Hi, guys. I have got the extent of the map view from its extent property. As I need to load the data async from the backend when the user drags the map, so every time after user drag and stops, I need to send an API to the backend, which takes the current map lat/long on the four corners of the screen to the params of the API. I find the extent of the Mapview property, but its format is different from the lat/long. Is there any way or API to get the suitable lat/long of the four corners of the screen on the map? Thank you. ... View more

Hey all, I'm now using ArcGIS to build a 3D map, I downloaded the gltl model from the web and injected it inside the project. Then I want to use this model as the symbol, I checked the API that in Mesh has the method called 'createFromGLTF', then I tried to load the gltl model into the mesh and then draw it on the map, but it doesn't work. Can you help me to check what's the problem? or how to use the mesh component? The document is not too clear about that. The model I used is here: Avro Lancaster - Download Free 3D model by helijah (@helijah) - Sketchfab  thanks.. Mesh.createFromGLTF(           new Point({             x: 58.226,             y: 28.271,           }),           '/scene.gltf',         ).then(mesh => {           let graphic = new Graphic({             geometry: mesh,             symbol: {               type: 'mesh-3d',               symbolLayers: [{ type: 'fill' }],             },           });           view.graphics.add(graphic);         }); ...
