Autodesk forge js 查看器加载多个窗口位置不正确

Question

我们正在尝试加载两个模型。这两个模型是从一个大模型中拆分出来的。
但是，我们无法使用 autodesk js 查看器正确恢复它们的位置，但 autodesk acc 模型协调可以。

urns.map((m)=>{
      Autodesk.Viewing.Document.load(`urn:${m.urn}`, (doc) => {
        let viewables = doc.getRoot().getDefaultGeometry();
        let viewerConf = {
          keepCurrentModels: true,
        }

        this.viewer.loadDocumentNode(doc, viewables, viewerConf).then(() => console.log('multiple model loaded'));
      })
    })

谁能提供有用的信息吗？

我们尝试了文档中的方法（上面），但没有成功

import { initViewer } from "https://aps-codepen.autodesk.io/utils.js";

      const options = {
        //  preserveView: true,
        keepCurrentModels: true
      };
      if (xform) {
        options.placementTransform = xform;
      }
      if (offset) {
        options.globalOffset = offset;
      }
      viewer
        .loadDocumentNode(doc, viewable, options)
        .then(resolve)

const viewer = await initViewer(document.getElementById("viewer"), {
