Hello, everyone.

I have a question, how can I get selected Polyline on Selection event.

My scratch code is following. But this is wrong, Please someone help me. Thank you.

public static void SubscribeToDoc(AcadDocument doc) { //doc.CommandEnded += new CommandEventHandler(doc_CommandEnded); var ed = doc.Editor; ed.SelectionAdded += Obj_Selected; } static void Obj_Selected(object sender, SelectionAddedEventArgs e) { var ids = e.AddedObjects.GetObjectIds(); var doc = Application.DocumentManager.MdiActiveDocument; var db = doc.Database; var ed = doc.Editor; TypedValue[] typedValueArray = new TypedValue[1]; typedValueArray.SetValue(new TypedValue((int)DxfCode.Start, "POLYLINE,LWPOLYLINE"), 0); var selectionFilter = new SelectionFilter(typedValueArray); var promptSelectionResult = ed.GetSelection(selectionFilter); var selectionSet = promptSelectionResult.Value; using (Transaction tr = db.TransactionManager.StartTransaction()) { foreach (SelectedObject obj in selectionSet) { Polyline poly = tr.GetObject(obj.ObjectId, OpenMode.ForRead, false) as Polyline; curPline = poly; } tr.Commit(); } }

Hi,

I guess you need to use the ImpliedSelectionChanged event. You find this EventHandler within the document object.

The Document.Editor.SelectImplied() returns the current selection.
