Navigating in Walk Mode

• Beginner's mode
• Advanced mode for experienced users.

Before using the Walk navigation mode, you must be in a perspective view (View->Render Style->Perspective). If you attempt to activate Walk mode, you will be prompted to switch to a perspective view.

1. Select  View->Navigation Mode->Walk.

The icons used in the beginner's walk mode appear in the View toolbar. (These commands are also available via View->Modify in the menu bar.)

2. Click the Turn Head icon in the View toolbar then drag (left mouse button) to define your starting position (the direction in which you look at the object).

3. Release at desired location.

4. Click the Walk icon , then click the left mouse button to begin to walk.
   You begin to walk straight forward in the chosen direction. A green arrow appears along with a circular target located at the center of the view. The number  below the arrow specifies the speed at which you are walking.

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 the point you target in approximately 10 seconds.

5. Still holding the left button down, drag to the right or left to change direction.

You walk in the direction in which you drag. The further you drag away from the center of the view (represented by the circular symbol ), the greater the change in direction.

Dragging to the left lets you view the object as if you had turned your head to the left; dragging to the right lets you view the object as if you had turned your head to the right.

As you drag, the shape of the arrow changes to reflect the direction in which you are walking.

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

7. To modify your speed, click the Accelerate  or Decelerate   icon one or more times.

8. To continue your walk, click the Walk icon again and then click in the view.
   Notice the different speed at which you now walk.

9. To return to the default navigation mode, click the Examine mode icon in the View toolbar.

You can also set mouse sensitivity and collision detection using the appropriate options in the Visualization tab, accessed via the Tools->Options command. For more information, see the Infrastructure User's Guide.

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

1. Select View ->Navigation Mode ->Walk.

2. Press and hold down the Middle Mouse button to define the horizontal view plane.

3. Still holding the button down, drag to the left or to the right to determine the direction in which you wish to walk.

4. In the Walk mode, press and hold down the Middle Mouse button until you've finished navigating.

5. When in the direction in which you wish to walk, click the left mouse button to begin walking.
   You begin to walk forward in the chosen direction.

A green arrow indicating the direction in which you are walking appears along with a circular target located at the center of the view, as in Beginner's walk mode.

6. Still holding the middle 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.

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

8. Click the Left Mouse button again to reverse direction.

You begin to walk backward, away from the target.

Note: The left and right are now defined as if you were walking away from the target with the your back towards it.

You can also set mouse sensitivity and collision detection using the appropriate options in the Visualization tab, accessed via the Tools->Options command. For more information, see the Infrastructure User's Guide.
