Group Link

Set here the translation applied to the child object or list of objects.

When linking a group to another object, the translation is always applied to the child object: the group itself when linking above, the other object (group, plane, direction, atom, orbital, text) when linking below.

The final child position is given by this translation vector added to the child or parent origin, as defined by the Reference option. By default this is the child origin and the translation vector is 0.0, 0.0, 0.0, so no translation is applied.

When a list of groups is linked above, Reference is set by default to Child, so groups preserve their positions and are not superposed.

When a list of groups is linked below, each group will be linked to a new, automatically created, child object, and Reference is set by default to Parent, so childs remain near their parent groups and are not superposed.
