I'm using version 10.1.2. I just set the Mask in the Raster Environments as you suggested. I set it to a raster with the same extent and grid size that I need but it didn't work. </SPAN><BR /><BR /><SPAN>Cheers anyway</SPAN><BR /><SPAN>Rob</SPAN></BODY></HTML> Fri, 28 Mar 2014 18:42:31 GMT https://community.esri.com/t5/geoprocessing-questions/converting-polygons-to-raster-that-are-usable-for/m-p/682543#M22658 RobertHoltom 2014-03-28T18:42:31Z
