Arc4You Poly Clean 1.0.0.3

With this extension for ArcView 3.x you can clean the topology of polygon themes. All possible errors like destroyed or overlapping polygons as well as gaps between the polygons can be cleaned. You should clean a polygon theme after importing (e.g. from ARC/INFO Coverage or AutoCAD drawing) as well as after editing or geoprocessing it (e.g. intersecting polygon themes using GeoProcessing Wizard or XTools). Particularly before final data transfer or conversion into a ARC/INFO Coverage this cleaning should happen.

Manual

When you load the extension into your ArcView project, the new button will appear in the button bar.
Click on this button to analyze and clean the active polygon theme.
