First, open the 3D Models menu from the left-hand sidebar (shown below in red).
Then, select a 3D model from the list. The next click you make on the map will place the 3D model onto the map’s surface.
Note: It could take a few moments for the 3D model to load onto the map’s surface.
You can also upload your own 3D models into the Equator platform. Simply drag and drop a .GLTF file into the map!
