Hi, we use a 3D Scene in our Runtime application and part of this is to visualize big hemispheres on ground with a diameter of a few kilometers. We recognized a problem when moving on the map with mouse and scrollwheel. When you want to move through the surface of the hemisphere to the ground, it seems that you hang up on the surface. It lasts many wheel movements until the movement auf the map continues. It feels, like you stick on the surface of the hemisphere and have to fight very hard to continue moving. I made a video with a sphere symbol showing, what I mean (actually a problem occurs with the video service, I will upload it again later on): (view in My Videos) SimpleMarkerSceneSymbol simpleMarkerSceneSymbol = new SimpleMarkerSceneSymbol() { Style = SimpleMarkerSceneSymbolStyle.Sphere, Color = Color.FromArgb(50, 0, 255, 255), Height = 90000, Width = 90000, Depth = 90000, AnchorPosition = SceneSymbolAnchorPosition.Bottom };‍‍‍‍‍‍‍‍‍ It looks as if the movement is oriented to the surface of objects. In the case of hemispheres, however, this is not desired. Can I change this for certain objects? Kind regards, Max ... View more

Hi, I created a special Feature Collection with a table which contains a Date field. //Create a feature collection and store it in a feature collection layer var fields = new List<Field> {new Field(FieldType.Date, "Date", "Date", 20)}; var table = new FeatureCollectionTable(fields, GeometryType.Point, SpatialReferences.Wgs84); table.Renderer = new SimpleRenderer(new SimpleMarkerSymbol{Color = Color.Blue, Size = 5}); var collection = new FeatureCollection(new [] {table}); var collectionLayer = new FeatureCollectionLayer(collection){Id = "FeatureCollectionLayer" }; var feature = table.CreateFeature(); feature.Geometry = new MapPoint(11.6,48.1, SpatialReferences.Wgs84); feature.Attributes["Date"] = DefaultDate; await table.AddFeatureAsync(feature); Map.OperationalLayers.Add(collectionLayer);‍‍‍‍‍‍‍‍‍‍‍‍‍ Now: When I want to Query this feature layer, I am not able to get a result match for my search date: //Now load try to query on this layer with a where clause on the date field var layer = ((FeatureCollectionLayer)Map.OperationalLayers["FeatureCollectionLayer"]).Layers.First(); var result = await layer.FeatureTable.QueryFeaturesAsync(new QueryParameters() { WhereClause = $"Date = '{DefaultDate}'" }); layer.SelectFeatures(result);‍‍‍‍‍‍‍ The result is always empty, no selection was made. DefaultDate by the way is a static value: public DateTime DefaultDate { get; set; } = new DateTime(2019, 05, 08, 6, 0, 0);‍ In the end I used int32 instead of Date as the data type for the field and converted the date into an integer, so it finally worked.  So my questions are: Why does it not work with data type Date? What was wrong here? Why does data type Date needs a length when creating the field? What is it for? Is it used? I missed a data type boolean. Any reasons why it is missing? Kind regards Max ...
