Generate Contour dialog box

Use this dialog box to specify the settings for new contour lines for a raster-based surface.

To create contour lines

In Display Manager, right-click a surface layer, and select Create Contour Layer

NoteThis functionality applies only to raster-based surface data brought into AutoCAD Map 3D using Data Connect.

The Contour dialog box has the following options:

New Contour Layer Name

Enter the name for the new Display Manager layer that will contain the contour lines.

Contour Elevation Interval

Select the difference in elevation between contour lines, for example, 10, 20, or 50.


Select the units (meters or feet) used to measure the elevation in your surface. AutoCAD Map 3D attempts to get this data from the surface itself, but you can change it.

Major Contour Every

Select the difference in elevation between major (bold) contour lines. For example, if you select 5, every fifth contour line will be bolded.

Label the Elevation

Label the contour lines with the elevations they represent.

Create Contours As

Select the type of feature to use when creating contour lines (polyline or polygon).

Save Contours Into Filename

Enter a name for the new SDF file that will store your contour line features.
