Dialog Box: Centering/Displacement [ Input2 Menu]
Automatic centering will center the crystal in the current viewing area. This is done for each view, and any displacements entered under Constant Displacements are ignored.
In most cases, the easiest way to scale and position a drawing onto a printed or typed page is to use the frame options in the Print command or other options in the File . However, the displacements in this section can be used to position the drawing within the frame defined in those suboptions.
The displacements are used only in plotting and are not actually part of the corner coordinates. Note that the center of rotation is not changed by these displacements - that is, the crystal is always rotated about its own zero of coordinates. Thus any desired rotations should always be made before using displacements.
The Dialog Bar - Right ( Display menu) allows incremental displacements, and centering of the viewing area on a particular projection point in the crystal. Displacements made there will affect the displacements in this dialog (Centering/Displacement ), and may be removed here.
The Scale Grid command in the Display menu is useful for showing the actual scaled location of the crystal and in estimating displacements.
