I will try using that settings. In the meantime I created this convoluted workaround where I create a whole bunch of text files, they all have headers, read the second line and then append that to a new file. Quite a pain but it worked. When I get the chance I'll re-code it to make it simpler. <span class="lia-unicode-emoji" title=":grinning_face_with_smiling_eyes:">😄</span></SPAN></BODY></HTML> Tue, 18 Jan 2011 20:09:52 GMT https://community.esri.com/t5/arcobjects-sdk-questions/running-surfacevolume-multiple-times/m-p/382716#M10133 MatthewBuchanan 2011-01-18T20:09:52Z
