Error in arctoolbox: 'invalidtopology [INCOMPLETE_VOID_POLY] Solution

The following error occurs: Results do not look correct or operations fail with strange errors such: 'Invalid Topology [INCOMPLETE_VOID_POLY]' The preceding error may occur when you perform the following operations: Clip, Erase, Identity, Intersect, semantic rical Difference, Union, Update, Split Featureclass to Coverage, Dissolve, Feature to Line, Feature To Polygon, Integrate or ValidateTopology. Cause It is possible that tool outputs may be strange or incorrect because one or more features in your input feature class have geometry problems. Examples of geometry problems are: · Short segments · Null geometry · Incorrect ring ordering · Incorrect segment orientation · Unclosed rings · Self-intersections or empty parts Solution If you are seeing such errors or your output looks incorrect, the first step in assessing the situation is to runArcToolbox tool Data Management Tools-> Features-> Check Geometry. This tool will give you a list of the invalid features in the feature class and a short description of the problem. Features with problems can be fixed in one of two ways. Editing the feature class with the geometry problem, and fixing each individual problem identified. some of these problems (like non-simple geometry) can be fixed by double clicking the feature in the editor and saving the edits. RunningArcToolBox tool Data Management Tools-> Features-> Repair GeometryOn the feature class containing the problem features.
