3D Compass

  1. Select the camera to be moved  in the specification tree.
    The 3D representation is shown in the geometry area.

Note: To move the camera, you will attach the 3D compass to the 3D camera representation. If you cannot see the 3D representation, click the camera in the specification tree and select Camera object -> Hide / Show Representation from the contextual menu. 

 

  1. To attach the 3D compass to the 3D camera representation, press and hold down the left mouse button on the red square of the 3D compass, then drag the 3D compass to attach it to the camera representation.

Notice that the compass changes appearance as you drag it.
Pointing to a line coming from the eye automatically snaps the compass to the eye and pointing to one of the sides of the viewport snaps the compass to the target.

You can attach the 3D compass to two different positions of the camera representation as shown below: the eye and the target.
