Evo Block Model API Client

The Block Model API provides the ability to manage and report on block models in your Evo workspaces. Enable your product with Evo connected workflows by integrating with the Seequent Block Model API.

The Block Model API supports a range of sub-blocking options, and both full and partial updates to block models, including updates of specified columns and/or sub-volumes. Block models are versioned, and the service supports reporting on the material content of current or previous versions, and comparing the content between versions of a block model.

Pre-requisites

• Python ^3.10
• An application registered in Bentley

Installation

pip install evo-blockmodels

Usage

See the evo-sdk-common documentation for information on how to authenticate, then select the organisation, hub and workspace that you would like to use.

service_client = BlockModelAPIClient(environment, connector)
service_health = await service_client.get_service_health()
service_health.raise_for_status()
