Walkthrough

The tool operates in perspective projection. Four modes, the Viewer Height parameter, and various modifier keys provide flexibility to manipulate the viewer position and view angle before and during the walkthrough.

Mode	Description
Walk	Uses the mouse to move the viewer through the drawing
Look Around	Uses the mouse to change the view angle up, down, right, and left while the viewer remains stationary
Elevator	Uses the mouse to raise and lower the viewer height
Gamer	Similar to many video games, uses the keyboard (to move) and mouse (to steer left and right, and look up and down) to move the viewer through the drawing
Preferences	Specifies options for Gamer mode; see Viewing a Model in Gamer Mode
Viewer Height	Specifies the viewer height above the ground plane. This value updates automatically after Elevator mode is used; it also reflects the viewer height as set by any other viewing tool.

When the Walkthrough tool is in use, the Data bar displays the following information to help orient the view.

Data Bar	Description
Yaw	Displays the angle (0–360 degrees) between the walking direction and the positive Y axis, to describe the direction of movement in the active layer plane. A yaw of 90 degrees indicates movement in the direction of the positive X axis. A yaw of 180 degrees indicates movement in the direction of the negative Y axis.
Pitch	Displays the viewing angle. A value of 0 degrees indicates that the viewer is looking straight ahead; a value of 45 degrees indicates that the viewer is looking up at an angle 45 degrees from horizontal.
Viewer X/Y/Z	Displays the position of the viewer relative to the active layer plane

If the floating Data bar is enabled, you can hide the Data bar during the walkthrough. Select Preferences and then select Hide Floating Databar.
