Hi, I am required to export TIN data into WRL format using ArcObjects .NET SDK. So far I managed to come up with the following routine, that seems fine - but the created WRL file is empty. My code is as follows: ESRI.ArcGIS.Analyst3D.Scene sc = new ESRI.ArcGIS.Analyst3D.Scene(); TinLayer tl = new TinLayer(); TinClass t = new ESRI.ArcGIS.Geodatabase.TinClass(); t.Init("C:\\Data\\3DModels\\MtCoolum\\sw_508000_7061000_1k_class_l10"); tl.Dataset = t; //some test printouts Console.WriteLine(tl.Dataset.DataEdgeCount); //reasonable result in console, hence TinLayer is created from Tin t object Console.WriteLine(t.TriangleCount); //reasonable result in console sc.AddLayer(tl); Console.WriteLine(sc.LayerCount); //layer count is 1 - so layer is added to Scene Console.WriteLine(sc.get_Layer(0).Visible); //layer is visible VRMLExporter vrmlExporter = new VRMLExporter(); vrmlExporter.ExportFileName = "C:\\Data\\test.wrl"; vrmlExporter.ExportScene(sc); Everything works fine, but the created test.wrl is an empty file. The t TinClass instance seems all good, values and parameters related to this instance are all seem correct upon checking. I could not find any further parameters I can configure on VRMLExporter instance. Any help will be appreciated. Tamas
