- Molecules and ions will be included in a packing diagram (i.e. a display showing one or more unit cells or fractions of unit cells) if their geometrical centres lie within the current packing ranges.
- When a new structure is loaded, the packing range along each crystallographic axis is automatically set to 0.0 to1.0. This means that, by default, packing diagrams will include molecules whose centroids have fractional crystallographic coordinates (see Fractional Coordinates) falling between 0.0 and 1.0 in all three (a,b,c) directions.
- Packing ranges can be edited (see Section 9.3.3) and therefore packing diagrams can be customised to show any number of unit cells in any direction.
