Editing Slope Coordinates
To edit the slope coordinates, select Edit Coordinates 
from the Slope menu. The Edit Boundary Coordinates dialog will open and you can edit slope coordinates in table format. Once you've edited the coordinates, select OK to apply the changes.
In the Edit Boundary Coordinates dialog, you have the following tools for editing the slope coordinates:
- Select all cells, or a section of cells (this is useful if you want to perform the same action on multiple cells at once).
- Cut selected cells.
- Copy selected cells.
- Paste values into selected cells.
- Insert rows
- Delete rows.
- Append rows to table.
You can also import and export the table of coordinates. Note that only *.csv or *.txt files can be imported, and the export format is .txt.
If you select Set Global Statistics, you can set the X standard deviation and Y standard deviation for all vertices.
