Get DesignOptions in DesignOptionSet via API? (R22)

[eric.isaac2KKE9]

Is there a way to determine which DesignOptions are in a given DesignOptionSet via the API in Revit 2022?

I'm able to get a list of the DesignOptions, and a list of the DesignOptionSets, but I don't know how to correlate them.

Hi @eric.isaac2KKE9 ,

Try using this below sample code

 //Filter Design Option Sets Present in the Project
FilteredElementCollector designOptionSetcollector = new FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_DesignOptionSets).WhereElementIsNotElementType();
            
ElementFilter eFilter = new ElementCategoryFilter(BuiltInCategory.OST_DesignOptions);
            
foreach(Element e in designOptionSetcollector)
  {
   string designOptionSet_Name=e.Name;

   //Get all Design Options present in each DesignOptionSet
    IList<ElementId> designOptionList = e.GetDependentElements(eFilter);
    foreach(ElementId eid in designOptionList)
      {
          string designOptionName=doc.GetElement(eid).Name;
      }

}
