Unable to set active work plane

Hi everyone,

I want to activate a work plane but I got error message "Model lines can not be drawn in current view", please help me to verify the below method to activate a work plane

        public static void SetActiveWorkPlane(UIDocument uiDoc)
        {
            Transaction transaction = new Transaction(uiDoc.Document, "WorkPlane");
            transaction.Start();

            Plane plane = Plane.CreateByNormalAndOrigin(uiDoc.Document.ActiveView.ViewDirection,
                                    uiDoc.Document.ActiveView.Origin);

            SketchPlane sp = SketchPlane.Create(uiDoc.Document, plane);

            uiDoc.Document.ActiveView.SketchPlane = sp;
            uiDoc.Document.ActiveView.ShowActiveWorkPlane();

            transaction.Commit();
        }

Thanks & Regards,

Cuong
