Chapter 13 Set and Criteria Selection

The crit_subel command establishes topologic constraints on objects to be
selected.  To be selected, an object must be a topologic element of a member of
the specified set.

crit_subel

    Criteria: topologic members of the specified set.

         crit_subel s

    This command establishes criteria requiring that an object must be an
    element of an object in the set specified (s).  A segment is an element of
    a polygon if it makes up part of the boundary of that polygon.  A node is
    an element of a segment if it is an endpoint of that segment.   A node is
    an element of a polygon if it is an  element of a segment which is an
    element of that polygon.   Every object is a subelement of itself.  An
    exterior (island  perimeter) is a subelement of its parent polygon.  When
    multiple crit_subel entries exist, only one must be true for an object to
    be included in the target set.  Assembly is required.
