Chapter 13 Set and Criteria Selection

The crit_type command establishes criteria based upon an object type.

crit_type

    Criteria: object type.
     
         crit_type c

    This command establishes criteria for set selection by object type.  When
    multiple crit_type entries exist, only one must be true for an object to be
    included in the target set.  Assembly is required.

    Options/arguments:

         c         Object type code, where:
                   0 = any node
                   1 = any segment
                   2 = any polygon
                   3 = node with 0 branches; an isolated point 
                   4 = node with 1 branch; a spur endpoint 
                   5 = node with 2 branches; a node on a simple island
                   6 = node with 3 branches; a junction node 
                   7 = node with 4 branches; a junction node 
                   8 = segment with 2 free (spur) ends; a free segment
                   9 = segment with 1 free (spur) end; a spur
                   10= segment with no free ends 
                   11= single links to islands (segment) 
                   12= segments between polygons with the same attribute
                   13= possible segment contour attribute sequence error
                   14= interior polygon
                   15= exterior polygon (negative area value) 
                   16= map border exterior polygon (negative area value)
    ___________________________________________________________________________
    Example(s):

    To establish set selection criteria for determining all objects which are
    single links to islands, enter:

         crit_type 11

    To establish set selection criteria for determining all spurs, enter:
     
         crit_type 9
