s center focus rather than that of the entire
model.
Transparent Displays a see-through version of the selected part.
Export As XML Creates a separate XML file of either Whole Tree or Current Node of the 3D model.
Note: If the 3D model was created to include Product Manufacturing Information (PMI), options for showing and hiding
the PMI may be available on this menu.
