When placing spot elevations, and clicking on a contour line with the helpful Z elevations (I think that's how this works), the spot automatically shows the elevation, but in inches. For example, clicking on the 75' line shows an elevation of 900, which is how many inches it takes to reach 75'. My drawing units, and the xref units, are set to architectural inches. The contour lines are in the xref. Is it truly calculating inches? Will that affect hydraulic calcs? How do I make it show feet? I just enter things manually, but it sure is nice to use the contour lines.

Thanks!
