Ensure the selected features form contignous rings and overlap the polygons".</SPAN><BR /><BR /><SPAN>The polylines are indeed not forming continous rings in many cases, e.g. because they end at the end of my study area.</SPAN><BR /><BR /><SPAN>David</SPAN></BODY></HTML> Wed, 18 Sep 2013 14:21:51 GMT https://community.esri.com/t5/data-management-questions/cut-very-many-polygons-by-very-complex-polylines/m-p/81708#M4736 DavidLoibl 2013-09-18T14:21:51Z Re: Cut (very many) polygons by (very complex) polylines https://community.esri.com/t5/data-management-questions/cut-very-many-polygons-by-very-complex-polylines/m-p/81709#M4737 <HTML><HEAD></HEAD><BODY><SPAN>David,</SPAN><BR /><BR /><SPAN>I have a feeling those 2 tools are as good as it gets.
