Zoom Preferences

The Zoom preference in the 3D Viewer Preferences dialog offers the following options for zooming with a wheel mouse button:

• Viewport Center: to zoom in and out along the 3D scene viewpoint center regardless of the current cursor position. This setting is the default and reflects the legacy zooming behavior.
• Cursor Position: to zoom in and out along the current cursor position.

These settings do not change the behavior of the Zoom Up and Zoom Down buttons on the Basic Viewing and Standard Viewing toolbars to zoom in and out along the 3D scene viewpoint center.
