Dialog Box: Scaling [ Input2 Menu]
Scaling and displacement operations do not apply to the actual values of corner coordinates and face coefficients, which are permanently set by axis lengths and the central distances of the faces. Rescaling and displacement apply only to the plotting coordinates in screen, dot-matrix or pen-plotter displays.
Scale mode . There are three mode of scaling:
Maximize size for each view . In this mode, the crystal is scaled in each orientation so that it is just smaller than the viewing area. The actual scale will therefore change whenever the crystal is rotated. Hard copy is scaled the same way and what you see is essentially what you get.
Universal maximum. In this mode, the crystal is scaled so that its maximum dimension is just smaller than the minimum dimension of the plotting areas; thus, rotations can be made without changing the scale and without going out of bounds. Again, hard copy is scaled the same way and what you see is essentially what you get.
Fixed scale factors. This suboption allows you to set the scale to a fixed number of inches or centimeters per central distance unit for the dot-matrix and/or pen plot, or simply to reduce or enlarge the image from the automatic scaling modes.
The Rescale factor applies only to the Maximize... and Universal... modes. Both these modes scale the drawing to the dimensions of the screen (window) or the frame, and then apply this rescale factor. When you click the up- or down-size (or "zoom") button in the Dialog Bar - Right ), this changes the rescale factor unless you are in the Fixed... scaling mode. (This is a change from pre-V6.0 SHAPE - formerly clicking one of these buttons when in the Maximize... or Universal... modes would switch to the Fixed... mode.
Scaling for the screen and normal printer output (Print command in the File menu) depends on the resolutions (dots per inch or centimeter), which are obtained from the software drivers for these devices. The correct scaling for a particular printer may not be attained until you have used that printer for the first time. Resolution for the printer may often be reset in the Print Setup dialog in the File menu. The resolution for the Pen Plotter is set in the Pen Plotter Settings dialog, and that for a direct PostScript printer is set in the Postscript Settings in the Settings menu.
The Dialog Bar - Right allows "zooming" or incremental adjustment of the scale factors.
When displaying symmetry operators in the 3D mode, scaling in the Maximize size or Universal maximum modes is based on the presumed maximum extent of symmetry elements, which in turn are based on the maximum distance for corners - the ratios governing the relative sizes of crystal and symmetry elements are set in the 3D Parameters dialog (Input2 menu). Thus the scaling for in the Maximize size mode is practically identical to that in the Universal maximum mode.
