Revit 可以导出多种其他文件格式，比如：DWG,DWF,IFC,NWC等等，主要通过API:doc.Export()方法.

实例代码：

 public class ExportToOtherCommand : IExternalCommand    {        public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)        {            UIApplication uiapp = commandData.Application;            UIDocument uidoc = uiapp.ActiveUIDocument;            Document doc = uidoc.Document;            string projectName = Path.GetFileNameWithoutExtension(doc.PathName);            string viewName = doc.ActiveView.Name;            ////导出Dwf            //using (Transaction trans = new Transaction(doc, "Export to Dwf file"))            //{            //    trans.Start();            //    ExportToDWF(doc, $"D:\\Shared\\{projectName}_{viewName}.dwf");            //    trans.Commit();            //}            ////导出Nwc            //ExportToNwc(doc, $"D:\\Shared\\{projectName}_{viewName}.nwc");            ExportToDwg(doc, $"D:\\Shared\\{projectName}_{viewName}.dwg",false);            return Result.Succeeded;        }        /// 
        /// 导出Nwc文件,不需要开启事务        /// 
        ///         ///         public void ExportToNwc(Document document, string pathFullName)        {            NavisworksExportOptions nweOptions = new NavisworksExportOptions();            nweOptions.ExportScope = NavisworksExportScope.Model;            nweOptions.ViewId = document.ActiveView.Id;            //导出是否包括链接模型            nweOptions.ExportLinks = true;            //判断是否安装了Navisworks            bool isExporterAvailable = OptionalFunctionalityUtils.IsNavisworksExporterAvailable();            if (isExporterAvailable)            {                string folder = Path.GetDirectoryName(pathFullName);                string name = Path.GetFileNameWithoutExtension(pathFullName);                document.Export(folder, name, nweOptions);            }            else            {                TaskDialog.Show("tip", "导出失败！没有安装Navisworks");            }        }        /// 
        /// 导出dwf , 导出需要开启事务        /// 
        ///         ///         ///         public void ExportToDWF(Document document, string pathFullName, bool isActiveView = true)        {            FilteredElementCollector collector = new FilteredElementCollector(document);            collector.OfClass(typeof(View)).OfCategory(BuiltInCategory.OST_Views);            DWFExportOptions dwfOptions = new DWFExportOptions            {                CropBoxVisible = true,                ExportingAreas = true,                ExportTexture = false            };            ViewSet views = new ViewSet();            if (isActiveView)            {                views.Insert(document.ActiveView);            }            else            {                //多个视图                foreach (View view in collector.ToElements())                {                    if (view.CanBePrinted)                    {                        views.Insert(view);                    }                }            }            string folder = Path.GetDirectoryName(pathFullName);            string name = Path.GetFileNameWithoutExtension(pathFullName);            document.Export(folder,name, views, dwfOptions);        }        public void ExportToDwg(Document document, string pathFullName, bool isActiveView = true)        {            FilteredElementCollector collector = new FilteredElementCollector(document);            collector.OfClass(typeof(View)).OfCategory(BuiltInCategory.OST_Views);            DWGExportOptions dwgOptions = new DWGExportOptions            {                FileVersion = ACADVersion.R2010,            };            string folder = Path.GetDirectoryName(pathFullName);            string name = Path.GetFileNameWithoutExtension(pathFullName);            List viewIds = new List();            if (isActiveView)            {                viewIds.Add(document.ActiveView.Id);            }            else            {                //多个视图                foreach (View view in collector.ToElements())                {                    if (view.CanBePrinted)                    {                        viewIds.Add(view.Id);                    }                }            }            document.Export(folder, name, viewIds, dwgOptions);        }    }
