Just select the 2 lines as input and specify "POINT" as output type.&nbsp; The outputs will actually be multipoints but you can always dissolve them (Dissolve tool with the option Create Multi part features unchecked) to get back to points.</SPAN><BR /><BR /><SPAN>Christine Dartiguenave</SPAN><BR /><SPAN>Esri Water Resources Team</SPAN></BODY></HTML> Thu, 28 Mar 2013 22:22:05 GMT https://community.esri.com/t5/water-resources-questions/extracting-multiple-catchments/m-p/326098#M1569 ChristineDartiguenave 2013-03-28T22:22:05Z
