The view mode buttons allow you to quickly switch between a 3D and 2D view. With these view modes you can go from a virtual reality appearance (3D) to an orthographic map view (2D) and vice-versa in a single-click. The set view mode impacts how your data appears to you but also how you navigate around.
The illustration below shows a rock wall from the side (left) and from the top (middle). Both pictures are made in 3D view mode. The right picture shows the same location in the 2D view mode.
Changing the view mode
The view modes are accessible in the ribbon through the Navigation tab.
The status bar (bottom right corner) has quick access buttons that allow you to change view mode without switching tabs.
You can change the view mode at any time with the following keyboard shortcuts:
|Alt+K||Change viewport to 3D view mode|
|Alt+M||Change viewport to 2D view mode|
3D view mode
The 3D view mode shows the data as you would observe them when you would be on site, as how your eyes perceive reality. That makes the 3D view mode a good choice for most of your surveying work. You can observe every position in a three-dimensational context and create your points and breaklines at the correct location.
However, in some use cases, the 2D view mode is a better option.
2D view mode
The 2D view mode shows the data as you would be directly above any location of your data. The data will appear to you as on a map and all your vector data will be shown on top of the terrain.
That makes the 2D view mode a good choice when you want to take a screen capture for a report (overview of stock piles) or when some of your data is covered by the 3D terrain. In the illustration below, the yellow lines that go under the bridge would not be visible in the 3D view mode.
While you lose the 3D component in the 2D view mode, you can still keep the link with the terrain topography by using the terrain lenses. The illustration below combines the elevation color, contours and hillshade lens. Although the picture is made in 2D view mode, you still get a very good understanding of the topography.
