The 3D Zoom In/Out tool moves the observer position along the line between the current observer location and the target location in the 3D view. The observer cannot be moved forward beyond the target location, but there is no limit to how far the observer can be moved backward. This is similar to looking at a tree and walking directly toward or away from it.
- In ArcScene, click the Zoom In/Out button.
The pointer changes to indicate the Zoom In/Out tool.
- Click the 3D view and drag it up to zoom out or down to zoom in.
The observer location is moved closer or farther from the target position, which is maintained at the same location in the center of the view.
