This command will move contours of a specified interval to
another layer. This allows the user to change the color or width of
a certain interval. This is useful if all the contours had been
generated on a single layer, and you wish to display the index
contours differently based on a new layer setting.
Layer name of existing contours <CTR>: press
Enter
Layer name for highlight contours <NCTR>: press
Enter
Select Contours to Highlight.
Select objects: Select contours using any standard selection
methods.
Select objects: press Enter to conclude selection.
The program then sorts and displays the High and Low interval of
the selected contours.
Contour increment to highlight: 10
Starting Highlight at elevation <98.0>: 100
Ending Highlight at elevation <152.0>: 150
Assuming we had drawn 1 foot intervals, the above example would
move the contours on elevations 100, 110, 120, 130, 140 and 150 to
the layer NCTR.
