Zooming
Figure 1. Zoom Toolbar
The following magnification functions are provided in Terrain for zooming in the Graphics Windows:
Zoom Double - magnifies the view by 200%, or reduces the scale by a factor of 2 (see Lock Scale button)
Zoom Half - magnifies the view by 50%, or increases the scale by a factor of 2 (see Lock Scale button)
Zoom In - allows you to create a zoom window using left mouse click and drag
End Zoom - resets magnification back to 100%
Zoom Extents - sets the view to the extents of the drawing
Pan - scrolls the view using left mouse click and drag
Scale ComboBox - allows you to select or type a scale for the view
Lock Scale - toggles between zooming by magnification or zooming by scale
These functions can be accessed either through the View - Zoom/Pan menu or through their tool bar buttons.
Note: the middle and/or roller mouse buttons have dedicated Zoom/Pan functions. The roller zooms while middle mouse click and drag pans (the roller is a button too). Some mouse software will override these functions.
