Default appearance

Wireframe rendering mode
C.
Colored lighting
D.
Different background color
❖
Use items on the 3D toolbar to make any of these changes:
•
To change the rendering mode, choose an option from the Model Render Mode pop-up menu
• To view an orthographic projection, click the Use Orthographic Projection button . An orthographic projection
effectively removes a dimension, preserving the size ratio between objects but giving the 3D model a less realistic
appearance. Click the button again to use perspective projection.
• To turn lighting on or off or to change lighting, choose an option from the Enable Extra Lighting pop-up menu
•
To change the background color, click the arrow next to the Background Color swatch and choose a color.
Note:
Model rendering modes, lighting schemes, and background color options are also available by right-
clicking/Control-clicking the 3D model. Model rendering modes also appear under the Options menu on the Model Tree.

Model Tree overview
The Model Tree appears in the navigation pane on the left side of the work area. You can also open the Model Tree
by clicking the Toggle Model Tree button
on the 3D toolbar, or by right-clicking/Control-clicking the 3D model
and choosing Show Model Tree.
Note:
Using the Model Tree requires version 7.0.7 or later of either Acrobat or Adobe Reader. Users with earlier versions
can interact with 3D models but not with the Model Tree.
The Model Tree has three panes, each of which displays a specific type of information or controls.
Structure pane
The topmost pane shows the tree structure of the 3D object. For example, a 3D object depicting a
car may have separate groups of objects (called nodes ) for the chassis, engine, and wheels. In this pane, you can move
through the hierarchy and select, isolate, or hide various parts.
Product Manufacturing Information (PMI) appears as a group of items on the same hierarchical level as its related
object or assembly.
