在伪造查看器中加载图钉不尊重 viewerState

Question

我们正在使用 Forge 查看器中的“Autodesk.BIM360.Extension.PushPin”扩展来启用图钉。

当图钉添加到模型中时，我们将图钉数据序列化并将其存储在我们的数据库中。此类图钉的示例如下：

{
    "id": "12",
    "label": "12",
    "status": "quality_issues-not_approved",
    "position": {
        "x": 15.324803588519861,

            },
            "appearance": {
                "ghostHidden": true,
                "ambientShadow": true,
                "antiAliasing": true,
                "progressiveDisplay": true,
                "swapBlackAndWhite": false,
                "displayLines": true,
                "displayPoints": true
            }
        },
        "cutplanes": [],
        "globalOffset": {
            "x": -20.808594999999997,
            "y": 6.686511499999999,
            "z": 8.456207
        }
    },
    "objectData": {
        "guid": "6de5f80c-73da-30ae-b2d1-8a78f177c2a4",
        "urn": "dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6MDQyY2QwMmUtNzU0Yi00ZDY2LTgyYTMtNjBmYjFlOWVjMjcxL2U5ODAxZTA4LTUwZjQtNDc0ZS05ZWU4LTAxYWQ0ZGM0ODFiYl9WMV9Lb25nZXN0aWVuKzMwKy0rVGlsYnlnbmluZystK0clMjVDMyUyNUE2bGRlbmRlK2QuKzA1LjA2LnJ2dA",
        "viewableId": "aaff5911-e8b1-4ae2-b41c-4284d0703eb4-00150218",
        "viewName": "{3D}"
    }
}

然后我们稍后（当用户重新打开模型时）再次将图钉加载到模型中，如下所示：

pushPinExtension.loadItems([pushPinItem]);

结果是图钉添加到模型中的正确位置，但查看器状态不正确。在我们加载图钉时，图钉的查看器状态似乎设置为模型的查看器状态，而不是存储在图钉内的查看器状态。

这是预期的行为吗？ - 如果是这样，我该如何使用图钉中的查看器状态？

Answer 1

为什么在加载图钉后不显式加载单独存储在图钉中的查看器状态：

pushPinExtension.loadItems([pushPinItem]);
viewer.restoreState(pushPinItem.viewerState)

编辑：

尝试在单击项目时恢复查看器状态 - 使用以下命令订阅单击事件：

   viewer.restoreState(...)
   //...
})
