The xy/z/m extents (domain), tolerances, and resolution (how the data is stored internally) are all affected by the coordinate system. Because of that, if you want to change the coordinate system with existing data, the data should be reprojected or reloaded to get converted properly.&nbsp;</P><P></P><P>Melita</P></BODY></HTML> Tue, 11 Sep 2018 18:47:41 GMT https://community.esri.com/t5/coordinate-reference-systems-questions/feature-class-not-maintaining-coord-system/m-p/772164#M303 MelitaKennedy 2018-09-11T18:47:41Z Re: Feature Class Not Maintaining Coord System https://community.esri.com/t5/coordinate-reference-systems-questions/feature-class-not-maintaining-coord-system/m-p/772165#M304 <HTML><HEAD></HEAD><BODY><P>Thank you, Melita.</P></BODY></HTML> Tue, 11 Sep 2018 19:24:38 GMT https://community.esri.com/t5/coordinate-reference-systems-questions/feature-class-not-maintaining-coord-system/m-p/772165#M304 JeffDavis7 2018-09-11T19:24:38Z
