Walk
Click the 3D View | View | Walk command or the 
button to enter walk mode. The Walk camera position and orientation is saved when you exit walk mode and restored when you reenter walk mode. While in walk mode, the keyboard and mouse are used to walk along the surface in the 3D view window. The 3D view window must contain at least one surface or volume to enter walk mode.
Walk Mouse Controls
Click and drag in the 3D view window to move and rotate the view.
- Drag the mouse up to move forward, or towards where the view is pointed.
- Drag the mouse down to move backward, or away from where the view is pointed.
- Drag the mouse right to rotate to the right, or clockwise.
- Drag the mouse left to rotate to the left, or counterclockwise.
- Roll the mouse wheel forward to increase the elevation of the camera.
- Click and drag down with the mouse wheel or middle-mouse button to increase the elevation of the camera.
- Roll the mouse wheel backward to decrease the elevation of the camera.
- Click and drag up with the mouse wheel or middle-mouse button to decrease the elevation of the camera.
Walk Keyboard Controls
Press the ARROW or WASD keys to move and rotate the view. Use SHIFT and CTRL to change the camera elevation.
- Press UP ARROW or W to move forward, or towards where the view is pointed.
- Press DOWN ARROW or S to move backward, or away from where the view is pointed.
- Press RIGHT ARROW or D to rotate to the right, or clockwise.
- Press LEFT ARROW or A to rotate to the left, or counterclockwise.
- Press SHIFT to increase the camera elevation.
- Press CTRL to decrease the camera elevation.
Walk with Multiple Surfaces
The 3D View | View | Walk command may be used with a 3D view that includes more than one surface. When the surfaces are contiguous, you may walk from one surface to another while in walk mode.
It is not recommended to use the Walk command in a 3D view with two or more surfaces that occupy the same XY extents but have significantly different Z values. When this is the case, the camera elevation follows the highest surface (largest Z values).
Walk through a 3D Volume
The 3D View | View | Walk command may be used with a 3D view that includes only a 3D grid volume. When you walk through a 3D volume you will start walking at the middle Z value and will remain on that plane until you choose to move the camera up or down.
When both a 2D grid surface and a 3D grid volume are present in the model, you can walk along the surface or walk on a plane through the volume by selecting the object of interest before clicking the 3D View | View | Walk command.
