Properties
Name Description
Public property CategoryType The category type which this layer belongs to.
Public property ColorName The color name stored in value. For IFC export, the naming is to match the "colornumber" setting -- really, this stores a string that generates the colorNumber (for formats that don't use the color but need a second entry.)
Public property ColorNumber The color number stored in value.
Public property CutColorNumber The cut color number stored in value.
Public property CutLayerName The cut layer name stored in value.
Public property IsValidObject Specifies whether the .NET object represents a valid Revit entity.
Public property LayerName The layer name stored in value.

Example 
public bool ExportDWGModifyLayerTable(Document document, View view)
{
    bool exported = false;
    IList<string> setupNames = BaseExportOptions.GetPredefinedSetupNames(document);
    if (setupNames.Count > 0)
    {
        // Get the export options for the first predefined setup
        DWGExportOptions dwgOptions = DWGExportOptions.GetPredefinedOptions(document, setupNames[0]);

        // Get the export layer table
        ExportLayerTable layerTable = dwgOptions.GetExportLayerTable();

        // Find the first mapping for the Ceilings category
        string category = "Ceilings";
        ExportLayerKey targetKey = layerTable.GetKeys().First<ExportLayerKey>(layerKey => layerKey.CategoryName == category);
        ExportLayerInfo targetInfo = layerTable[targetKey];

        // change the color name and cut color number for this mapping
        targetInfo.ColorName = "31";
        targetInfo.CutColorNumber = 31;

        // Set the change back to the map
        layerTable[targetKey] = targetInfo;

        // Set the modified table back to the options
        dwgOptions.SetExportLayerTable(layerTable);

        ICollection<ElementId> views = new List<ElementId>();
        views.Add(view.Id);

        exported = document.Export(Path.GetDirectoryName(document.PathName),
            Path.GetFileNameWithoutExtension(document.PathName), views, dwgOptions);
