Chapter 13 Set and Criteria Selection

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

crit_superel

    Criteria: has an element which is a member of the specified set.

         crit_superel s

    This command establishes criteria requiring that an object must have as an
    element 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 superelement of itself.  A normal
    (interior) polygon (or the map border) is a superelement of its parent
    islands.  When multiple crit_superel entries exist, only  one must be true
    for an object to be included in the target set.  Assembly is required.
