分形三维高级功能4/9-测量

简述

fractal 3D支持若干种测量功能，包括壁厚、棱边长度、距离、半径、平面夹角、体积，表面积。

关闭测量功能

可直接使用代码控制关闭部分测量功能

监听测量事件

不同的测量类型会有不同的测量数据产生，具体测量数据在此处可以获得。

示例代码：

// 在 api 中添加了一个测量
instance.on('addMeasure', (data)=> {
   console.log(data)
});

// 在 api 中删除了一个测量
instance.on('removeMeasure', (data)=> {
    console.log(data)
})

// 一个测量被更新
instance.on('updateMeasure', (data)=> {
    console.log(data)
})

测量相关事件在> 此处可以获得。

获取测量所有数据

instance.getMeasureList()

测量值数据结构

壁厚

{
    "measuretype": "thickness",
    "point1": {
        "x": -233.33166687497376,
        "y": -27.820770107593724,

}

棱边长度

• point1, point2 为棱边端点
• point 为点击处（导引线引出点）

其中，edgeType 为:

• line，直线
• arc，圆弧
• curve，曲线
