Multimedia and 3D models

Last updated 1/14/2015

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.
