You can edit either grading criteria or the elevations of the footprint or daylight line using edit commands on the Grading menu or the Grading Creation Tools.
Use the Grading Editor (Panorama) to edit unlocked criteria values for a grading object, the Grading Elevation Editor (Panorama) for feature lines and parcel lines, and additional commands for specific editing operations. You can also use grips to edit grading.
