Hi Wilson,

Thanks for the reply. I am not able to set one design option as a primary design option because the property IsPrimary which was readonly. Is there any some other ways available to solve this?

Thanks and Regards,

He pointed you to a link that states that this functionality is NOT exposed in Revit API. That's your answer right there.

Here is a Q & A on this from the Revit API Panel @ AU Las Vegas 2017:

http://thebuildingcoder.typepad.com/blog/2017/11/revit-api-panel-au-las-vegas-2017.html

Q: Have a requirement to accept design options on the project.

A: Not exposed on the API, but just accept design option is easier, but needs to be on Revit Ideas.

Please check for a wish list item for the desired functionality in the Revit Idea Station and vote for it, if found; submit a new one, if not.

Here is a very tricky workaround suggestion, if you are willing to hack:

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);

@Anonymous, @jeremytammik

For those who are interested about Design Options, since Accepting Design Options is not yet possible by the Revit API, I am sharing a workaround which is deleting all non-Primary Design Options. I hope this is useful for others.

public void DeletingAllNonPrimaryDesignOptions(Document doc) { //Selecting All Design Options FilteredElementCollector collector = new FilteredElementCollector(doc); collector.OfCategory(BuiltInCategory.OST_DesignOptions); //Selecting All non-Primary Design Options List<ElementId> DesignOptionsNotPrimaryIDs = new List<ElementId>(); foreach (Element i in collector) { Autodesk.Revit.DB.DesignOption ii = i as Autodesk.Revit.DB.DesignOption; if (ii != null) { if (ii.IsPrimary != true) DesignOptionsNotPrimaryIDs.Add(ii.Id); } } //Deleting All non-Primary Design Options using (Transaction tx = new Transaction(doc)) { tx.Start("Deleting all non-primary design options") doc.Delete(DesignOptionsNotPrimaryIDs); tx.Commit(); } }
