Get the list of all sheets which contains views from active Revit file and exporting the dwg

can you please me with this

Hi! To get help here, it's better to try writing the code first and figure out what exactly is not working.

If I were you, I would start by selecting ViewSheet objects via FilteredElementCollector. Next, each ViewSheet instance has a GetAllPlacedViews method. Check if it returns any view objects. If so, then there are views on the sheet. Finally, you need to create a DWGExportOptions object. Configure its properties. And pass it to Export method of Revit document.

Generally speaking, that's all it takes.

Here are some basic Python and C# basic samples:

sheets_ids = [
    sheet.Id for sheet in FEC(doc).OfClass(DB.ViewSheet)
    if sheet.GetAllPlacedViews()
]

export_options = DB.DWGExportOptions()
export_options.FileVersion = DB.ACADVersion.R2013
export_options.HideScopeBox = True
export_options.HideReferencePlane = True
export_options.MergedViews = True

output_path = "D:\dwg"

doc.Export(
    output_path,
    'test_',
    List[DB.ElementId](sheets_ids),
    export_options
)

List<ElementId> sheetIds = new List<ElementId>();
FilteredElementCollector collector = new FilteredElementCollector(doc).OfClass(typeof(ViewSheet));
foreach (ViewSheet sheet in collector)
{
    if (sheet.GetAllPlacedViews().Count > 0)
    {
        sheetIds.Add(sheet.Id);
    }
}

DWGExportOptions exportOptions = new DWGExportOptions();
exportOptions.FileVersion = ACADVersion.R2013;
exportOptions.HideScopeBox = true;
exportOptions.HideReferencePlane = true;
exportOptions.MergedViews = true;

string outputPath = @"D:\dwg";

doc.Export(
    outputPath,
    "test_",
    new List<ElementId>(sheetIds),
    exportOptions
);
