Is it possible to export some scene objects in .dxf files? If not possible what types of files can we export the scene?
Hello and welcome!
If you want to export a static scene, with just materials and geometries, the only format at the moment is .gltf.
Here is an example scene, which shows how to use the sop/exporter node. I could also add any of the other exporters supported by threejs if needed.
But I generally recommend to load the whole scene via javascript, instead of just exporting a static gltf. This would allow to still have the scene interactive. There are multiple integrations making this easy already, and more to come.
So feel free to say more about what you want to achieve, I could give a more specific help.
