Does anyone know how I can replace the Z values contained within a feature class with values from a field from the same feature class? I have a feature class layer of contour lines that is Z enabled, but the Z values are all 0. The feature class layer has a field called 'elev' that contains the actual elevation values. I am new to working with Z values, so not that knowledgeable on the subject and would appreciate suggestions. I can see how to edit the Z values, but not understanding where they are stored. I am trying to avoid having to type in a bazilllion values manually.
