Syntax

C#

public class ExportLayerInfo : IDisposable

The ExportLayerInfo type exposes the following members.

Constructors

	Name	Description
	ExportLayerInfo	Constructs a new ExportLayerInfo with default values.

Properties

	Name	Description
	CategoryType	The category type which this layer belongs to.
	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.)
	ColorNumber	The color number stored in value.
	CutColorNumber	The cut color number stored in value.
	CutLayerName	The cut layer name stored in value.
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity.
	LayerName	The layer name stored in value.

Methods

	Name	Description
	AddCutLayerModifier	Adds a cut layer modifier to the layer info.
	AddLayerModifier	Adds a project layer modifier to the layer info.
	ClearCutLayerModifiers	Clears all the cut layer modifiers stored in the layer info.
	ClearLayerModifiers	Clears all the project layer modifiers stored in the layer info.
	Dispose	Releases all resources used by the ExportLayerInfo
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	GetCutLayerModifiers	Gets all the cut layer modifiers from the layer info.
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetLayerModifiers	Gets all the project layer modifiers from the layer info.
	GetType	Gets the Type of the current instance. (Inherited from Object)
	RemoveCutLayerModifier	Removes a cut layer modifier from the layer info.
	RemoveLayerModifier	Removes a project layer modifier from the layer info.
	SetCutLayerModifiers	Sets a cut layer modifier array to the layer info.
	SetLayerModifiers	Sets a project layer modifier array to the layer info.
	ToString	Returns a string that represents the current object. (Inherited from Object)

Example

C#

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;
}
