Administrative Hierarchy

Below the zone level of the hierarchy, there are three common administrative elements that are only available for selection in the four applications under structures:

• Structure (STRU)

• Framework (FRMW)

• Sub-Frame (SBFR).

Section and panel elements can be created using grid storage mode which allows for the automatic creation of structural hierarchy elements. Refer to Section and Panel Storage for further information.

Elements created in grid storage mode refer to grid planes and are created as FRMW members. FRMW elements are created automatically when required.

STRU elements refer to a reference grid and are automatically created when the first element is positioned on a new reference grid (not associated with a STRU).

If the current element is a World, SITE or ZONE, elements are automatically created when the first element is positioned on a new reference grid (not associated with a STRU).
