The grading base drawing is set up to display an elevation precision of 2 decimal places. On screen it is also displayed as 2. However when each individual grading plan that xreferences the grading base is opened, the elevation precision appears as 3. The settings in all drawings is confirmed to be 2 decimal places. Also when a drawing appears to display two decimal places for its elevations it plots out as 3 decimal places. This has been a reoccuring problem and most obvious solutions have been exercised. I am still in search of a solution.
