# Contextualize point clouds in data modeling projects

> Use 3D jobs to generate point cloud volume suggestions and the point cloud contextualization API to create approvals that link suggested volumes to CogniteAsset instances.

## Contextualize

In **data modeling** projects, generate point cloud volume suggestions as part of point cloud processing, then create contextualization approvals that link volumes to <span translate="no">CogniteAsset</span> instances.

<Steps>
  <Step title="Get point cloud volume suggestions">
    Point cloud volume suggestions are produced during point cloud processing when you enable volume generation in the job configuration.

    Run the 3D job through the [Create a job using 3D source data](https://docs.cognite.com/20230101/3d-jobs/create-a-job-using-3d-source-data) API endpoint.

    In the request body, enable the point cloud pipeline option for creating volumes (under `configuration` → `pipelineConfiguration` → `processTilesOptions`).
  </Step>

  <Step title="Create contextualization approvals">
    To create approvals that connect suggested volumes to <span translate="no">CogniteAsset</span> instances, use the [Create point cloud volume contextualization](https://api-docs.cognite.com/20230101-beta/tag/3D-Contextualization/paths/~13d~1contextualization~1pointcloud/post) API endpoint ([*public preview*](/cdf/product_feature_status)).
