    Currently, I am trying to make a TIN from predefined contours of both the existing ground as well as the proposed ground so that I can perform volume computations. I am able to create the surface but the problem I am having is getting the units of the contours and the units of the surface to agree. For example, I was given a file from the surveyors that has contour lines with elevations ranging from 175 to 185 feet. When I make a TIN surface from the contours, it converts the elevations of the contours into feet, making my surface elevations range from approx. 14.5 to 15.5 feet and thus throwing off the volume calculations but a factor of 12^3. Can anyone help me get this straigtened out? Is there a setting that I am missing or something to cause this to happen?
