This command will freeze a layer of contour lines and copy a specified interval to another layer. This allows the user to change the color or width of a certain interval.
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 AutoCAD
selection methods.
Select objects: press Enter Enter ends the
selection process. 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 copy
contours on
elevations 100, 110, 120, 130, 140 and 150 to the layer NCTR and freeze
the remaining lines on layer CTR.
