Both the Select menu and the Selection toolbox provide options for specifying which hierarchy is used for the Select Parents and Select Children commands.
There are two options for hierarchy:
):
Specifies that parent/child relationships exist between entities of similar types (i.e. grid
entities are parents and children of other grid entities and database entities are parents
and children of other database entities). This is the default option.):
Specifies that parent/child relationships exist between database entities (the parents) and
the grid entities constrained to them (the children).
The figures in the Select Parents and the Select Children sections of this User Manual outline in detail the parent/child relationships for every entity in both Standard Hierarchy and Constrained Hierarchy.
