I want to create a polyline using a Button, not a Tool (see why below ). I use the following code:     protected override async void OnClick() { try { var spatialRef = GeometryFunctions.CreateLV95SpatialReference(); // Get mouse coordinates System.Drawing.Point screenPoint = Cursor.Position; System.Windows.Point winPoint = new System.Windows.Point(screenPoint.X, screenPoint.Y); var cursorPoint = await QueuedTask.Run(() => { return MapView.Active.ScreenToMap(winPoint); }); // Get current sketch Polyline existingWbl = await MapView.Active.GetCurrentSketchAsync() as Polyline; // Add point to current sketch var newWbl = AddPointToPolyline(existingWbl, cursorPoint, spatialRef); await MapView.Active.SetCurrentSketchAsync(newWbl); } catch (Exception ex) { ProPopupMessage.Error(MiscUtils.GetMethodName(), ex.Message); } } private Polyline AddPointToPolyline(Polyline polyline, MapPoint newPoint, SpatialReference spatialRef) { PolylineBuilderEx polylineBuilder = new PolylineBuilderEx(spatialRef); polylineBuilder.HasZ = true; // Step through all points List<MapPoint> newPointList = new List<MapPoint>(); if (polyline != null) { foreach (var existingPoint in polyline.Points) { newPointList.Add(existingPoint); } } newPointList.Add(newPoint); // Add polyline part polylineBuilder.AddPart(newPointList); return polylineBuilder.ToGeometry(); }     This code works if there already exists a sketch. If I want to add the first point of the polyline, however, it doesn't show on the stereo map. In ArcObjects, this was possible! Why do I want to create a polyline using a button instead of a tool? I want to use a button on a 3D mouse (https://pro.arcgis.com/en/pro-app/latest/help/analysis/image-analyst/set-up-the-stereo-mapping-stealth-3d-mouse.htm) ... View more
