Two fly modes are available:

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

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

Note: Beginner's fly mode commands are single-action commands. Releasing the mouse button means you exit the command. You can only move forward in beginner's fly mode.

1. Click the Fly Mode icon in the View toolbar or select View->Navigation Mode->Fly.
   The icons used in the beginner's fly 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 Fly icon , then click the left mouse button to begin to flying.
   You begin to fly forward in the chosen direction.

A green arrow appears along with a circular target located at the center of the view.
The figure below the arrow specifies the speed at which you are flying.

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, 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 (represented by the circular symbol), the greater the change in direction.

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

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

7. To modify your speed, click the Accelerate or Decelerate icon one or more times, then click the Fly icon again followed by the left mouse button to pursue your fly.
   Each click on the icon increases or decreases the speed by approximately 40%.
   

Pressing the Shift key and dragging lets you bank left or right.

You can use the option "Gravitational effects when navigating" in the Visualization tab, accessed via the Tools->Options command, to fix the X, Y or Z axis during navigation. While turning in Fly mode, this creates the impression that the user viewpoint tilts or banks with respect to the fixed axis, as in a real plane.

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.

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

1. Click the Fly Mode icon in the View toolbar or select View->Navigation Mode->Fly

2. Press and hold down the middle mouse button to define the initial 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 fly.

4. In the Fly mode, press and hold down the middle mouse button until you've finished navigating.

5. When in the direction in which you wish to fly, click the left mouse button to begin flying:

You begin to fly forward in the chosen direction.
A green arrow appears along with a circular target located at the center of the view, like when using the beginner's fly mode.

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.

6. Still holding the middle 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.

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

Each press of the key increases or decreases the speed by approximately 40%.

8. 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 are reversed.

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.
