The navigation tool allows you to examine documents in three different modes: Examine, Walk, and Fly Mode. You also have the features of zooming, panning, rotating, view displays, and visualization.

Navigating allows you to manipulate a document in the viewer, providing different visual perspectives.  You  can also utilize the ViewerSpace, which provides additional viewpoints.

The Examine Mode allows you to examine a document from two different perspectives, internal and external. You can also change your orientation around objects in the document.

The Walk Mode allows you to navigate about a document along the horizontal plane. A simulation of walking through a structure, moving forward, backward, turn right and turn left.

The Fly Mode allows you to move about the document along the horizontal view plane. You have the options to move upward, downward, forward, backward, turn right and turn left.

Zooming allows you to move the document closer or farther away in the view space. It is also possible to select a specific area and expand the view.

Panning is a feature that allows you to move across the ViewerSpace.

Rotating is a feature that allows you to move documents about the vertical and horizontal axes.

Fitting All In Viewer displays the entire set of documents in the full ViewerSpace.

Displaying the Previous View allows you to manipulate documents. You can save views as they are created and retrieve in the current view.

Displaying the Next View allows access to any view that was created subsequently to the current view.

Set the Shading with Material and Edges is a feature that allows you to change the visual characteristics of the document in the ViewerSpace. This feature provides different perspectives of the document.

Predefined Views is a feature allowing predefined view points to a document in the ViewerSpace.

The following directions and information will demonstrate the navigating feature in a document.

There is now a Compass in the Web Viewer.

• The Compass serves to indicate the orientation of your viewer content.
• It can also be used to rotate the viewpoint by dragging the orientation point.

When navigating in 3D, the Navigation Mode enables you to examine your documents in three different modes: Examine, Walk and Fly Mode.

When you enter either Walk or Fly mode, the projection mode is automatically set to perspective. While you are navigating in these modes, it will not be possible to modify the projection mode.     

Examine is the default navigation mode. You can examine your document as you would from the outside by moving around the document's perimeter (rotate), or as you would from within, modifying your orientation (pan) or moving closer to different objects (zoom in, zoom out).

1. In the View toolbar, click the Navigation Mode selection button and select the Examine Mode button from the proposed navigation list.

2. Examine your document as desired using the Zoom, Rotate and Pan commands.

In Walk mode, you can walk forward and backward as well as turn right or left as you walk along the horizontal plane.

Note: it is easier to walk through documents in contexts where you would find a virtual ground, e.g. in buildings, planes or ships.

1. Click the Navigation Mode selection button and select the Walk Mode  button from the proposed icon list.

2. Press and hold down the Middle Mouse Button to define the horizontal view plane.
   A green arrow appears and is oriented in the direction in which you will walk.
   
   

3. While holding the button down, drag to the left or to the right, to determine the direction in which you wish to walk.
   The arrow is re-oriented in the direction in which you will walk.
   
   

4. When you are oriented in the direction in which you wish to walk, click the Left Mouse Button while still holding the Middle Mouse Button down to begin walking.
   You begin to walk forward in the chosen direction.

5. Still holding the Middle Mouse Button down, drag left or right to change direction.
   Dragging to the left lets you view the object as if you had turned your head to the left; dragging to the right produces the same effect in the opposite direction.

6. Drag the cursor back towards the center of the view to continue your walk forward in the new direction.

7. Click the Left Mouse Button again to reverse direction.
   You begin to walk backwards, away from the target.

Pressing the Page Up and Page Down keys modifies your speed. The speed is indicated under the green arrow and in the status bar.

In fly navigation mode, you can move upward or downward on any horizontal view plane as you move forward or backward, turn right or left.

1. Click the Navigation Mode selection button and select Fly Mode button from the proposed icon list.

2. Press and hold down the Middle Mouse button to define the initial horizontal view plane.
   A green arrow indicating the direction in which you will be flying appears along with a circular target located at the center of the view.
   
   

3. While holding the button down, drag to the left or to the right to determine the direction in which you wish to fly.
   The arrow is re-oriented in the direction in which you will walk.
   
   

4. When in the direction in which you prefer to fly, click the Left Mouse button while still holding the middle button down to begin flying.
   You begin to fly forward in the chosen direction.
   The speed at which you first approach the object depends on the initial distance from the object, and is calculated automatically. The speed is optimized so that you reach your target in approximately 10 seconds.

5. While holding the Middle Mouse button down, drag left or right, or up or down, to change direction.
   You fly in the direction in which you drag. The further you drag away from the center of the view, the greater the change in direction.

6. Drag the cursor towards the center of the view to continue flying forward in the new direction.

7. Click the Left Mouse button again to reverse direction.
   You begin to fly backwards, away from the target. When flying backwards, the up and down directions are reversed.

Pressing the Page Up and Page Down keys modifies your speed. Speed is indicated in the status bar.

Zooming enables you to move closer to the documents that you are viewing in the ViewerSpace or to move further away.

1. Click Zoom In Out button and drag upward to zoom in or downward to zoom out. By using the Zoom button, you
   can move closer or further away from the content of the viewer.

In Examine mode, you can use the following shortcut to zoom interactively:

1. Press and hold the Middle Mouse button.

2. Click and release the Left Mouse button.

3. Release the Left Mouse button.

4. Drag the pointer upward to zoom in or downward to zoom out.

5. Release the left mouse button to discontinue.

Zooming into a designated area enables you to draw a rectangle around the portion of the document that you wish to zoom.  That portion will then fill the entire ViewerSpace.

1. Click the Zoom Area   button.

2. Hold down the Left Mouse Button and drag the mouse downward and toward the right in order to designate the area into which you wish to zoom. 
   A rectangle indicates the designated area.

3. Release the left mouse button. You will immediately zoom into the designated area upon release. The designated area will fill the entire ViewerSpace.

Panning enables you to move transversally across the ViewerSpace.

1. Click the  Pan button button.

2. Press the Left Mouse button and drag the pointer to the left or to the right.
   Your eye moves transversally left when you drag the pointer to the right or transversally right when you drag the pointer to the left.

3. Release the left mouse button to discontinue.
   

In Examine mode, you can use the following shortcut to pan interactively:

1. Press and hold the Middle Mouse button.

2. Drag the pointer vertically or horizontally to pan across the document.

3. Release the left mouse button to discontinue.

Rotating enables you to turn your documents around the vertical or horizontal axis.
