What does “feature has null Z values” when using Move tool of Editor in ArcMap mean?

Question

i am trying to move a polygon from a location to another location. when using the move tool (editor) in ArcGIS, I place the x and y values to where i will move the polygon. however, when pressing enter, a message stating that the feature has null z values appear. how do I solve this problem?

Answer 1

Seams that the feature you are trying to edit was defined with Z value (elevation), yet the polygon doesn't have any z value, hence null.
