ArcGIS Pro对Revit 数据有自己的一套分层方式。
在ArcGIS Pro中打开bim文件会发现都是按照相同的方式组织数据:
将rvt格式数据转换成SLPK格式后的数据结构(将slpk数据直接拖动到ArcGIS Pro中加载):
ArcGIS 生成的SLPK格式数据将数据分为两个图层组,概览层(OverView)和完整模型层(Full Model),在完整模型层会按照ArcGIS自己的组织方式组织数据,对于没有数据的层,在转换成slpk后并不存在。
将SLPK数据发布成服务后,组织方式和在ArcGIS Pro中看到的是一样的(查看元数据:rest/services/Hosted/服务名称/SceneServer)。

通过分析元数据,可以看出数据结构,分为预览层和完整层,完整层再按照ArcGIS BIM模型的数据组织方式进行组织。
- Overview (预览图层:"layerType": "3DObject","modelName": "Overview")
- Full Model(完整模型图层组:"layerType": "group","modelName": "FullModel")
- Structural(结构图层组:"layerType": "group","modelName": "Structural")
- StructuralFraming(结构框架:"layerType": "3DObject","modelName": "StructuralFraming")
- Architectural(架构图层组)
- Windows(窗户:"layerType": "3DObject","modelName": "Windows")
- Walls(墙壁:"layerType": "3DObject","modelName": "Windows")
- ...等等
- Structural(结构图层组:"layerType": "group","modelName": "Structural")
“FullModel”和“Overview”是BuildingSceneLayer的直接子层。在使用ArcGIS Maps SDK for JavaScript(原ArcGIS JS API)的BuildingSceneLayer加载bim服务时,如果您想在BuildingSceneLayer的子组中搜索,可以使用BuildingSceneLayer.allSublayers,它是子图层的平面数组。要识别子图层,最好使用BuildingSceneLayer.modelName,因为这是基于I3S 规范的标准名称,无法更改。
参考:https://pro.arcgis.com/en/pro-app/latest/help/data/revit/adding-revit-data-to-arcgis-pro.htm
ArcGIS Maps SDK for JavaScript加载bim服务数据,控制bim服务图层的显示和隐藏代码示例:
buildingLayer.when(() => { // Iterate through the flat array of sublayers and extract the ones // that should be excluded from the slice widget buildingLayer.allSublayers.forEach((layer) => { // modelName is standard accross all BuildingSceneLayer, // use it to identify a certain layer switch (layer.modelName) { // Because of performance reasons, the Full Model view is // by default set to false. In this scene the Full Model should be visible. case "FullModel": layer.visible = true; break; case "Overview": case "Rooms": layer.visible = false; break; // Extract the layers that should not be hidden by the slice widget case "Doors": doorsLayer = layer; excludedLayers.push(layer); break; default: layer.visible = true; } }); });
