Plan View Objects based on External Data


External data in this context refers to data not stored in the principal database.  These data sources are ASCII comma delimited files.  In most cases, they consist of a set of coordinates, followed by a numeric value (i.e., x, y, v).  In some instances, such as 3d contouring and 3d classed-post, they also include an elevation value (i.e. x, y, z, v)
