Three.js scene export to dxf

[Azure-Phoenix]

Could you help me to use this library to export my three.js scene to dxf?

function exportSceneToSTL(scene) {
  const exporter = new STLExporter();
  return exporter.parse(scene, { binary: false }); // ASCII STL
}

async function convertSTLtoDXF(stlString) {
  let deserializedStl = stlDeserializer.deserialize(
    {
      output: "csg", //jscad
    },
    stlString
  );
  console.log("CSG data were got");
  console.log(dxfSerializer);
  let dxfStringArray = dxfSerializer.serialize(deserializedStl);
  console.log("DXF data were got");
  return dxfStringArray;
}

function downloadDXF(dxfString, filename = "scene.dxf") {
  const blob = new Blob([dxfString], { type: "application/dxf" });
  const link = document.createElement("a");
  link.href = URL.createObjectURL(blob);
  link.download = filename;
  link.click();
}

/**
 * Action Listeners
 */
// Export on spacebar press
window.addEventListener("keydown", async (event) => {
  if (event.code === "Space") {
    const stlString = exportSceneToSTL(scene);
    const dxfString = await convertSTLtoDXF(stlString);
    downloadDXF(dxfString);
  }
});

I tried this steps, but it returns Uncaught (in promise) Error: only JSCAD geometries can be serialized to DXF error...

(The code is inspired from this discussion)

Sounds like could be possible. Can you make scene with a simple cube, and paste ouput of console.log("CSG data were got",deserializedStl); here.

The error means that the input to dxfSerializer.serialize() did not contain any JSCAD geometries. So, double check the results of stlDeserializer.deserialize(), or exporter.parse(). You are probably close.
