Dialog Box: Save/Recover Orientation [ Rotation Menu]
The first two options will counteract all rotations made by the dialogs in the Rotation menu as well as any made on-screen with dialogs in the Display menu, and take you back to one of two settings. The original orientation means the orientation before any rotations, including the rotations of the Initial Orientation dialog in the Input2 menu, have been made. The initial orientation is that attained after the rotations of the Initial Orientation dialog - that is initital Cartesian rotations and initial clinographic rotations - have been made, if any of them were actually used. See also Coordinate Systems.
The third option will save the current orientation as initial Cartesian rotations, plus initial clinographic rotation if clinographic viewing is currently in effect. These settings can be viewed and changed in the Initial Orientation dialog in the Input2 menu.
Summary of orientation operations . After calculation, SHAPE first sets the c crystal axis parallel to the z viewer axis, and the a * crystal axis (perpendicular to b and c ) parallel to x . This is the original orientation. Next, the initial Cartesian rotations, if any, are applied. Finally, the clinographic rotations, if selected, are applied. This is the initial orientation.
