If you are looking for an ArcObjects solution you will find the answer if you search the archived esri forum (forums.esri.com) or get an answer if you post of the esri forum. – Hornbydd May 9 at 11:23
I agree and thanks. I am looking for efficient solution for my case. If any ESRI experts can help me would be great. – iamlaksh1 May 10 at 17:05
@iamlaksh1 What is meaning of "percentage overlap"? Number of the intersecting Feature? Or, percentage of overlapping area for each Feature? – Darksanta May 11 at 5:59
% of overlapping area between the polygons. – iamlaksh1 May 13 at 14:38
