Copies of cesium model

I have model in gltf-format: twr.gltf
When I do this:

viewer.entities.add({
  position: Cesium.Cartesian3.fromDegrees(72.1, 60.4),
  model:{
    uri: "/psi2/share/models/twr/twr.gltf"
  }
});

object appears on the map. When after I do this:

viewer.entities.add({
  position: Cesium.Cartesian3.fromDegrees(72.2, 60.5),
  model:{
    uri: "/psi2/share/models/twr/twr.gltf"
  }
});

new object doesn't appear on map. How could I "copy" model?

Hi there,

That code should work. Maybe 0.1 degrees of latitude is a much greater distance than you expect? Try a closer value.

Thanks,
