【问题描述】：

我对使用 AggregatedView 的 Forge 浏览器有疑问。 如果我在查看器中加载 3 个模型，则在浏览器中显示标签“模型”3 次，而不是 revit 文件名（“1.rvt”、“2.rvt”和“3.rvt”），如附件中所述图片forge browser。 是否可以改变行为（使用某些选项）？ 我尝试使用“accessControlProperties”选项 (https://forge.autodesk.com/en/docs/viewer/v2/reference/javascript/document/#load-documentid-onsuccesscallback-onerrorcallback-accesscontrolproperties)，但没有任何变化。

TIA 桤木

    launchViewer( models.concat() );

【参考方案1】：

要分配modelNameOverride，我们需要利用getCustomLoadOptions。参见下面的代码 sn-p 示例：

const options3d = 
  viewerConfig: 
    disableBimWalkInfoIcon: true,
  ,
  getCustomLoadOptions: (bubble) => 
    const modelName = bubble.getDocument().getRoot().search( role: "viewable" )[0].data.name;
    console.log(modelName);

    let loadOptions =  modelNameOverride: modelName ;
    return loadOptions;
  
;

view.init( viewerDiv, options3d );
