If you need to preserve your 3D values, you'll need to convert your 'grid' to 3D features.</P><P></P><P>I haven't got ArcGIS at hand now to give you an example, sorry. Hopefully somebody else can.</P><P>Filip.</P></BODY></HTML> Mon, 01 Sep 2014 20:32:44 GMT https://community.esri.com/t5/3d-questions/splitting-3d-polygons/m-p/28842#M227 FilipKrál 2014-09-01T20:32:44Z
