How do I clip a feature and get the right data in the attribute table? Do I use a different tool? I have ArcInfo. I wasn't sure where to post this question. Thanks.</SPAN></BODY></HTML> Thu, 06 May 2010 15:35:20 GMT https://community.esri.com/t5/geoprocessing-questions/how-do-i-clip-data/m-p/194803#M6653 LindseyWinn 2010-05-06T15:35:20Z Re: How do I clip data?! https://community.esri.com/t5/geoprocessing-questions/how-do-i-clip-data/m-p/194804#M6654 <HTML><HEAD></HEAD><BODY><SPAN>Do you mean you have numeric fields and you want a proportional value in you ouput row, based on the area of the shape after clipping?
