Synchronization

---

This endpoint is used to create CombinePhysicalModels configuration.

Combine Physical Models transformation combines the source iModel's top level hierarchy physical models to a desired amount of models.
More information about internal iModel structure can be found [here](https://www.itwinjs.org/bis/intro/information-hierarchy/#example-information-hierarchy).

This transformation is usually leveraged to improve performance of iModel viewers. Lack of performance is noticeable when model counts reach ~1000 or even more models.
It is recommended to set the numberOfModels property to ~ 5-20 and test the performance of the iModel.

Configuration specific properties explained:
```
numberOfModels - specify amount of models to transform the source iModel into.
simplifyGeometry - optional parameter indicating if geometry simplification should be used (transforming parasolids to meshes). Default if not specified - false.
```

Creating a configuration does not actually run the transformation. To run the transformation check out POST [/transformations](/apis/transformations/operations/create-transformation/) reference.

### Authentication

Requires `Authorization` header with valid Bearer token for scope `transformations:modify`.

For more documentation on authorization and how to get access token visit [OAUTH2 Authorization](https://developer.bentley.com/apis/overview/authorization/) page.

### Authorization

User must have `imodels_write` permission assigned at the iModel level and at least `imodels_webview` permission assigned at the Project level. If permissions at the iModel level are not configured, then user must have `imodels_write` permission assigned at the Project level.

Alternatively the user should be an Organization Administrator for the Organization that owns a given Project the iModel belongs to.

An Organization Administrator must have at least one of the following roles assigned in User Management: Account Administrator, Co-Administrator, or CONNECT Services Administrator. For more information about User Management please visit our Bentley Communities [Licensing, Cloud, and Web Services](https://communities.bentley.com/communities/other_communities/licensing_cloud_and_web_services/w/wiki/50711/user-management-2-0) wiki page.

delete-configuration

configurationId

Deletes the configuration for the given ID and returns it.

Configuration with the given ID does not exist.

---

This endpoint is used to create a configuration for filtering iModel data based on a view definition.

A View renders geometry from one or more Models of an iModel in a web browser. A View is an element of the ViewDefinition class. More information [here](https://www.itwinjs.org/learning/frontend/views/).

FilterByViewDefinition transformation is filtering out all of the data not associated to the models and categories specified for the transformation.

This transformation is usually leveraged to filter out unnecessary data and align an iModel to the view within a browser window.

Configuration specific properties explained:

```
models - ids of models contained within a view definition.
categories - ids of categories contained within a view definition.
neverDrawn - element ids which should be left out of the target iModel
subCategoryOvr
    - subCategory - id of sub category 
    - invisible - geometry belonging to an invisible subCategory will be left out of target iModel
clip - data needed to create clipping.
    - shapes - array of shape clippings
        - points - array of number arrays describing the polygon. Each low level array contains numbers corresponding to coordinates [x, y, z]
        - trans - array of number arrays describing the transform applied to the polygon. Each low level array contains 4 numbers of a transform row [qx, qy, qz, ax].
        - zlow - lower bound on Z.
        - zhigh - upper bound on Z.
        - mask - `true` if this shape is a mask.
        - invisible -`true` if this shape is invisible.
    - planes - array of plane line clippings
        - invisible -
        - clips - a union of plane clip set intersections
            - normal - the plane's inward normal as a number array corresponding to coordinates [x, y ,z].
            - dist - the plane's distance from the origin.
            - invisible - `true` if this plane is invisible.
            - interior - `true` if this plane is interior.
perModelCategoryVisibility - array of objects containing perModelCategoryVisibility data
    - modelId - id of model for which category override will apply.
    - categoryId - id of category for which the ovveride will apply.
    - visible - boolean flag indicating if category is visible for the given model.
```

All ids must be well-formed valid hexadecimal ids conforming with [iTwin.js specification](https://www.itwinjs.org/learning/common/id64/?term=id64).

PerModelCategoryVisibility override affects geometry on all subcategories belonging to the overridden category. That is, if the category is overridden to be visible, then geometry on all subcategories of the category will be visible, regardless of any subCategory overrides.

Creating a configuration does not actually run the transformation. To run the transformation check out POST [/transformations](/apis/transformations/operations/create-transformation/) reference.

### Authentication

filterbyviewdefinition

Returns the created configuration for filtering by a view definition transformation.

---

This endpoint is used to create a configuration for filtering iModel data based on an ECSql query.

ECSQL is a text-based command language for CRUD (create, read, update, delete) operations against the business data in an iModel or ECDb file. More information, samples and tutorials [here](https://www.itwinjs.org/learning/ecsql/).

Configuration specific properties explained:

```
ecSql - ECSql query that only selects ECInstanceIds of elements that the iModel will be filtered by.
inclusive - 'false' when all elements selected by ecSql query are filtered out, 'true' when all physical elements that are not selected by ecSql query are filtered out. By default it is 'false'.
```

Creating a configuration does not actually run the transformation. To run the transformation check out POST [/transformations](/apis/transformations/operations/create-transformation/) reference.

### Authentication

Requires `Authorization` header with valid Bearer token for scope `transformations:modify`.

filterimodel

Returns the created configuration for filtering iModel by ECSql query.

---

This endpoint is used to create a configuration for filtering out geometry entries based on their sub-category names


A SubCategory is a subdivision of a Category. SubCategories allow elements in iModel to have multiple pieces of geometry that can be independently visible and styled (color, linesStyle, transparency, etc.). More information [here](https://www.itwinjs.org/bis/intro/categories/#subcategories).

FilterSubCategories transformation is filtering out all of the data associated to subCategoryNames specified for the transformation.

Configuration specific properties explained:

```
subCategoryNames - array of sub category names.
```

Creating a configuration does not actually run the transformation. To run the transformation check out POST [/transformations](/apis/transformations/operations/create-transformation/) reference.
