求出测量值

Question

我在网页上伪造了我创造的模式。程序的行为应该是:用户按下按钮，启动测量工具，然后得到测量。

然而，我很难得到测量过的距离，也找不到任何能帮助我上网的东西。

感谢你的帮助，

您可以使用以下函数获得所有度量的列表：

const measureExtension = viewer.getExtension('Autodesk.Measure');
var measureList = measureExtension.getMeasurementList();

这将为您提供一系列如下所示的度量：

[{
    "from": "Vertex",
    "to": "Vertex",
    "distance": "260.7 mm",
    "deltaX": "29.4 mm",
    "deltaY": "14.8 mm",
    "deltaZ": "258.7 mm",
    "angle": "0.0 °",
    "area": "NaN",
    "arc": "0.0 mm",
    "location": "X: 0.0 mm\nY: 0.0 mm\nZ: 0.0 mm",
    "text": "",
    "unitType": "mm",
    "precision": 1,
    "picks": [
        {
            "intersection": {
                "x": 35.7674868316803,
                "y": 35.74486039263916,
                "z": 28.212904609725967
            },
            "modelId": 1,
            "viewportIndex2d": null,
            "snapNode": 14
        },
        {
            "intersection": {
                "x": 6.363343438640598,
                "y": 50.51345608813477,
                "z": -230.43969448657225
            },
            "modelId": 1,
            "viewportIndex2d": null,
            "snapNode": 16
        }
    ],
    "type": "Distance"
}]

此外，如果您希望每次执行新的度量，您可以订阅MEASUREMENT_COMPLETED_EVENT。

viewer.addEventListener(Autodesk.Viewing.MeasureCommon.Events.MEASUREMENT_COMPLETED_EVENT, (event)=> {
   /* HERE YOUR CODE */
});
