Autodesk Forge Viewer : viewer.setThemingColor是否适用于转换后的DWG文件？

// 初始化 Autodesk Forge Viewer
const viewer = new Autodesk.Viewing.Private.GuiViewer3D(container);
const options = {
  env: 'AutodeskProduction',
  accessToken: 'your-access-token',
};
Autodesk.Viewing.Initializer(options, () => {
  viewer.start();
  loadModel();
});

// 加载 DWG 文件
async function loadModel() {
  const documentId = 'urn:your-model-urn';
  const viewables = await Autodesk.Viewing.Document.load(documentId);
  const viewable = viewables[0];
  const model = await viewable.load();
  viewer.setModel(model);
  viewer.autocam.setHomeViewFromModel();
}

// 设置主题颜色
function setThemingColor(dbId, color) {
  const material = new THREE.MeshPhongMaterial({ color: new THREE.Color(color) });
  viewer.impl.createOverlayScene('themingOverlay', material);
  viewer.impl.addOverlay('themingOverlay', dbId);
}

// 示例：为 DBID 为 1 的对象设置主题颜色
setThemingColor(1, 0xff0000); // 红色
