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

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);
    }

    return exported;
