In combination with open source CLI model conversion\ntools, it represents a low-cost, high-performance way to get your IFC models on the Web, that allows you the freedom to\nconvert and host your models on your own server or GitHub repository.\n\nTo view your models with this viewer:\n\n1. Fork the [xeokit-bim-viewer](https://github.com/xeokit/xeokit-bim-viewer) repository on GitHub.\n1. Convert your IFC STEP files\n using [open source CLI tools](https://www.notion.so/xeokit/Viewing-an-IFC-Model-with-xeokit-c373e48bc4094ff5b6e5c5700ff580ee)\n .\n3. Add your converted models to your fork's data directory.\n4. Serve your fork using [GitHub Pages](https://pages.github.com/).\n\nThen users can view your models in their browsers, with URLs like this:\n\n[````https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=OTCConferenceCenter&tab=storeys````](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=OTCConferenceCenter&tab=storeys)\n\nRead the documentation below to get started.\n\n--- \n\n* [Releases / Changelog](https://github.com/xeokit/xeokit-bim-viewer/releases)\n* [Source Code](https://github.com/xeokit/xeokit-bim-viewer)\n* [API Docs](https://xeokit.github.io/xeokit-bim-viewer/docs)\n* [xeokit SDK](http://xeokit.io)\n\n---\n\n# Contents\n\n- [Features](#features)\n- [Demos](#demos)\n- [License](#license)\n- [The Viewer Application](#the-viewer-application)\n- [Model Database](#model-database)\n- [Viewer Configurations](#viewer-configurations)\n * [Viewer States](#viewer-states)\n- [Deploying XKT V7 and Earlier](#deploying-xkt-v7-and-earlier)\n- [Support for Multi-Part (Split) Models](#support-for-multi-part--split--models)\n- [Split Model with Separate Metadata Files](#split-model-with-separate-metadata-files)\n- [Programming API](#programming-api)\n * [Creating a Viewer](#creating-a-viewer)\n * [Configuring the Viewer](#configuring-the-viewer)\n * [Querying Projects, Models and Objects](#querying-projects--models-and-objects)\n + [Getting Info on Available Projects](#getting-info-on-available-projects)\n + [Getting Info on a Project](#getting-info-on-a-project)\n + [Getting Info on an Object](#getting-info-on-an-object)\n * [Loading Projects and Models](#loading-projects-and-models)\n + [Loading a Project](#loading-a-project)\n + [Loading a Model](#loading-a-model)\n * [Controlling Viewer State](#controlling-viewer-state)\n * [Saving and Loading BCF Viewpoints](#saving-and-loading-bcf-viewpoints)\n- [Customizing Viewer Style](#customizing-viewer-style)\n * [Modal Busy Dialog](#modal-busy-dialog)\n * [Tooltips](#tooltips)\n * [Customizing Appearances of IFC Types](#customizing-appearances-of-ifc-types)\n * [Localizing a Viewer](#localizing-a-viewer)\n- [xeokit Components Used in the Viewer](#xeokit-components-used-in-the-viewer)\n- [Building the Viewer](#building-the-viewer)\n * [Installing from NPM](#installing-from-npm)\n * [Building the Binary](#building-the-binary)\n * [Building the Documentation](#building-the-documentation)\n\n---\n\n# Features\n\n* Uses [xeokit](https://xeokit.io) for efficient model loading and rendering.\n* Works in all major browsers, including mobile.\n* Can load models from the file system.\n* Loads multiple models.\n* Saves and loads BCF viewpoints.\n* 3D and 2D viewing modes.\n* Interactively X-ray, highlight, show, hide and section objects.\n* Tree views of structure, layers and storeys.\n* Full-precision geometry.\n* Point clouds.\n* Supports IFC2x3 and IFC4.\n* Customize viewer appearance with your own CSS.\n* Localization support.\n* JavaScript programming API for all viewer functions.\n\n# Demos\n\nClick the links below to run some demos.\n\n| Live Demo | Model Source |\n|---|---|\n| [Double-Precision Model](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=MAP) | [BIMData](https://bimdata.io) |\n| [Point Cloud](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=MAPPointCloud)| [BIMData](https://bimdata.io) |\n| [OTC Conference Center](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=OTCConferenceCenter&tab=storeys) | [Details](http://openifcmodel.cs.auckland.ac.nz/Model/Details/301) |\n| [Revit Sample Project](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=RevitSamples&tab=models) | [Details](https://knowledge.autodesk.com/support/revit-products/getting-started/caas/CloudHelp/cloudhelp/2020/ENU/Revit-GetStarted/files/GUID-61EF2F22-3A1F-4317-B925-1E85F138BE88-htm.html) |\n| [Holter Tower](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=HolterTower&tab=storeys)| [Details](http://openifcmodel.cs.auckland.ac.nz/Model/Details/316) |\n| [West Riverside Hospital](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=WestRiversideHospital&tab=models)| [Details](http://openifcmodel.cs.auckland.ac.nz/Model/Details/308) |\n| [Schependomlaan](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=Schependomlaan&tab=storeys)| [Details](https://github.com/openBIMstandards/DataSetSchependomlaan) |\n| [Schependomlaan Ground Floor](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=Schependomlaan_selectedStorey&tab=storeys)| [Details](https://github.com/openBIMstandards/DataSetSchependomlaan) |\n| [Duplex](https://xeokit.github.io/xeokit-bim-viewer/app/index.html?projectId=Duplex&tab=storeys)| [Details](http://openifcmodel.cs.auckland.ac.nz/Model/Details/274) |\n\n# License\n\nxeokit-bim-viewer is bundled within the [xeokit SDK](http://xeokit.io), which is licensed under the AGPL3.

We'll describe it from the root directory\ndownwards.\n\nWithin the root, we have a directory for each project, along with a manifest of the projects in ````index.json````.\n\nWithin a project directory, we have a directory for each model in the project, along with a manifest of the models\nin ````index.json````.\n\nWithin a model directory, we have the ````.XKT```` file which contains the model's geometry and metadata.\n\n````\n.app/data/projects\n │\n ├── index.json\n │\n ├── Duplex\n │ │\n │ ├── index.json\n │ │\n │ └── models\n │ └── design\n │ └── geometry.xkt\n │\n └── WestRiversideHospital\n │\n ├── index.json\n │\n └── models\n ├── architecture \n │ └── geometry.xkt\n ├── structure \n │ └── geometry.xkt\n └── electrical\n └── geometry.xkt \n````\n\nThe ````index.json```` at the root of ````./app/data/projects```` is shown below.\n\nWithin this file, the ````id```` of each project matches the name of that project's subdirectory.\n\n````json\n{\n \"projects\": [\n {\n \"id\": \"Duplex\",\n \"name\": \"Duplex\"\n },\n {\n \"id\": \"WestRiversideHospital\",\n \"name\": \"West Riverside Hospital\"\n }\n //..\n ]\n}\n````\n\nThe ````index.json```` for the \"WestRiversideHospital\" project is shown below.\n\nWithin this file, the ````id```` of each model matches the name of that model's subdirectory. Each model's ````name````\nis the human-readable name that's displayed in the viewers Models tab.\n\n````json\n{\n \"id\": \"WestRiversideHospital\",\n \"name\": \"West Riverside Hospital Project\",\n \"models\": [\n {\n \"id\": \"architectural\",\n \"name\": \"Hospital Architecture\"\n },\n {\n \"id\": \"structure\",\n \"name\": \"Hospital Structure\"\n },\n {\n \"id\": \"electrical\",\n \"name\": \"Hospital Electrical\",\n \"saoEnabled\": false\n }\n ],\n \"viewerConfigs\": {\n \"backgroundColor\": [\n 0.9,\n 0.9,\n 1.0\n ]\n },\n \"viewerContent\": {\n \"modelsLoaded\": [\n \"structure\",\n \"architectural\"\n ]\n },\n \"viewerState\": {\n \"tabOpen\": \"models\"\n }\n}\n````\n\nThe optional ````viewerConfigs```` section specifies configurations for the viewer to set on itself as it loads the\nproject. See the complete list of available viewer configurations in [Viewer Configurations](#viewer-configurations).\n\nThe optional ````viewerContent```` array specifies IDs of models that the viewer will load initially, right after it's\napplied the configurations.\n\nThe optional ````viewerState```` section specifies how the viewer should set up the initial state of its UI, right after\nits loaded the initial models. See the complete list of available viewer states in [Viewer States](#viewer-states).\n\nThe ````geometry.xkt```` file for each model is created from an IFC file using open source CLI tools.

Think of these as user preferences. These may be\nprovided to the viewer within project info files, as described in [Model Database](#model-database), or set\nprogrammatically on the viewer\nwith [````BIMViewer#setConfigs()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html#instance-method-setConfigs)\n, as described in [Configuring the Viewer](#configuring-the-viewer).\n\n| Property | Type | Range | Default Value | Description |\n|:-----------------------|:--------|:-----------------------|:----------------------|:---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| \"backgroundColor\" | Array | | ````[1.0,1.0,1.0]```` | Canvas background color | \n| \"cameraNear\" | Number | ````[0.01-0.1]```` | ````0.05```` | Distance to the near clipping plane |\n| \"cameraFar\" | Number | ````[1-100000000]```` | ````3000.0```` | Distance to the far clipping plane |\n| \"smartPivot\" | Boolean | | ````true```` | Enables a better pivot-orbiting experience when click-dragging on empty space in camera orbit mode. |\n| \"saoEnabled\" | Boolean | | ````true```` | Whether or not to enable Scalable Ambient Obscurance (SAO) |\n| \"saoBias\" | Number | ````[0.0...10.0]```` | ````0.5```` | SAO bias |\n| \"saoIntensity\" | Number | ````[0.0...200.0]```` | ````100.0```` | SAO intensity factor |\n| \"saoScale\" | Number | ````[0.0...1000.0]```` | ````500.0```` | SAO scale factor |\n| \"saoKernelRadius\" | Number | ````[0.0...200.0]```` | ````100.0```` | The maximum area that SAO takes into account when checking for possible occlusion |\n| \"saoBlur\" | Boolean | | ````true```` | Whether Guassian blur is enabled for SAO |\n| \"edgesEnabled\" | Boolean | | ````true```` | Whether or not to enhance edges on objects |\n| \"pbrEnabled\" | Boolean | | ````false```` | Whether or not to enable Physically Based rendering (PBR) |\n| \"viewFitFOV\" | Number | ````[10.0...70.0]```` | ````30```` | When fitting objects to view, this is the amount in degrees of how much they should fit the user's field of view |\n| \"viewFitDuration\" | Number | ````[0..5]```` | ````0.5```` | When fitting objects to view with an animated transition, this is the duration of the transition in seconds |\n| \"perspectiveFOV\" | Number | ````[10.0...70.0]```` | ````55```` | When in perspective projection, this is the field of view, in degrees, that the user sees |\n| \"objectColors\" | Object | | ````undefined```` | A map of custom attributes for various IFC types |\n| \"externalMetadata\" | Boolean | | ````false```` | Whether to load a metadata.json file with each geometry.xkt file |\n| \"xrayPickable\" | Boolean | | ````false```` | Whether we can interact with X-rayed objects using mouse/touch input |\n| \"selectedGlowThrough\" | Boolean | | ````true```` | Whether selected objects appear to \"glow through\" other objects |\n| \"highlightGlowThrough\" | Boolean | | ````true```` | Whether highlighted objects appear to \"glow through\" other objects |\n| \"dtxEnabled\" | Boolean | | ````false```` | Whether to enable xeokit's data texture-based (DTX) scene representation and rendering mode. This has a lower memory footprint than the standard vertex buffer object-based (VBO) mode, and loads fast, but may be slower on low-spec GPUs. |\n| \"showSpaces\" | Boolean | | ````false```` | Whether to enable the visibility of IfcSpace elements. When this is ````false````, then even though we can instruct BIMViewer to make IfcSpaces visible in the tree view or context menus, they will remain invisible. This config is also dynamically controlled by the \"Show IfcSpaces\" tool in the toolbar. |\n\n## Viewer States\n\nIn [Model Database](#model-database) we saw how a project can specify directives for how the viewer should set up the\ninitial state of its UI, right after the project has loaded. The table below lists the available directives. These can\nalso be set on the viewer\nusing [````BIMViewer#setViewerState()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html#instance-method-setViewerState)\n. So far, we have:\n\n| Property | Type | Range | Default Value | Description |\n|:----------------------|:------------------|:----------------------|:------------------|:----------------------------------|\n| \"focusObject\" | String | | | ID of object to focus on | \n| \"tabOpen\" | String | \"objects\", \"classes\" or \"storeys\" | | Which explorer tab to open | \n| \"expandObjectsTree\" | Number | [0..*] | 0 | How deep to expand the \"objects\" tree |\n| \"expandClassesTree\" | Number | [0..*] | 0 | How deep to expand the \"classes\" tree |\n| \"expandStoreysTree\" | Number | [0..*] | 0 | How deep to expand the \"storeys\" tree |\n| \"setCamera\" | { eye: Number[], look: Number[], up: Number[] } | | 0 | Camera position |\n\n# Deploying XKT V7 and Earlier\n\n> **This section describes how to deploy models that use older versions of XKT that don't combine geometry and metadata.\nFor those older versions,\n> we need a little extra plumbing to deploy an additional JSON metadata file for each model.**\n\nThe previous section described how to deploy models that used XKT V8 and later. The XKT V8+ format combines geometry and\nmetadata into the same XKT file, and was introduced in the\n[xeokit v1.9 release](https://www.notion.so/xeokit/What-s-New-in-xeokit-1-9-b7503ca7647e43e4b9c76e1505fa4484).\n\nXKT versions prior to V8 only contained geometry, and needed to be accompanied by a JSON file that contained the model's\nIFC metadata. In this section, we'll describe how to deploy models that use XKT versions prior to V8.\n\nLet's imagine that we want to deploy the Duplex and West Riverside Hospital projects, using XKT V7. For each model\nwithin our database, we'll deploy a ````geometry.xkt````, which is an XKT V7 file containing the model's geometry, and\na ````metadata.json ````, containing IFC metadata for the model.\n\nWe'll just assume that you've got those files already, and are not ready to convert their original IFC files into XKT\nV8+.\n\nHere's our database files again, this time with XKT V7 and accompanying metadata files:\n\n````\n.app/data/projects\n │\n ├── index.json\n │\n ├── Duplex\n │ │\n │ ├── index.json\n │ │\n │ └── models\n │ └── design\n │ ├── geometry.xkt\n │ └── metadata.json\n │\n └── WestRiversideHospital\n │\n ├── index.json\n │\n └── models\n ├── architecture \n │ ├── geometry.xkt\n │ └── metadata.json\n ├── structure \n │ ├── geometry.xkt\n │ └── metadata.json\n └── electrical\n ├── geometry.xkt \n └── metadata.json \n````\n\nTo make BIMViewer load both the ````geometry.xkt```` and ````metadata.json```` files for each model, we need to add a\nnew ````externalMetadata: true```` configuration to the ````viewerConfigs```` in the project's ````index.json```` file:\n\n````json\n{\n \"id\": \"WestRiversideHospital\",\n \"name\": \"West Riverside Hospital\",\n \"models\": [\n {\n \"id\": \"architectural\",\n \"name\": \"Hospital Architecture\"\n },\n {\n \"id\": \"structure\",\n \"name\": \"Hospital Structure\"\n },\n {\n \"id\": \"electrical\",\n \"name\": \"Hospital Electrical\",\n \"saoEnabled\": false\n }\n ],\n \"viewerConfigs\": {\n \"externalMetadata\": true, // <<------------ ADD THIS\n \"backgroundColor\": [\n 0.9,\n 0.9,\n 1.0\n ]\n },\n \"viewerContent\": {\n \"modelsLoaded\": [\n \"structure\",\n \"architectural\"\n ]\n },\n \"viewerState\": {\n \"tabOpen\": \"models\"\n }\n}\n````\n\n# Support for Multi-Part (Split) Models\n\nSince xeokit-bim-viewer 2.4, we can deploy models that are split into multiple XKT files (with optional external JSON\nmetadadata files).\n\nThe `ifc2gltf` tool from Creoox, which converts IFC files into glTF geometry and JSON metadata files, has the option to\nsplit its output into multiple pairs of glTF and JSON files, accompanied by a JSON manifest that lists the files.\n\nTo integrate with that option, the `convert2xkt` tool, which converts glTF geometry and JSON metadata files into XKT\nfiles, also has the option to batch-convert the glTF+JSON files in the manifest, in one invocation.\n\nWhen we use this option, convert2xkt will output a bunch of XKT files, along with a JSON manifest file that lists those\nXKT files.\n\nThis feature extends BIMViewer with the option to load models comprised of multiple XKT files, combining the XKT files into a single tree view for each model, and enabling the unloading of the model to unload all its XKT files in one shot. In other words, instead of having a separate model and tree view for each XKT, we can now group a bunch of XKT files together to behave as one model in BIMViewer.\n\nLearn more about the conversion of IFC models into multiple XKT files in [this tutorial](https://www.notion.so/xeokit/Importing-Huge-IFC-Models-as-Multiple-XKT-Files-165fc022e94742cf966ee50003572259).\n\nTo show how to deploy one of these multi-XKT models in BIMViewer, let's examine the Karhumaki project.\n\n---\n* [Load the Karhumaki Project in BIMViewer](https://xeokit.io/demo.html?projectId=Karhumaki)\n---\n\n````\n.app/data/projects\n │\n ├── index.json\n │\n └── Karhumaki\n │\n ├── index.json\n │\n └── models\n └── KarhumakiBridge \n ├── manifest.json \n ├── model.xkt \n ├── model_1.xkt\n ├── model_2.xkt\n ├── model_3.xkt\n ├── model_4.xkt\n ├── model_5.xkt\n ├── model_6.xkt\n ├── model_7.xkt\n ├── model_8.xkt\n └── model_9.xkt \n````\n\nThe `manifest.json` XKT manifest looks like this:\n\n````json\n{\n \"xktFiles\": [\n \"model.xkt\",\n \"model_1.xkt\",\n \"model_2.xkt\",\n \"model_3.xkt\",\n \"model_4.xkt\",\n \"model_5.xkt\",\n \"model_6.xkt\",\n \"model_7.xkt\",\n \"model_8.xkt\",\n \"model_9.xkt\"\n ]\n}\n````\n\nThe ````index.json```` for the \"Karhumaki\" project is shown below.\n\nWithin this file, as usual, the ````id```` of each model matches the name of that model's subdirectory. Each model's ````name```` is the human-readable name that's displayed in the viewers Models tab.\n\nTo indicate that the model is a multi-part model, with multiple XKTs, the model entry gets a ````manifest```` property containing the file name of our `manifest.json` file.\n\nIn `viewerContent`, we specify that our multipart model gets loaded immediately, as soon as the project is loaded.\n\n````json\n{\n \"id\": \"Karhumaki\",\n \"name\": \"Karhumaki\",\n \"models\": [\n {\n \"id\": \"Karhumaki-Bridge\",\n \"name\": \"Karhumaki Bridge\",\n \"manifest\": \"manifest.json\"\n }\n ],\n \"viewerConfigs\": {\n \"backgroundColor\": [\n 0.9,\n 0.9,\n 1.0\n ]\n },\n \"viewerContent\": {\n \"modelsLoaded\": [\n \"Karhumaki-Bridge\"\n ]\n },\n \"viewerState\": {\n \"tabOpen\": \"models\"\n }\n}\n````\n\n# Split Model with Separate Metadata Files\n\nIn recent versions of xeokit, we combine the geometry and metadata into the XKT files, for simplicity within the pipeline, as we've done in the example above.\n\nIn older versions of XKT, as mentioned above, we would have the metadata in separate JSON files, so that each XKT file would have the geometry, and would be accompanied by a JSON file containing its IFC metadata.\n\nBIMViewer, and the rest of the xeokit SDK, remains backwardly compatible with this XKT+JSON separation. The split-model loading feature also remains backwardly-compatible, as demonstrated in the \"WestRiversideHospital_Combined\" example project, described below.\n\n---\n* [Load the WestRiversideHospital_Combined Project in BIMViewer](https://xeokit.io/demo.html?projectId=WestRiversideHospital_Combined)\n---\n\nWe have our separated XKT and JSON metadata files in the `models` directory:\n\n````\n.app/data/projects\n │\n ├── index.json\n │\n └── WestRiversideHospital_Combined\n ├── index.json\n │\n └── models\n │\n └── WestRiversideHospital\n ├── architectural.json\n ├── architectural.xkt\n ├── electrical.json\n ├── electrical.xkt\n ├── fireAlarms.json\n ├── fireAlarms.xkt\n ├── manifest.json\n ├── mechanical.json\n ├── mechanical.xkt\n ├── plumbing.json\n ├── plumbing.xkt\n ├── sprinklers.json\n ├── sprinklers.xkt\n ├── structure.json\n └── structure.xkt\n````\n\nThe `manifest.json` XKT manifest looks as below. Notice the additional `metaModelFiles` property, which lists the JSON files that comprise the metamodel for the \"WestRiversideHospital\" model:\n\n````\n{\n \"xktFiles\": [\n \"architectural.xkt\",\n \"electrical.xkt\",\n \"fireAlarms.xkt\",\n \"mechanical.xkt\",\n \"plumbing.xkt\",\n \"sprinklers.xkt\",\n \"structure.xkt\"\n ],\n \"metaModelFiles\": [\n \"architectural.json\",\n \"electrical.json\",\n \"fireAlarms.json\",\n \"mechanical.json\",\n \"plumbing.json\",\n \"sprinklers.json\",\n \"structure.json\"\n ]\n}\n````\n\nFinally, the ````index.json```` for the \"WestRiversideHospital_Combined\" project is shown below.\n\nWithin this file, as before, the ````id```` of each model matches the name of that model's subdirectory, and Each model's ````name```` is the human-readable name that's displayed in the viewers Models tab.\n\nAs before, to indicate that the model is a multi-part model, with multiple XKTs, the model entry gets a ````manifest```` property containing the file name of our `manifest.json` file.\n\nIn `viewerContent`, we specify that our multipart model gets loaded immediately, as soon as the project is loaded.\n\n````json\n{\n \"id\": \"WestRiversideHospital_Combined\",\n \"name\": \"West Riverside Hospital\",\n \"models\": [\n {\n \"id\": \"WestRiversideHospital\",\n \"name\": \"West Riverside Hospital\",\n \"saoEnabled\": true,\n \"manifest\": \"manifest.json\"\n }\n ],\n \"viewerConfigs\": {\n \"backgroundColor\": [0.9, 0.9, 1.0],\n \"externalMetadata\": true\n },\n \"viewerContent\": {\n \"modelsLoaded\": [\n \"WestRiversideHospital\"\n ]\n },\n \"viewerState\": {\n \"viewCubeEnabled\": true,\n \"threeDEnabled\": true,\n \"tabOpen\": \"models\"\n }\n}\n````\n\n# Programming API\n\n> **This section goes deeper into the viewer, describing how to instantiate a viewer, and how to use its JavaScript\nprogramming API.**\n\nThe viewer is implemented by the\nJavaScript [````BIMViewer````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html)\nclass, which provides a complete set of methods to programmatically control it.\n\nUsing these methods, we can:\n\n* create and configure a viewer,\n* query what models are available,\n* load projects and models,\n* interact with the 3D view,\n* save and load BCF viewpoints,\n* control the various viewer tools, and\n* drive the state of the viewer's UI.\n\n## Creating a Viewer\n\nIn the example below, we'll create\na [````BIMViewer````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html), with\na [````Server````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/server/Server.js~Server.html) through which\nit will load projects and models from the file system.\n\nWe'll configure the ````Server```` to load that data from\nthe [````./app/data````](https://github.com/xeokit/xeokit-bim-viewer/tree/master/app/data) directory.\n\nWe'll also configure our ````BimViewer```` with DOM elements to hold the four parts of its UI, which are:\n\n1. the 3D canvas,\n2. the explorer panel containing the tree views,\n3. the toolbar,\n4. the NavCube, and\n4. the \"backdrop\" element, which covers everything in the UI to prevent interaction whenever the viewer is busy loading\n a model.\n\n````javascript\nconst server = new Server({\n dataDir: \"./data\"\n});\n\nconst myBIMViewer = new BIMViewer(server, {\n canvasElement: document.getElementById(\"myCanvas\"), // The 3D WebGL canvas\n explorerElement: document.getElementById(\"myExplorer\"), // Container for the explorer panel\n toolbarElement: document.getElementById(\"myToolbar\"), // Container for the toolbar\n navCubeCanvasElement: document.getElementById(\"myNavCubeCanvas\"), // Canvas for the NavCube\n busyModelBackdropElement: document.querySelector(\".xeokit-busy-modal-backdrop\") // Busy modal dialog backdrop element\n});\n````\n\nConfiguring the ````BIMViewer```` with separate places in the document to locate its parts allows us to integrate them\nmore flexibly into our web page.\n\nIn our [````app/index.html````](https://github.com/xeokit/xeokit-bim-viewer/blob/master/app/index.html) page, the HTML\nelements look like this:\n\n````html\n\n<div id=\"myViewer\" class=\"xeokit-busy-modal-backdrop\">\n <div id=\"myExplorer\" class=\"active\"></div>\n <div id=\"myContent\">\n <div id=\"myToolbar\"></div>\n <canvas id=\"myCanvas\"></canvas>\n </div>\n</div>\n<canvas id=\"myNavCubeCanvas\"></canvas>\n````\n\nSee [````app/css/style.css````](https://github.com/xeokit/xeokit-bim-viewer/blob/master/app/css/style.css) for how we've\nstyled these elements.\n\nAlso\nsee [````dist/xeokit-bim-viewer.css````](https://github.com/xeokit/xeokit-bim-viewer/blob/master/dist/xeokit-bim-viewer.css)\nfor the CSS styles that BIMViewer applies to the elements it creates internally.\n\n## Configuring the Viewer\n\nWith our viewer created, let's\nuse [````BIMViewer#setConfigs()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html#instance-method-setConfigs)\nto configure it.\n\nWe'll just set the canvas background color to white:\n\n````javascript\nmyBIMViewer.setConfigs({\n \"backgroundColor\": [1.0, 1.0, 1.0]\n});\n````\n\nSee [Viewer Configurations](#viewer-configurations) for the list of available configurations.\n\n## Querying Projects, Models and Objects\n\nWith our viewer created and configured, let's find out what content is available.\n\n### Getting Info on Available Projects\n\nLet's query what projects are available.\n\n````javascript\nmyBIMViewer.getProjectsInfo((projectsInfo) => {\n console.log(JSON.stringify(projectsInfo, null, \"\\t\"));\n});\n````\n\nInternally, the viewer will\ncall [````Server#getProjects()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/server/Server.js~Server.html#instance-method-getProjects)\nto get the projects info.\n\nAs described earlier in [Model Database](#model-database), the projects info is the JSON\nin [````./app/data/projects/index.json````](https://github.com/xeokit/xeokit-bim-viewer/tree/master/app/data/projects/index.json)\n. We'll just log that info to the console.\n\nThe projects info will look similar to:\n\n````json\n{\n \"projects\": [\n {\n \"id\": \"Duplex\",\n \"name\": \"Duplex\"\n },\n {\n \"id\": \"Schependomlaan\",\n \"name\": \"Schependomlaan\"\n },\n {\n \"id\": \"WestRiversideHospital\",\n \"name\": \"West Riverside Hospital\"\n }\n ]\n}\n````\n\n### Getting Info on a Project\n\nNow we know what projects are available, we'll get info on one of those projects.\n\n````javascript\nmyBIMViewer.getProjectInfo(\"WestRiversideHospital\", (projectInfo) => {\n console.log(JSON.stringify(projectInfo, null, \"\\t\"));\n});\n````\n\nInternally, the viewer will\ncall [````Server#getProject()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/server/Server.js~Server.html#instance-method-getProject)\nto get that project info. Like before, we'll just log it to the console.\n\nThe project info will be the contents\nof [````./app/data/projects/WestRiversideHospital/index.json````](https://github.com/xeokit/xeokit-bim-viewer/tree/master/app/data/projects/WestRiversideHospital/index.json)\n.\n\nThe project info will be similar to:\n\n````json\n{\n \"id\": \"WestRiversideHospital\",\n \"name\": \"West Riverside Hospital\",\n \"models\": [\n {\n \"id\": \"architectural\",\n \"name\": \"Hospital Architecture\"\n },\n {\n \"id\": \"structure\",\n \"name\": \"Hospital Structure\"\n },\n {\n \"id\": \"electrical\",\n \"name\": \"Hospital Electrical\",\n \"saoEnabled\": false\n }\n ],\n \"viewerConfigs\": {\n \"backgroundColor\": [\n 0.9,\n 0.9,\n 1.0\n ],\n \"saoEnabled\": true\n },\n \"viewerContent\": {\n \"modelsLoaded\": [\n \"structure\",\n \"architectural\"\n ]\n },\n \"viewerState\": {\n \"tabOpen\": \"models\"\n }\n}\n````\n\nIn this project info, we have:\n\n* **````id````** - ID of the project,\n* **````name````** - human-readable name of the project,\n* **````models````** - info on each model in this project,\n* **````viewerConfigs````** - configurations for the viewer to apply when loading the project,\n* **````viewerContent````** - which models the viewer should immediately load when loading the project, and\n* **````viewerState````** - how the viewer should set up its UI after loading the project.\n\nWhen we later load the project in section [Loading a Project](#loading_a_project), the viewer is going to pass\nthe ````viewerConfigs````\nto [````BIMViewer#setConfigs()````](https://xeokit.github.io/xeokit-sdk/docs/class/src/BIMViewer.js~BIMViewer.html#instance-method-setConfigs)\n, which we described earlier in [Configuring the Viewer](#configuring-the-viewer).\n\nIn the ````viewerConfigs```` we're enabling the viewer's Scalable Ambient Obscurance effect, which will create ambient\nshadows in the crevices of our models. This is an expensive effect for the viewer to render, so we've disabled it for\nthe \"electrical\" model, which contains many long, thin wire objects that don't show the SAO effect well.\n\n### Getting Info on an Object\n\nLet's attempt to get some info on an object within one of our project's models.\n\nWe say \"attempt\" because it's up to\nthe [````Server````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/server/Server.js~Server.html) to try to\nfind that info for us, which might not exist.\n\nInternally, the viewer will\ncall [````Server#getObjectInfo()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/server/Server.js~Server.html#instance-method-getObjectInfo)\n, which will attempt to load that object info from a file.\n\nIf you were to substitute ````Server```` with your own implementation, your implementation might get that info from a\ndata store, such as a relational database, populated with metadata for all the objects in your project's models, keyed\nto their IDs.\n\nWe'll go ahead and assume that our ````Server```` has info an an object.\n\n````javascript\nmyViewer.getObjectInfo(\"WestRiversideHospital\", \"architectural\", \"2HaS6zNOX8xOGjmaNi_r6b\",\n (objectInfo) => {\n console.log(JSON.stringify(objectInfo, null, \"\\t\"));\n },\n (errMsg) => {\n console.log(\"Oops! There was an error getting info for this object: \" + errMsg);\n });\n````\n\nIf the object does not exist in the specified project and model, the method will invoke its error callback.\n\nOur file system database does happen to have info for that object, stored\nin [````./app/data/projects/WestRiversideHospital/models/architectural/objects/2HaS6zNOX8xOGjmaNi_r6b.json````](https://github.com/xeokit/xeokit-bim-viewer/tree/master/app/data/projects/WestRiversideHospital/models/architectural/objects/2HaS6zNOX8xOGjmaNi_r6b.json)\n.\n\nSince our object info exists, we'll get a result similar to this:\n\n````json\n{\n \"id\": \"2HaS6zNOX8xOGjmaNi_r6b\",\n \"projectId\": \"WestRiversideHospital\",\n \"modelId\": \"architectural\",\n \"name\": \"Basic Wall:Exterior - Metal Panel on Mtl. Stud:187578\",\n \"type\": \"IfcWall\",\n \"parent\": \"2hExBg8jj4NRG6zzD0RZML\"\n}\n```` \n\n> By now, you've probably noticed that our file system database is structured to\n> support [RESTful](https://en.wikipedia.org/wiki/Representational_state_transfer) URIs, which\n> our [````Server````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/server/Server.js~Server.html) constructs\n> from the project, model and object IDs we supplied to the viewer's query methods.\n\n## Loading Projects and Models\n\nLet's now load some of the projects and models that we queried in the previous section.\n\n### Loading a Project\n\nLet's start by loading the project we just queried info on.\n\n````javascript\nmyBIMViewer.loadProject(\"WestRiversideHospital\",\n () => {\n console.log(\"Nice! The project loaded successfully.\");\n },\n (errMsg) => {\n console.log(\"Oops! There was an error loading this project: \" + errMsg);\n });\n````\n\nIf that succeeds, the viewer will now have two models loaded, ````\"architectural\"```` and ````\"structure\"````, since\nthose are specified in the project info's ````viewerContent````.\n\nThe viewer will also enable Scalable Ambient Obscurance, since that's specified by the ````saoEnabled```` property in\nthe ````viewerConfigs````. The viewer will also set various other configs on itself, as specified in that section.\n\nThe viewer will also open its \"Models\" tab, thanks to the ````tabOpen```` property in the project\ninfo's ````viewerState```` section.\n\nWe can confirm that the two models are loaded by querying the IDs of the models that are currently loaded in the viewer:\n\n````javascript\nconst modelIds = myBIMViewer.getModelLoadedIds();\n\nconsole.log(modelIds);\n````\n\nThe result would be:\n\n````json\n[\n \"architectural\",\n \"structure\"\n]\n````\n\n### Loading a Model\n\nWith our project loaded, let's load another of its models.\n\nWe could start by getting the IDs of all the models in our project, just to make sure the model is available:\n\n````javascript\nconst modelIds = myBIMViewer.getModelIds();\n\nconsole.log(modelIds);\n````\n\nThe result would be:\n\n````json\n[\n \"architectural\",\n \"structure\",\n \"electrical\"\n]\n````\n\nTo load the model:\n\n````javascript\nmyBIMViewer.loadModel(\"electrical\",\n () => {\n console.log(\"Nice! The model loaded successfully.\");\n },\n (errMsg) => {\n console.log(\"Oops! There was an error loading this model: \" + errMsg);\n });\n````\n\nIf we no longer need that model, we can unload it again:\n\n````javascript\nmyBIMViewer.unloadModel(\"electrical\");\n````\n\nWhen we no longer need the project, unload like so:\n\n````javascript\nmyBIMViewer.unloadProject();\n````\n\nNote that we can only load one project at a time.\n\n## Controlling Viewer State\n\n[````BIMViewer````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html) has various\nmethods with which we can programmatically control the state of its UI.\n\nLet's take a quick look at some of these methods to get an idea of what sort of UI state we can control with them. This\nwon't be an exhaustive guide - see the ````BIMViewer```` class documentation for the complete list.\n\nHaving loaded a couple of models in the previous section, let's open the viewer's Objects tab, which contains a tree\nview of the containment hierarchy of the objects within those models:\n\n````javascript\nmyBIMViewer.openTab(\"objects\");\n````\n\nTo confirm which tab is currently open:\n\n````javascript\nconst tabId = myBIMViewer.getOpenTab();\n\nconsole.log(\"Currently open tab: '\" + tabId + \"'\"); // \"objects\"\n````\n\nNow let's arrange the camera to fit an object in view:\n\n````javascript\nmyBIMViewer.flyToObject(\"1fOVjSd7T40PyRtVEklS6X\", () => { /* Done */\n});\n````\n\nTODO: Complete this section once API methods are finalized\n\n## Saving and Loading BCF Viewpoints\n\n[Bim Collaborative Format](https://en.wikipedia.org/wiki/BIM_Collaboration_Format) (BCF) is a format for managing issues\non a BIM project. A BCF record captures the visual state of a BIM viewer, which includes the camera position, the\nvisibility and selected states of the objects, and any section planes that are currently active.\n\nA BCF record saved from one BIM viewer can be loaded into another viewer, to synchronize the visual states of both\nviewers.\n\nNote that BCF viewpoints do not record which models are currently loaded. It's assumed that both the source and target\nviewers have the same models loaded.\n\nUse\nthe [````BIMViewer#saveBCFViewpoint()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html#instance-method-saveBCFViewpoint)\nto save a JSON BCF record of the current view:\n\n````javascript\nconst viewpoint = bimViewer.saveBCFViewpoint({\n // Options - see BIMViewer#saveBCFViewpoint() documentation for details\n});\n````\n\nOur viewpoint JSON will look similar to below. Before saving this viewpoint, we've hidden one object, selected another\nobject, and created section plane to slice our model. The viewpoint also contains a PNG snapshot of the viewer's canvas,\nwhich we've truncated here for brevity.\n\n````\n{\n perspective_camera: {\n camera_view_point: { x: 0.0, y: 0.0, z: 0.0 },\n camera_direction: { x: 1.0, y: 1.0, z: 2.0 },\n camera_up_vector: { x: 0.0, y: 0.0, z: 1.0 },\n field_of_view: 90.0\n },\n lines: [],\n clipping_planes: [{\n location: { x: 0.5, y: 0.5, z: 0.5 },\n direction: { x: 1.0, y: 0.0, z: 0.0 }\n }],\n bitmaps: [],\n snapshot: {\n snapshot_type: png,\n snapshot_data: \"data:image/png;base64,......\"\n },\n components: {\n visibility: {\n default_visibility: false,\n exceptions: [{\n ifc_guid: 4$cshxZO9AJBebsni$z9Yk,\n originating_system: xeokit.io,\n authoring_tool_id: xeokit/v1.0\n }]\n },\n selection: [{\n ifc_guid: \"4$cshxZO9AJBebsni$z9Yk\",\n }]\n }\n}\n````\n\nUse\nthe [````BIMViewer#loadBCFViewpoint()````](https://xeokit.github.io/xeokit-bim-viewer/docs/class/src/BIMViewer.js~BIMViewer.html#instance-method-loadBCFViewpoint)\nto load a JSON BCF record:\n\n````javascript\nbimViewer.loadBCFViewpoint(viewpoint, {\n // Options - see BIMViewer#loadBCFViewpoint() documentation for details\n});\n````\n\n# Customizing Viewer Style\n\nThe [````app/index.html````](https://github.com/xeokit/xeokit-bim-viewer/blob/master/app/index.html) file for the\nstandalone viewer contains CSS rules for the various viewer elements, which you can modify as required.\n\n## Modal Busy Dialog\n\nThe viewer displays a modal dialog box whenever we load a model. The dialog box has a backdrop element, which overlays\nthe viewer. Whenever the dialog becomes visible, the backdrop will block interaction events on the viewer's UI.\n\nWithin our [````app/index.html````](https://github.com/xeokit/xeokit-bim-viewer/blob/master/app/index.html) page, the\nmain ````<div>```` is the backdrop element:\n\n````html\n\n<div id=\"myBIMViewer\" class=\"xeokit-busy-modal-backdrop\">\n <div id=\"myExplorer\" class=\"active\"></div>\n <div id=\"myContent\">\n <div id=\"myToolbar\"></div>\n <canvas id=\"myCanvas\"></canvas>\n </div>\n</div>\n<canvas id=\"myNavCubeCanvas\"></canvas>\n````\n\nAs defined in [````css/BIMViewer.css````](https://github.com/xeokit/xeokit-bim-viewer/blob/master/css/BIMViewer.css),\nthe backdrop gets the following style, which allows the dialog to position itself correctly within the backdrop:\n\n````css\n.xeokit-busy-modal-backdrop {\n position: relative;\n}\n````\n\nIf you need to tweak CSS relating to the dialog, search for \"xeokit-busy-dialog\"\nwithin [````css/BIMViewer.css````](https://github.com/xeokit/xeokit-bim-viewer/blob/master/css/BIMViewer.css).\n\n## Tooltips\n\nTooltips are not part of the core JavaScript for the viewer. Instead, viewer HTML elements are marked\nwith ````data-tippy-content```` attributes that provide strings to show in their tooltips.\n\nFor example, the *Toggle 2D/3D* button's element looks like this:\n\n````html\n\n<button type=\"button\" class=\"xeokit-threeD xeokit-btn fa fa-cube fa-2x\" data-tippy-content=\"Toggle 2D/3D\"></button>\n```` \n\nIn the [app/index.html](https://github.com/xeokit/xeokit-bim-viewer/blob/master/app/index.html) file for the standalone\nviewer, we're using [tippy.js](https://github.com/atomiks/tippyjs), which automatically creates tooltips for those\nelements.\n\n## Customizing Appearances of IFC Types\n\nBy default, BIMViewer loads whatever object colors and opacities are in the XKT model files, without changing them.\nSometimes, however, certain types of objects may have colors that make it hard for us to view the model. \n\nFor example, in some IFC models, ````IfcPlate```` types may be used to represent windows, and those types are often given opaque \ncolors. That results in the windows of our model being opaque. For this example, we can make the windows transparent \nby configuring the BIMViewer, or just that model, with a custom color or opacity, for that ````IfcPlate```` type. That would make\nall ````IfcPlate```` types transparent again. There are two ways we can do this - programmatically via ````BIMViewer.setConfigs````, or \nfor each project individually, via the project's `index.json` file.\n\nIn the code below, we'll configure all ````IfcSpace````, ````IfcWindow````, ````IfcOpeningElement```` and ````IfcPlate```` types \nto be transparent, and while we're at it, we'll make ````IfcWindow```` types to be always blue. Note that all values are in range ````[0..1]````. \n\n---\n\n Note that prior to v2.4, BIMViewer did change the colors and opacities of `IfcOpening`, `IfcSpace`, `IfcWindow` and `IfcPlate` by \n default. We've removed that in v2.4, because it was confusing \n and users wondered why those object types did not have the colors/opacities defined for them in the model.\n\n---\n\n````javascript\n// In case the model has opaque colors for IfcSpace, IfcWindow, IfcOpeningElement and IfcPlate \n// objects, let's make those objects always transparent. To make the model look extra nice,\n// let's force IfcWindows to always be blue, while we're at it. This will apply to all models,\n// except where we override the settings per-project, as shown next.\n\nbimViewer.setConfigs({\n \"objectColors\": {\n \"IfcSpace\": {\n \"opacity\": 0.3\n },\n \"IfcWindow\": {\n \"opacity\": 0.4,\n \"color\": [0, 0, 1]\n },\n \"IfcOpeningElement\": {\n \"opacity\": 0.3\n },\n \"IfcPlate\": {\n \"opacity\": 0.3\n }\n }\n});\n````\n\nThe other way we can set these color/opacity customizations is per-project, within the ````viewerConfigs```` section of \na project's ````index.json```` file. If we've also set them via ````BIMViewer.setConFigs````, then these will override \nthe ones set via that method.\n\nAs an example, we've done this for the `OTCConferenceCenter` demo model, which otherwise has its windows opaque, which would make it hard \nfor us to navigate around that model. Therefore, we provide a custom map of colors and opacities for certain IFC types via \nthe ```viewerConfigs``` in the [project ````index.json```` for that model](https://github.com/xeokit/xeokit-bim-viewer/blob/master/app/data/projects/OTCConferenceCenter/index.json), as shown below.\n\n````json\n{\n \"id\": \"otcConferenceCenter\",\n \"name\": \"OTC Conference Center\",\n \"models\": [\n {\n \"id\": \"design\",\n \"name\": \"OTC Conference Center Design\"\n }\n ],\n \"viewerConfigs\": {\n \"backgroundColor\": [\n 0.95,\n 0.95,\n 1.0\n ],\n \"objectColors\": {\n \"IfcSpace\": {\n \"opacity\": 0.3\n },\n \"IfcWindow\": {\n \"opacity\": 0.4\n },\n \"IfcOpeningElement\": {\n \"opacity\": 0.3\n },\n \"IfcPlate\": {\n \"opacity\": 0.3\n }\n }\n },\n \"viewerContent\": {\n \"modelsLoaded\": [\n \"design\"\n ]\n },\n \"viewerState\": {\n \"tabOpen\": \"objects\",\n \"expandObjectsTree\": 3,\n \"expandClassesTree\": 1,\n \"expandStoreysTree\": 1\n }\n}\n````\n\n\n## Localizing a Viewer\n\nThe easiest way to localize a BIMViewer is by loading translation strings into its locale service, which is implemented\nby a\nxeokit [LocaleService](https://xeokit.github.io/xeokit-sdk/docs/class/src/viewer/localization/LocaleService.js~LocaleService.html)\n.\n\nThe snippet below shows how it's done, using a partial set of the translations expected by the components\nwithin the BIMViewer. We'll just show the translations for the faces of the NavCube. We'll also load the translations\ninline, rather than fetch them from a separate JSON file, as we would in practice.\n\nWe call translations \"messages\". Our metaphor is that the UI \"conveys messages to the user\".\n\nTo see all the translations expected by a BIMViewer, take a look at the translations we've configured for the bundled\nBIMViewer\ndemo application: [````/app/locales/messages.js````](/app/locales/messages.js).\n\n````javascript\nmyBIMViewer.localeService.loadMessages({\n \"en\": { // English\n \"NavCube\": {\n \"front\": \"Front\",\n \"back\": \"Back\",\n \"top\": \"Top\",\n \"bottom\": \"Bottom\",\n \"left\": \"Left\",\n \"right\": \"Right\"\n },\n //..\n },\n \"mi\": { // Māori\n \"NavCube\": {\n \"front\": \"Mua\",\n \"back\": \"Tuarā\",\n \"top\": \"Runga\",\n \"bottom\": \"Raro\",\n \"left\": \"Mauī\",\n \"right\": \"Tika\"\n },\n //..\n },\n \"fr\": { // French\n \"NavCube\": {\n \"front\": \"Avant\",\n \"back\": \"Arrière\",\n \"top\": \"Supérieur\",\n \"bottom\": \"Inférieur\",\n \"left\": \"Gauche\",\n \"right\": \"Droit\"\n },\n //..\n },\n \"jp\": { // Japanese\n \"NavCube\": {\n \"front\": \"前部\",\n \"backLabel\": \"裏\",\n \"topLabel\": \"上\",\n \"bottomLabel\": \"底\",\n \"leftLabel\": \"左\",\n \"rightLabel\": \"右\"\n },\n //..\n },\n});\n````\n\nOnce we've loaded our translations, we can switch the BIMViewer between locales like so:\n\n````javascript\nmyBIMViewer.localeService.locale = \"jp\";\n````\n\n# xeokit Components Used in the Viewer\n\nThe viewer is built on various [xeokit SDK](http://xeokit.io) components and plugins that are designed to accelerate the\ndevelopment of BIM and CAD visualization apps.\n\nThe table below lists the main ones used in this viewer.\n\n| Component | Purpose | \n|:-----------------------|:------------------|\n| [````Viewer````](https://xeokit.github.io/xeokit-sdk/docs/class/src/viewer/Viewer.js~Viewer.html) | The WebGL-based viewer at the heart of ````BIMViewer````. |\n| [````XKTLoaderPlugin````](https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js~XKTLoaderPlugin.html) | Loads model geometry and metadata. |\n| [````NavCubePlugin````](https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/NavCubePlugin/NavCubePlugin.js~NavCubePlugin.html) | Navigation cube gizmo that allows us to rotate the scene and move the camera to look at it along a selected axis or diagonal. |\n| [````TreeViewPlugin````](https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/TreeViewPlugin/TreeViewPlugin.js~TreeViewPlugin.html) | Implements the Objects, Classes and Storeys tree views within the explorer panel. |\n| [````SectionPlanesPlugin````](https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/SectionPlanesPlugin/SectionPlanesPlugin.js~SectionPlanesPlugin.html) | Manages interactive section planes, which are used to slice objects to reveal inner structures. |\n| [````BCFViewpointsPlugin````](https://xeokit.github.io/xeokit-sdk/docs/class/src/plugins/BCFViewpointsPlugin/BCFViewpointsPlugin.js~BCFViewpointsPlugin.html) | Saves and loads BCF viewpoints. |\n| [````ContextMenu````](https://xeokit.github.io/xeokit-sdk/docs/class/src/extras/ContextMenu/ContextMenu.js~ContextMenu.html) | Implements the context menus for the explorer tree views and 3D canvas. |\n\n# Building the Viewer\n\n## Installing from NPM\n\nTo install the npm package:\n\n````\nnpm i @xeokit/xeokit-bim-viewer\n````\n\n## Building the Binary\n\nRun the command below to build the ES6 module in ````/dist/xeokit-bim-viewer.es.js````.\n\n````\nnpm run build\n````\n\n## Building the Documentation\n\nTo build the API documentation in ````/docs/````:\n\n````\nnpm run docs\n````\n\n\n\n\n\n",
