Rotated Views

Rotated views are views that are rotated around the east axis. As a result, the z axis points in an upward direction which is the usual case for geospatial 3D visualizations. Depending on an additional rotation around the z axis, the north and east axes point into different directions. In Bentley CAD and Spatix, there are some predefined settings for certain view orientations:

•Front - north axis points into the screen, east axis points to the right, z axis points straight upwards.

•Back - north axis points towards the observer, east axis points to the left, z axis points straight upwards.

•Left - north axis points to the left, east axis points into the screen, z axis points straight upwards.

•Right - north axis points to the right, east axis points towards the observer, z axis points straight upwards.

•Isometric - Front setting rotated 45° counterclockwise around the z axis and towards the observer around the east axis.

•Right isometric - Front setting rotated 45° clockwise around the z axis and towards the observer around the east axis.

The following sketches illustrate the different view orientations. The first image shows the orientation of the coordinate axes in a top view while the other images show the orientation in the above described rotated views.
