Use this procedure to change the length of any elevation boundary connected to the elevation line. You can change the length of the elevation as a whole, or you can change the length of the sides of the elevation boundary individually.
You can change the length of the elevation boundary before or after you create a connected elevation. If you change the length after creating the elevation, you need to update the elevation to show the changes.
You can also define the depth of an elevation (its length) by changing the length of the sides of an elevation boundary on the Properties palette.

The entire elevation boundary length is updated.
Side 1 starts from the first point specified for the elevation line.
Side 2 starts from the endpoint of the elevation line.
