OK I have an interesting question for yall.
Scenario: Created a surface from my point cloud. The current coordinate system is set to UTM83 Zone 14 Meters and my drawing units is set to meters also.The surface elevations are correct.
Problem: When I extract contours from my surface the elevations of my extracted contours is in the wrong datum. For example my surface contour is 640 but my extracted contour is 192? I was curious why this happens?
