Top views

TerraPhoto displays raster images only in top views. A top view is an orthonormal view where usually, the north axis points upward on the screen. However, a top view can also be rotated around its z-axis.

To rotate a view to top rotation:

msrotateview1. Select the Rotate View tool from the MicroStation View tool box.

The Rotate view dialog opens.

2. Select Top in the Method list.

3. Place a data click inside the view.

This changes the view to a top view where north direction points upward on the screen.

You can use the same tool to rotate the view around its z-axis. The method described below is especially handy when you have a corridor-like project area which you would like to run horizontally across the screen.

To rotate a view around the z-axis:

msrotateview1. Select the Rotate View tool from the MicroStation View tool box.

The Rotate view dialog opens.

2. Select 3 Points in the Method list.

3. Place a data click inside the view to define the start point for a direction line.

4. Place a data click inside the view to define the end point for a direction line.

The direction line defines the horizontal direction of the rotated top view.

5. Place a data click inside the view to define the upward direction on the screen.

This rotates the view so that the given direction line runs from left to right on the screen.
