Dialog Box: Line Attributes [ Input2 Menu]
Back edges - those not visible if the crystal is opaque - may be specified as none (not shown at all), dashed or solid.
Dash length and dash ratio . The dashes are used for back edges of crystals and display of Crystal Axes. Length or repeat distance is in inches/centimeters, and the length factor is the actual length of the solid part divided by the repeat distance. Note that when using Frames in output the dash length remains the same - it may be desirable to decrease the length for very small plots.
Widths are specified in inches or centimeters (choice of units is in the Preferences dialog in the Settings menu). Values of 0.0 will give one-dot width. Output pertains to all types of non-screen output except pen plot. Widths of pen plots can only be changed by using different pens.
