12.3.2 View control
The View control provides pre-defined view of all data currently active in the 3D View. To zoom to pre-defined views
of specific scans, deployments, or stations, use other zoom buttons in the Control tab or in the Project tab.
Tap View to open the View dialog.
A choice of Perspective or Orthographic view is available.
• In Perspective view, the data can be freely rotated. Objects which are far away are smaller than those
nearby. A perspective viewpoint gives more information about relative distances and is often easier to view
as it is familiar from our real-life view of the world.
• In Orthographic view, the data is viewed from a fixed perspective. All edges perpendicular to the view
direction appear in proportion, at the same scale. Uniform perspective is particularly useful when analysing
data to see the floor level or the shape of a void from fixed viewpoints.
You cannot rotate data when Orthographic view is selected. The default rotating action will pan the data
instead.
When the Orthographic view is selected, gridlines are projected onto the 3D View. The Vertical Ruler and
Horizontal Ruler are displayed along the side and top of the screen, respectively.
An Orthographic options button appears in the top left of the 3D View. Tap the Orthographic options
button to open the Orthographic options dialog.
