Overview

   GeometryBuilderFactory builds geometries based on input features which make up the 
   parts of the geometries built. For example, input surfaces can be used to build
   surface donuts and/or solids. Input solids can be used to build hollow solids, or solids 
   containing cavities.

Input Tags
   
   INPUT
   
      All input features.
      
Clauses
  
   GROUP_BY 
   
      Attributes used to group input features.

   LIST_NAME

      Specifies the name of the list of attributes that contains attributes of
      participating input features.

   DROP_HOLES

      Determines whether interior hole representations are additionally
      output.

   HOLE_ATTR

      Specifies the name of an attribute that contains a yes/no value for whether
      an output features is a hole or not.

   HOLE_LIST_NAME

      Specifies the name of the list of attributes that contains the attributes
      of all of the participating hole features.

   NORMAL_TOLERANCE

      If two planes are nearly co-planar, but their normals are slightly apart,
      use this clause to set a tolerance in degrees. 

   OFFSET_TOLERANCE

      If two planes are parallel, but slightly offset from one another, 
      use this clause to set a tolerance in ground units.

   MODE

      Specifies whether the input geometry should be build as surfaces
      or solids. 

Output Tags
   
   SURFACE
   
      Surface features that are constructed from input surfaces or lines.
   
   SOLID
   
      Solid features that are constructed from input surfaces and/or solids.

   UNUSED
   
      Input features that have supported geometries but were not used in geometry building.

   <REJECTED>
      
      Input features which have unsupported geometries.
