Note: You can also use the Hand tool to rotate an object. Ensure that Enable 3D Selection For The Hand Tool is selected
in the 3D panel of the Preferences dialog box.
Spin Turns a 3D model in parallel to two fixed axes in the 3D model, the x-axis and the z-axis.
Pan Moves the model vertically and horizontally only. You can also pan with the Hand tool: Ctrl-drag.
Zoom Moves you toward, or away from, objects in the scene when you drag vertically. You can also zoom with the
Hand tool by holding down Shift as you drag.
Walk Pivots horizontally around the scene when you drag horizontally. Moves forward or backward in the scene
when you drag vertically; maintains a constant elevation level, regardless of how you drag. The Walk tool is especially
useful for architectural 3D models. To change the walking speed, change the default display units in the Preferences (3D).
Note: The Walk tool is available when you select the Preferences setting that consolidates tools or when you right-click
the 3D model and choose Tools > Walk.
Fly Navigates through a model while maintaining the surface orientation. Right-click and drag inside the 3D
window. The Fly tool moves more slowly the closer you move toward an object. Drag the pointer right or left to turn.
To rotate the camera view, click the left mouse button inside the 3D window and drag to turn the camera view. To
return to the starting camera direction, move the mouse back to the initial click point.
Use the mouse scroll wheel to move rapidly backward and forward along the camera view direction. This functionality
is useful if you get lost within a model or fly into the surface.
Camera properties Defines the camera angle, alignment, and other properties that define the lens through which
a 3D model is viewed. Camera properties are components of views but are set independently.
3D Measurement Tool Measures part sizes and distances in the 3D model.
3D toolbar view controls
Default View Returns to a preset zoom, pan, rotation, and projection mode of the 3D model. Use the Options
menu in the View pane of the Model Tree to set a different view as the default. Or use the Manage Views command
on the 3D toolbar Views menu to set a different view as the default.
If an object ever moves out of your view, you have, in essence, turned your camera away from the object. Click the
Default View icon on the 3D toolbar to move the object back into view.
Views menu Lists any views defined for the current 3D model.
Toggle Model Tree Opens and hides the Model Tree.
Play/Pause Animation Plays or pauses any JavaScript-enabled animation. The Play/Pause Animation pop-up
menu opens a slider that you can drag back and forth to move to different times in the animation sequence.
Use Orthographic/Perspective Projection Toggles between displaying perspective and orthographic projection of
the 3D object.
Model Render Mode menu Determines how the 3D shape appears. For an illustrated guide, see “Examples of
model rendering modes” on page 303.
Enable Extra Lighting menu Lists the different lighting effects that are available to enhance the illumination of the
3D object. Experiment to get the visual effects you want.
Background Color Opens the color picker, which you can use to select a different color for the space surrounding
the 3D object.
Toggle Cross Section Shows and hides cross sections of the object. Click the pop-up menu to open the Cross
Section Properties dialog box. For more information, see
“Create cross sections” on page 307.
