Forge 查看器中聚合视图场景中的选择

Question

我正在尝试使用 getAggregateSelection(selection) 函数在多模型场景中 select 元素。此函数以前工作正常，但开始时出现以下错误：

"viewer3D.min.js:18 Uncaught TypeError: Cannot read properties of undefined (reading 'length') at viewer3D.min.js:18:1301021 at u.setSelection (viewer3D.min.js:18:1301094) at c.setAggregateSelection (viewer3D.min.js:18:1305012) at C.de.setAggregateSelection (viewer3D.min.js:18:638482) at <anonymous>:1:15"

getAggregateSelction 函数工作正常。

Answer 1

刚刚在我的一个示例中尝试了 setAggregateSelection，它似乎工作正常。您确定输入参数的格式正确吗？应该是：

viewer.setAggregateSelection([
  {
    model: someModelInstance,
    ids: [123, 456]
  },
  {
    model: anotherModelInstance,
    ids: [789]
  }
]);
