I would like to know if is it possible to pass z-values stored in a field (double) to the field Shape in a Z-enabled Feature Class preferably using the Field Calculator. If yes, could you post the expression that it is needed? I am using ArcGIS Desktop 10.1.
I will try the UpdateCursors functionality. In my case I have a Z-enabled feature class (points) whose Z values are 0. This same table has a numeric field with the elevation values.
