How I got around it was to run copy feature on the output of the iterator and copy your single polygon to a <EM>in_memory</EM> workspace, so you have dataset with&nbsp;a single polygon in it. It is then this polygon that feeds into the extract by mask tool. As this is a dataset with a single polygon it takes on the <STRONG>extent</STRONG> of that single feature rather than the whole dataset thus your output raster will have a much smaller extent.</P></BODY></HTML> Wed, 11 Sep 2019 11:52:01 GMT https://community.esri.com/t5/modelbuilder-questions/error-extract-by-mask/m-p/834800#M1148 DuncanHornby 2019-09-11T11:52:01Z
