Editing Grading objects
Because of the dynamic nature of grading objects, any edits to a feature line
that serves as a grading-object baseline will automatically trigger an update of
the grading object. This makes most grading-object editing fairly easy. In addi-
tion, there are two tools you can use to edit the criteria that were used to create
the grading object: Grading Editor and Edit Grading. The Grading Editor com-
mand opens Panorama, enabling you to edit the criteria in a table format. The
Edit Grading command is a command-line interface.
