Zoom

The Zoom options only apply to the display of the tunnel in the Tunnel Section View. The Zoom options are available in:

• the toolbar
• the Tunnel Section sub-menu of the View menu
• the default right-click menu on the Tunnel Section View
• the F2, F4, F5 function keys
• rotate mouse wheel forward or backward

Zoom All

Zoom All (aka zoom extents, zoom limits) will zoom the tunnel so that all entities in the view are visible.

Zoom In

Zoom In will increase the magnification so that the new view area is 90% of the old view area.

Zoom Out

Zoom Out will decrease the magnification so that the new view area is ~111% of the old view area.

TIP: if you have a mouse with a wheel, you can Zoom In by moving the wheel forward, and Zoom Out by moving the wheel backward.
