When you walk through a model, you travel along the XY plane. When you fly through
a model, you are not constrained by the XY plane, so you appear to “flyâ€‌ over an area
in a model.

Use the Keyboard and Mouse Interactions to Walk and Fly

You can use a standard set of keys and mouse interactions to walk and fly through
a drawing. Use the four arrow keys or the W, A, S, and D keys to move up, down, left,
or right. To toggle between walk and fly mode, press the F key. To specify the direction
of the view, drag the mouse in the direction you want to look.

Display a Top View of a Model as You Walk or Fly

You can keep track of your position in a 3D model as you walk or fly through it. When
you start 3DWALK or 3DFLY, the Position Locator window displays a top view of the
model. A position indicator shows your location in relationship to the model, and
a target indicator shows the model you are walking or flying through. You can edit
the position settings in the Position Locator window before you start walk or fly
mode, or while you are moving in the model.

Specify Walk and Fly Settings

Specify walk and fly settings in the 3D Navigate panel on the ribbon or in the Walk
and Fly Settings dialog box. You can set the default step size, the number of steps
per second, and other display settings.

Animate Walk and Fly Navigation

You can create a preview animation of any navigation, including walking and flying
through a drawing. Create the preview to fine-tune your animation before you create
a motion path animation. You can create, record, play back, and save the animation.
