Export

Exporting to gbXML

There are two methods for exporting to the Green Building XML format. The one whose last parameter is MassGBXMLExportOptions is only available for projects containing one or more instances of Conceptual Mass families. The MassGBXMLExportOptions object to pass into this method can be constructed with just the ids of the mass zones to analyze in the exported gbXML, or with the mass zone ids and the ids of the masses to use as shading surfaces in the exported gbXML. Whe using masses, they must not have mass floors or mass zones so as not to end up with duplicate surface information in the gbXML output.

The GBXMLExportOptions object used for the other gbXML export option has no settings to specify. It uses all default settings. Note that this method does not generate the energy model. The main energy model must already be stored in the document before this export is invoked.

Exporting to IFC

Calling Document.Export() using the IFC option will either use the default Revit IFC export implementation or a custom IFC Export, if one has been registered with the current session of Revit. In either case, the IFCExportOptions class is used to set export options such as whether to export IFC standard quantities currently supported by Revit or to allow division of multi-level walls and columns by levels.

Exporting to Navisworks

The Export method for Navisworks requires a compatible Navisworks exporter add-in registered with the current Revit session. If there is no compatible exporter registered, the method will throw an exception. Use the OptionalFunctionalityUtils.IsNavisworksExporterAvailable() method to determine if a Navisworks exporter is registered.

The NavisworksExportOptions object can be used to set numerous export settings for exporting to Navisworks, such as whether to divide the file into levels and whether or not to export room geometry. Additionally, the NavisworksExportOptions.ExportScope property specifieds the export scope. The default is Model. Other options include View and SelectedElements. When set to View, the NavisworksExportOptions . ViewId property should be set accordingly. This property is only used when the export scope is set to View. When set to SelectedElements, the NavisworksExportOptions . SetSelectedElementIds() method should be called with the ids of the elements to be exported.

Exporting to DWF and DWFX

Both DWF and DWFX files can be exported using the corresponding Document.Export() overloads. Both methods have a ViewSet parameter that represents the views to be exported. All the views in the ViewSet must be printable in order for the export to succeed. This can be checked using the View.CanBePrinted property of each view. The last parameter is either DWFExportOptions or DWFXExportOptions. DWFXExportOptions is derived from DWFExportOptions and has all the same export settings. Options include whether or not to export the crop box, the image quality whether or not to export textures to 3D DWF files, and the paper format.

public bool ExportViewToDWF(Document document, View view, string pathname)
{
    DWFExportOptions dwfOptions = new DWFExportOptions();
    // export with crop box and area and room geometry
    dwfOptions.CropBoxVisible = true;
    dwfOptions.ExportingAreas = true;
    dwfOptions.ExportTexture = false;
    ViewSet views = new ViewSet();
    views.Insert(view);
    return (document.Export(Path.GetDirectoryName(pathname),
        Path.GetFileNameWithoutExtension(pathname), views, dwfOptions));
}

public bool ExportDGN(Document document, View view)
{
    bool exported = false;
    // Get predefined setups and export the first one
    IList setupNames = BaseExportOptions.GetPredefinedSetupNames(document);
    if (setupNames.Count > 0)
    {
        // Get predefined options for first predefined setup
        DGNExportOptions dgnOptions = DGNExportOptions.GetPredefinedOptions(document, setupNames[0]);

        // export the active view if it is printable
        if (document.ActiveView.CanBePrinted == true)
        {
            ICollection views = new List();
            views.Add(view.Id);
            exported = document.Export(Path.GetDirectoryName(document.PathName),
                Path.GetFileNameWithoutExtension(document.PathName), views, dgnOptions);
        }
 }

    return exported;
}
