If you want to get volume differences (between this level plane and the tin), the polygon has to have an "elevation" attribute so you can use the Polygon Volume tool.</SPAN><BR /><BR /><SPAN>Good luck,</SPAN><BR /><SPAN>Neil</SPAN></BODY></HTML> Mon, 16 Sep 2013 11:55:12 GMT https://community.esri.com/t5/3d-questions/sea-level-rise-in-arcscene/m-p/471649#M2862 NeilAyres 2013-09-16T11:55:12Z
