I have z values in us feet (xy in state plane/us feet) and when i use the height measurement tool in arcscene the bottom of the well is 4 times as deep as the true bottom z value (true depth is 2000 us feet and arcscene is 8,000 feet). I dont have a vertical datum defined but I tried that and it does not change the results.</SPAN><BR /><BR /><SPAN>my z values are in us feet but are calculated to reference mean sea level below the KB (an above ground point on the drill rig) so i guess this would be a custom datum, but it's not defined. if xy and z are in feet should it matter?</SPAN></BODY></HTML> Fri, 04 May 2012 23:16:25 GMT https://community.esri.com/t5/3d-questions/z-values-differ-from-height-measure-tool-in/m-p/244917#M1473 AmyKlug 2012-05-04T23:16:25Z Re: z values differ from height measure tool in arcscene https://community.esri.com/t5/3d-questions/z-values-differ-from-height-measure-tool-in/m-p/244918#M1474 <HTML><HEAD></HEAD><BODY><SPAN>For the Scene document, do all your your layers have the same projection and coordinate system?&nbsp; It seems since you have it as being much greater that the units are still off.&nbsp; I would confirm that values are as expected (feet in xy and feet in z).&nbsp; There is a bug report out there, but it mentions that the meters selection is actually measuring feet, not the inverse.&nbsp; For specific help, I recommend opening a Support Incident to test with your data.&nbsp; I do not think the absence of a custom vertical datum is causing the issue.</SPAN></BODY></HTML> Mon, 07 May 2012 10:43:53 GMT https://community.esri.com/t5/3d-questions/z-values-differ-from-height-measure-tool-in/m-p/244918#M1474 JeffreySwain 2012-05-07T10:43:53Z Re: z values differ from height measure tool in arcscene https://community.esri.com/t5/3d-questions/z-values-differ-from-height-measure-tool-in/m-p/244919#M1475 <HTML><HEAD></HEAD><BODY><SPAN>I converted the value the tool gave me for feet to meters and got the correct value in feet.
