Navigating in Walk Mode

 In Walk mode, you can walk forward and backward (backward in advanced mode only) as well as turn right or left as you walk along the horizontal plane.
Two walk modes are available:

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

 Beginners Walk Mode

This task shows you how to navigate in beginner's walk mode.
Beginner's walk mode commands are single-action commands. Releasing the mouse button means you exit the command. You can only move forward in beginner's walk mode.
Open the document Platform.model.

  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.

  2. Click Turn Head 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 the desired location.

  4. Click Walk or select View > Modify > Walk Through, then click the left mouse button to begin to walking.

    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 figure 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, or up or down, 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 produces the same effect in the opposite direction.
    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 straight forward in the new direction.

  7. To modify your speed, click Accelerate  or Decelerate one or more times, then click Walk again followed by the left mouse button to pursue your walk.

  8. To return to the default navigation mode, click Examine Mode in the View toolbar.
You can also set mouse sensitivity and collision detection using the appropriate options in Tools > Options > General > Display > Navigation.
 

Advanced Walk Mode

This task shows you how to navigate through a document in Walk mode.
Before using the Walk navigation mode, you must be in a perspective view (select View > Render Style> Perspective).
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.
Open the document Platform.model.

  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.

    In the Walk mode, press and hold down the middle mouse button until you have finished navigating.

  4. 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 appears along with a circular target located at the center of the view, like when using the beginner's walk mode:

  5. 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.

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

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

  7. Click the left mouse button again to reverse the direction.

    You begin to walk backward, away from the target.

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

 
If you activated Collision detection in Tools > Options > General > Display > Navigation, then the green arrow turns red when a collision is detected, whether you navigate in beginner's or advanced Walk mode:
 
You can also set mouse sensitivity and collision detection using the appropriate options in Tools > Options > General > Display > Navigation.
