3 In the Contour Elevation Interval list, select the difference in elevation
between contour lines, for example, 10, 20, or 50.
4 Select the units (meters or feet) used to measure the elevation in your
surface.
AutoCAD Map 3D attempts to get this unit from the surface itself, but
you can change it.
5 In the Major Contour Every list, select the interval between major (bold)
contour lines.
For example, if you choose 5, every fifth contour line will be bolded.
6 To label the major contour lines with the elevations they represent, select
the Label The Elevation check box.
7 For Create Contour As, select the type of feature to use when creating
contour lines (polyline or polygon).
8 For Save Contours Into Filename, enter a name for the new SDF file that
will store your contour line features.
9 Click OK.
The new contour line features are added to your map. They are placed on a

an SDF file.
To edit the line styles and labels used for the contour lines
1 In Display Manager, click the contour layer and click Style in the toolstrip.
2 In the Style Editor, modify the line styles and labels, as you would for
other features. For more information, see
Editing Features (page 701).
To change other contour settings, such as elevation interval and units,
you must remove the contour layer and recreate it using the settings you
want.
To delete a layer of contour lines
