Hi, To convert a vertex to a control point, you have to simply change the ID of the vertex from 0 to 1. Control points have a vertex of 1. So you can iterate through the vertices to find the 4th and 7th vertices. In the following code snippet, I am changing two vertices in a selected polyline feature to be Control points. I iterate through the points in the selected line. Each point is converted into a MapPoint and gets added to a list. Points 6 and 7 are added as Control points. Notice the if statement on 20. These points are made "ID.Aware" and the IDs are set to be 1. Check out this page for more info: https://pro.arcgis.com/en/pro-app/latest/sdk/api-reference/topic27355.html I create a new polyline using the point collection. Then I use an edit operation to modify the selected line with the new line I just made.     var lineLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault(); if (lineLayer == null) return; var changeVertexIDOperation = new EditOperation(); QueuedTask.Run( () => { var lineLayerCursor = lineLayer.GetSelection().Search(); var lineVertices = new List<MapPoint>(); long oid = -1; while (lineLayerCursor.MoveNext()) { var lineFeature = lineLayerCursor.Current as Feature; var line = lineFeature.GetShape() as Polyline; int vertexIndex = 1; oid = lineFeature.GetObjectID(); foreach ( var point in line.Points ) { MapPointBuilderEx mapPointBuilderEx = new MapPointBuilderEx(point); //I am changing the vertex 6 and 7 to control points if (vertexIndex == 6 || vertexIndex == 7) { mapPointBuilderEx.HasID = true; mapPointBuilderEx.ID = 1; } lineVertices.Add(mapPointBuilderEx.ToGeometry() as MapPoint); vertexIndex++; } } var newLine = PolylineBuilderEx.CreatePolyline(lineVertices); changeVertexIDOperation.Modify(lineLayer, oid, newLine); changeVertexIDOperation.Execute(); });         ...

Hi, Here is a code snippet that sets a FeatureLayer to be uneditable.   QueuedTask.Run(() => { var cimFeatureLayer = layer.GetDefinition() as CIMFeatureLayer; var featureTable = cimFeatureLayer.FeatureTable; featureTable.Editable = false; cimFeatureLayer.FeatureTable = featureTable; layer.SetDefinition(cimFeatureLayer); }); ...

Hi,   Are you looking to add a new class break to a Unique Value renderer? If so, here is a code snippet: var layer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault(); if (layer == null) return; QueuedTask.Run( () => { var uvr = layer.GetRenderer() as CIMUniqueValueRenderer; if (uvr == null) return; var cimUniqueValueGroup = uvr.Groups[0] as CIMUniqueValueGroup; var classes = cimUniqueValueGroup.Classes; var cimUniqueValueClass = new CIMUniqueValueClass(); cimUniqueValueClass.Label = "New Value"; var lineSymbol = SymbolFactory.Instance.ConstructLineSymbol(ColorFactory.Instance.RedRGB, 2.0, SimpleLineStyle.Solid) ; lineSymbol.UseRealWorldSymbolSizes = false; cimUniqueValueClass.Symbol = lineSymbol.MakeSymbolReference(); #region New value to the class var cimUniqueValues = new List<CIMUniqueValue>(); var cimUniqueValue = new CIMUniqueValue() { FieldValues = new string[] { "New Value" } }; cimUniqueValues.Add(cimUniqueValue); #endregion cimUniqueValueClass.Values = cimUniqueValues.ToArray(); cimUniqueValueClass.Visible = true; var classesList = classes.ToList(); classesList.Add(cimUniqueValueClass); cimUniqueValueGroup.Classes = classesList.ToArray(); uvr.Groups[0] = cimUniqueValueGroup; layer.SetRenderer(uvr); });   Regarding your second question, if you are looking to add a new Symbol layer to an existing symbol, this is the code snippet:   var layer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault( s => s.ShapeType == esriGeometryType.esriGeometryPolyline); QueuedTask.Run( () => { var simpleRenderer = layer.GetRenderer() as CIMSimpleRenderer; var lineSymbol = simpleRenderer.Symbol.Symbol as CIMLineSymbol; if (lineSymbol == null) return; var layers = lineSymbol.SymbolLayers; var solidStroke = SymbolFactory.Instance.ConstructStroke(ColorFactory.Instance.RedRGB, 2.0, SimpleLineStyle.Solid); var offSetEffect = new CIMGeometricEffectOffset() { Method = GeometricEffectOffsetMethod.Rounded, Offset = 3, Option = GeometricEffectOffsetOption.Fast }; solidStroke.Effects = new CIMGeometricEffect[] { offSetEffect }; var layersList = layers.ToList(); layersList.Add(solidStroke); lineSymbol.SymbolLayers = layersList.ToArray(); simpleRenderer.Symbol = lineSymbol.MakeSymbolReference(); layer.SetRenderer(simpleRenderer); });   ...

Hi Tim, This is now fixed in ArcGIS Pro 3.3. Thanks for reporting this one. Uma ... View more

You can create a Dynamic Text element to write out the Map Frame's scale.    var layout = LayoutView.Active.Layout; if (layout == null) return; //Construct the dynamic text string. //You can create the dynamic text in the UI to get a hint as to how to compose the string in code. String title = @"Scale: <dyn type=""mapFrame"" name=""Map Frame"" property=""scale"" preStr=""1:""/>"; Coordinate2D llTitle = new Coordinate2D(6, 2.5); await QueuedTask.Run( () => { TextElement titleGraphics = ElementFactory.Instance.CreateTextGraphicElement( layout, TextType.RectangleParagraph, llTitle.ToMapPoint(), null, title) as TextElement; }); ...
