Two key-ins can be used to directly control the view camera — CAMERA ROLL and CAMERA PROJECTION:

• CAMERA ROLL [angle] — sets the roll (tilt) angle of the camera for a view. If no value is given for angle, then it is assumed to be zero. The angle also may be entered in the tool settings window, which appears when you enter the key-in. After entering the key-in, select the view required to have its angle set.
• CAMERA PROJECTION [ANGLE | ONEPOINT | TWOPOINT | THREEPOINT] — sets the projection mode for a view. If a projection mode is included in the key-in, then that projection mode is used. The projection mode also may be selected in the tool settings window, which appears when you enter the key-in. After entering the key-in, select the view required to have its projection mode set.
