Can't select elements in a linked model

DanielKP2Z9V — Tue, 02 Apr 2024 18:09:17 GMT

I'm trying to select all columns in a linked model. However this doesn't work. It correctly gets Ids of the column elements, but the final ` uiDoc.Selection.SetElementIds(columnIds);` doesn't select anything.

Any help would be really appreciated.

[Transaction(TransactionMode.Manual)] public class SelectLinkedColumns : IExternalCommand { public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements) { // Get the Revit application and document UIApplication uiApp = commandData.Application; UIDocument uiDoc = uiApp.ActiveUIDocument; Document doc = uiDoc.Document; try { // Prompt user to select a linked Revit model Reference linkedRef = uiDoc.Selection.PickObject(ObjectType.LinkedElement, "Select a linked Revit model"); Element linkedElement = doc.GetElement(linkedRef.LinkedElementId); RevitLinkInstance linkedInstance = linkedElement as RevitLinkInstance; Document linkedDoc = linkedInstance.GetLinkDocument(); // Select all columns in the linked model FilteredElementCollector collector = new FilteredElementCollector(linkedDoc); ICollection<ElementId> columnIds = collector.OfCategory(BuiltInCategory.OST_Columns) .WhereElementIsNotElementType() .ToElementIds(); // Select the columns uiDoc.Selection.SetElementIds(columnIds); TaskDialog.Show("Success", $"Selected {columnIds.Count} columns in the linked model."); } catch (Exception ex) { TaskDialog.Show("Error", ex.Message); return Result.Failed; } return Result.Succeeded; } }

HI @DanielKP2Z9V

Unfortunately, we aren't able to Highlight Linked Model Elements. This feature is not available in Revit API :(.

Highlight Linked Elements discussion threat

A small suggestion in your code

// Prompt user to select a linked Revit model // You can directly select Linked Model itself, don't need to select Linked Element Reference linkedRef = uiDoc.Selection.PickObject(ObjectType.Element, "Select a linked Revit model"); Element linkedModel = doc.GetElement(linkedRef); RevitLinkInstance linkedInstance = linkedModel as RevitLinkInstance; Document linkedDoc = linkedInstance.GetLinkDocument();

Hope this will helps 🙂

@scgq425 by select I mean to select them in the Revit UI - the same way the user selects objects in a linked model by pressing TAB and left mouse button

thanks @Mohamed_Arshad, do you know where users can vote up this feature to be added to Revit API?

HI @DanielKP2Z9V

Already a threat has been raised in Idea Station and it is also accepted by the Autodesk Team. But I don't why they are not implemented still 😞 You can post your vote in the below link with a comment. Let's see 🙂

Hope this will Help 🙂

Threats won't help us convince autodesk to implementing users' ideas 🙂 but thanks for sharing the link - I've upvoted it as well

By the way this is not a solution - I've accidentally pressed that button and there doesn't seem to be a way to uncheck it now
