What about opening the model twice, in the first model we delete all design options sets and then, from the second model we copy all design option geometrical elements to the first model? Would that be equivalent to accepting the design options?
//PROVIDE A MODEL PATH
String path="c:\\myRevitModel.rvt"
//Open your model a first time
Document doc = commandData.Application.OpenAndActivateDocument(path).Document;
//OPEN THE MODEL TEMPORARILY FOR A SECOND TIME
Document doc_temp = commandData.Application.OpenAndActivateDocument(path).Document;
//FIND ALL GEOMETRICAL ELEMENTS FROM THE PRIMARY DESIGN OPTIONS IN THE TEMPORARY MODEL
FilteredElementCollector finalCollectorTemp = new FilteredElementCollector(doc_temp);
PrimaryDesignOptionMemberFilter filterTemp = new PrimaryDesignOptionMemberFilter(false);
finalCollectorTemp.WherePasses(filterTemp);
finalCollectorTemp.WhereElementIsNotElementType();
finalCollectorTemp.WhereElementIsViewIndependent();
List<ElementId> TempElementsIDsList = new List<ElementId>();
foreach (Element i in finalCollectorTemp)
{
if ((null != i.Category) && (null != i.get_Geometry(new Options())))
{
TempElementsIDsList.Add(i.Id);
}
}
//SELECTING ALL DESIGN OPTION SETS AND DESIGN OPTIONS
finalCollector = new FilteredElementCollector(doc);
finalCollector.OfCategory(BuiltInCategory.OST_DesignOptions);
finalCollector.UnionWith((new FilteredElementCollector(doc)).OfCategory(BuiltInCategory.OST_DesignOptionSets));
ICollection<ElementId> ElementIDs = finalCollector.ToElementIds();
//DELETING ALL DESIGN OPTION SETS AND DESIGN OPTIONS
using (Transaction tx = new Transaction(doc))
{
tx.Start("Deleting all design options sets and all design options");
XYZ translation = new XYZ();
doc.Delete(ElementIDs);
tx.Commit();
}
//COPYING THE DESIGN OPTION ELEMENTS TO THE MODEL
ICollection<ElementId> CopiedElementsIDs = null;
using (Transaction tx = new Transaction(doc))
{
tx.Start("Copying Elements from Temporary Model to Main Model");
CopyPasteOptions copy_paste_options = new CopyPasteOptions();
XYZ translation = new XYZ();
Transform transform = Transform.Identity;
CopiedElementsIDs = Autodesk.Revit.DB.ElementTransformUtils.CopyElements(
doc_temp,TempElementsIDsList,doc, transform, copy_paste_options);
tx.Commit();
}
//CLOSE THE TEMPORARY MODEL
doc_temp.Close(false);
