DWG export issue: Title Blocks do not get exported

[Anonymous]

I'm using the following code to export the sheets to dwg:

public void ExportToDWG(Document doc,ViewSheet view, string viewName, string output_path) {
    DWGExportOptions options = new DWGExportOptions()
    options.Colors = ExportColorMode.IndexColors
    options.ExportOfSolids = SolidGeometry.Polymesh
    options.FileVersion = ACADVersion.R2013
    options.HatchPatternsFileName = @"C:\Program Files\Autodesk\Revit 2017\ACADInterop\acdbiso.pat"
    options.HideScopeBox = true
    options.HideUnreferenceViewTags = true
    options.HideReferencePlane = true
    options.LayerMapping = "AIA"
    options.LineScaling = LineScaling.PaperSpace
    options.LinetypesFileName = @"C:\Program Files\Autodesk\Revit 2017\ACADInterop\acdbiso.lin"
    options.PropOverrides = PropOverrideMode.ByEntity
    options.TextTreatment = TextTreatment.Exact
    options.MergedViews = true
	
    ICollection<ElementId> views_collection = new List<ElementId>();
    views_collection.Add(view.Id);

    doc.Export(output_path, viewName, views_collection, options)
}
	

But when exporting the sheets, everything except Title Blocks gets exported:

Hi @Anonymous,

I tried to ExportDwg with no problems at all(see pictures below).

Would you like to share your example file for us to try?
