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 .
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.
