So basically I want to do an "outside buffer". There is a buffer type that is supposed to do this but it's not working properly so I'm trying to use iterations to select each polygon, make a buffer and then erase the polygon out of the buffer.</SPAN><BR /><SPAN>It seems to iterate through the polygons but it gives me an error each time saying the input is invalid for the erase tool. </SPAN><BR /><SPAN>I'm sure the answer is simple but this is my first time trying to use iterations in model builder.</SPAN><BR /><SPAN>Thanks for any help anybody can give me. </SPAN><BR /><SPAN>Lorna</SPAN></BODY></HTML> Tue, 07 Jun 2011 17:44:11 GMT https://community.esri.com/t5/geoprocessing-questions/new-to-iterations-in-model-builder/m-p/391152#M13342 Anonymous User 2011-06-07T17:44:11Z Re: New to iterations in model builder https://community.esri.com/t5/geoprocessing-questions/new-to-iterations-in-model-builder/m-p/391153#M13343 <HTML><HEAD></HEAD><BODY><SPAN>Original User: Hornbydd</SPAN><BR /><BR /><SPAN>Lorna,</SPAN><BR /><BR /><SPAN>I'm just guessing here as I'm not at a v10 machine but I think the "clue is in the answer", I'm guessing the erase tool cannot handle the output of the feature iterator.
