1.相关概念

access token：bimface后端接口访问凭证，通过appkey和appsecret获取，其有效期为一周

view token：bimface模型临时访问凭证，其有效期为12小时

fileId：单个revit或其他模型上传后产生的唯一的ID

integrateId：多个模型集成在一起时产生的唯一的ID

componentId：构件ID，构件是模型操作的做小单元，单模型和集成模型的构件ID组成不同

elementId：图元，是原始模型文件的最小单元

2.数据来源

所有数据来自模型（revit、fbx、3ds、skp）文件上传

3.模型交互

模型载入成功后，默认会支持平移、缩放、旋转等操作，无需额外编写代码，以下是相对常用的模型交互的方法，被封装在Viewer3D对象中。

  • 模型交互高频方法
    • 显示 showComponentsById showComponentsByObjectData
    • 隐藏 showComponentsById showComponentsByObjectData
    • 着色 overrideComponentsColorById overrideComponentsColorByObjectData
    • 透明 transparentComponentsById transparentComponentsByObjectData
    • 隔离 isolateComponentsById isolateComponentsByObjectData
    • 视角 getCameraStatus setCameraStatus
    • 定位 zoomToSelectedComponents
    • 筛选

4.筛选维度

由于建筑模型构件数量较多，不可能一个一个操作构件，一方面开发复杂，容易出错，另方面也会影响整体性能。所以bimface提供了批量操作构件的方法。构件筛选的6个维度：分类、族、族类型、楼层、专业、系统类型，与下方对象属性一一对应。

{
  "categoryId": "-2000035",
  "family": "基本屋顶",
  "familyType": "常规ROOF - 400mm",
  "levelName": "ROOF",
  "specialty": "",
  "systemType":""
}

各个维度可以互相组合使用，筛选条件支持两种组合形式

  • 交集：既满足条件A，又满足条件B，A∩B；
  • 并集：满足条件A，或者满足条件B，A∪B。
// 交集
[
  {
    "categoryId": -2001340,
    "levelName": "F01"
  }
]
// 并集
[
  {
    "categoryId":-2001340,
    "levelName":"F01"
  },
  {
    "levelName":"F02"
  }
]

* 简单理解，筛选条件在一个对象内取交集部分，对象之间取并集。

条件如何获取

1.通过构件ID获取

2.通过构件树获取

3.通过接口获取

5.程序结构

程序结构框架如下，可根据使用的前端框架（VUE，REACT）的生命周期进行调整：

/**

import { WebUtils } from '../package/WebUtils.js'
import { ModelHelper } from '../package/ModelHelper.js'

var app, viewer, drawableContainer;

// 请求后端接口获取模型viewToken
webUtils.getViewtoken(2507720716406624, INTEGRATE_FILE).then((token) => {
    BimfaceLoaderConfig.viewToken = token;
    BimfaceSDKLoader.load(BimfaceLoaderConfig, onSDKLoadSucceeded, onSDKLoadFailed);
});

// SDK加载成功回调
function onSDKLoadSucceeded(viewMetaData) {
    
    // 指示当前viewToken是图纸还是模型
    if (viewMetaData.viewType == "3DView") {
        
        // 承载模型的DOM元素
        var view = document.getElementById('view');
