        Use the Contours page of the <link

        Options dialog box</link> to control how <link

    <para>
        Most GIS formats allow attributes to be associated with objects.
        When exporting contours in one of these formats, the contours'
        levels are associated with the contours as attributes.
    </para>
    <para>
        The DXF format does not support attributes. However, it does support
        named layers. If you check this box, NMPlot will export each contour
        in a separate layer. The name of each of these layers is created
        by taking the <link
        target='#NMPlot_ContourLineStyleLayerName_id'>contour layer name</link>
        and appending the contour's level to it.

            Options dialog box</link> only if you are exporting to a GIS in
            AutoCAD DXF format.
