# Native plugins

The BIMDataViewer is shipped with native plugins that allow basic interaction with ifcs/models. To enabled/disabled/configure them, use their name with the corresponding configuration on the plugins section of the makeBIMDataViewer configuration object.

Example:

const viewer = makeBIMDataViewer({
  plugins: {
    viewer3d: {
      navCube: false,
    },
    split: true,
    "structure-properties": {
      merge: true,
    },
  },
});

Some plugins have instance API that can be used to interact with them:

Example:

$viewer.globalContext
  .getPlugins("structure-properties")
  .forEach((plugin) => plugin.reloadTrees());

# BCF

name: bcf

The BCF plugin allows to interact with the BIMData BCF API by default. It is possible to change the target API using its configuration.

# Configuration

`apiUrl`	`string`	The BCF API URL.	BIMData API URL	1.2.0
`projectId`	`object`	Override the project ID	viewer's project id	1.2.0
`fetchUsers`	`async function`	Define another method to fetch user list (used in `assigned_to` field)	null	1.3.0
`mergeUsers`	`boolean`	Set if users fetched with fetchUsers must be merged with users on BIMData API or should override the list	true	1.3.0
`fetchCurrentUser`	`async function`	Change the method to retrive BCF current-user. Defaults to BCF standard method. Must be return the same object than standard current-user route. Emitted BCF Topics and Comments will use the id of the current user	null	1.4.0

# Instance API

Name	Description
`reload(): void`	Reload the trees of the loaded IFCs.

# Structure and properties

name: structure-properties

This plugin is actually two plugins merged together. The structure plugin that displays the tree structures of the IFCs. The properties plugin that displays the properties of the selected objects.

# Configuration

Name	Type	Description

`edges`	`boolean`	Default to `true`. Add model edges.
`enableOffsets`	`boolean`	Default to `False`. Allow model objects to be translated. This increase GPU memory usage

# Events

Name	Payload	Description	Emitted on
`3d-model-loaded`	`{ ifc, model, plugin }`	Emitted when a 3D model is loaded.	`localContext` and `globalContext`

# Instance API

This API is available from this object on the 3d window:

const viewer3dPlugin = this.$viewer.localContext.getPlugin("viewer3d");
