To change the viewer height:
Click the Walkthrough tool from the Visualization tool set and click Elevator from the Tool bar.
The projection automatically switches to Normal Perspective.
Click the drawing and hold the mouse button while you move the cursor up or down. The Data bar provides real-time information about the viewer height.
The first click inside the drawing, indicated by a small cross, establishes the control point of the movement. The control point lets you manage the pace of the movement. The farther away from the control point the cursor moves, the faster the movement. Return the cursor to the control point to slow or pause the movement. To stop the operation, release the mouse button.
Alternatively, if you know the desired viewer height, set the value in Viewer Height on the Tool bar. This field can be edited in any mode.
