Zoom

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

Zoom All

Zoom All image\Zoom_All_button.gif (a.k.a. zoom extents, zoom limits) will zoom the tunnel so that all entities in the view are visible.

Zoom In

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

Zoom Out

Zoom Out image\Zoom_Out_button.gif 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.
