Thanks, you help was greatly appreciated. In my specific case the attribution is the most important part of the data. Is there anyway to keep the attribution attached to the data throughout the transformation process (from pts. to polyline to polygon)?
Give an example of an "Attribution" from a set of points to a polygon. Are you talking about one attribute or many attributes? Do all of the points that make up the Polyline or Polygon have the same attribute value for every point or does this involve a one to many relationship? If the relationship is one-to-one for all attributes then transferring the attributes should be relatively simple. But if each attribute has a one-to-many relationship then you must use aggregation tools and you ought to have an ArcInfo license to use the full set of tools that handle that relationship in GIS. The methods for creating the polyyline and polygon should preserve one value from the points that aggregated them into the polyline or polygon that can should be usable as a join value. If not then a Spatial Join may be needed, but I would be surprised if that was necessary. Anyway, you have not given enough information.
