Syntax

   @AddVertices((x|y|c1|c2|xy|c1c2|xy_uniform|c1c2_uniform),<interval>)

Arguments

   <axis>
   
      The first parameter controls the axis used to determine when vertices are 
      added. If xy is specified, then vertices will be added on the basis of the 
      2D length of segments. The x and y axes may be specified to generate tick 
      marks along each of them at multiples of the interval.
      
      Range: (x|y|c1|c2|xy|c1c2|xy_uniform|c1c2_uniform)
   
   <interval>

      The second parameter specifies the interval at which vertices are added. 
      It is used differently depending on the setting of the <axis> parameter. 
      If the <axis> is x or y, then the new vertices will be inserted into the 
      feature along the specified axis at each multiple of <interval>. If the 
      <axis> is xy, then new vertices will be inserted so no single line segment 
      in the feature is longer than the <interval>.
      
      The interval is measured in the feature's ground units.
      
      Range: Real Number

Description

   This function adds vertices to features. It interpolates new coordinates at 
   some specified interval. The interval may be along only one of the two 
   primary axes, or it may be along the length of the line segments.
   
   This function is often used to densify the vertices of a feature to prepare 
   it for reprojection. By adding vertices to long linear segments, the feature 
   better represents the original in a different coordinate system.
   
   When used with the x or y option, the function may also be used to add tick 
   marks to features along an axis at the specified <interval>.

TO BE RESOLVED

   c1, c2, c1c2, c1c2_uniform added to Syntax section above as values for <axis> 
   parameter, but not documented.
