【问题描述】：

我正在尝试在包含多个模型的查看器中隔离一个 dbid 数组。但是问题有时会隔离模型 A 有时会隔离模型 B 有没有办法同时隔离两个模型？

function getExternalIds(model: any): any 
  return new Promise(function(resolve, reject) 
    model.getExternalIdMapping(resolve, reject);
  );


//---------------------------------------------
async function isolateAndColorObject(
  viewer: any,
  externalId ? : string[],
  color ? : any
) 
  const externalIds = await getExternalIds(viewer.model);

  let arr: any = [];
  externalId ? .forEach((id) => 
    const dbid = externalIds[id];

    arr.push(dbid);
  );


  for (const model of viewer.getAllModels())  //viewer.getVisibleModels()
    viewer.isolate(arr, model);
  





//calling the function:
isolateAndColorObject(viewer, [
  "5aa7c220-434e-47ec-966b-7aa35a5327a9-001c988b",
  "5cd83cb7-08c9-4bb2-bf3a-523af6622a4f-000e9567",
  "4845d7d6-c3ba-433c-9418-acbdb1ff7e5f-0011d9e2",
  "7e6d9dcb-b26f-4e71-9eb2-3169d28411da-001e3370",
]);

【参考方案1】：

更新：我已经修复了

function getExternalIds(
  model: Autodesk.Viewing.Model
): Promise< [key: string]: number > 
  return new Promise(function (resolve, reject) 
    model.getExternalIdMapping(resolve, reject);
  );


async function isolateAndColorObject(
  viewer: Autodesk.Viewing.GuiViewer3D,
  externalIds: string[]
) 
  let neededDbId: number[] = [];
  const allModels = viewer.getAllModels();

  if (allModels) 
    for await (const model of allModels) 
      const iExIds = await getExternalIds(model);
      if (iExIds) 
        externalIds.forEach((id: string) => 
          const dbid = iExIds[id];

          neededDbId.push(dbid);
        );
      
      viewer.isolate(neededDbId, model);
