AEC Data - AI

Queries an Autodesk Construction Cloud AEC model for specific building elements using a natural language description interpreted by AI.

Purpose

Use this task when a workflow needs to extract BIM element data from an ACC model but the selection criteria is expressed in plain language rather than a precise filter query. The task interprets the input text using AI to identify which object categories and family names match the intent, then fetches the corresponding elements and their requested properties. It handles both general queries and level-specific queries automatically.

Inputs

Field	Type	Required	Description
Revit AEC Element Id	Text	Yes	The element group ID for the AEC model to query. This can be found by navigating to the element in Mesh and checking the URL.
Model Information Context	Multi-line Text	Yes	Background information about the model that helps the AI interpret the query correctly, including details about the model's purpose, structure, and organisation.
Model Input Text	Multi-line Text	Yes	The natural language description of the elements to retrieve (e.g. Show me all the doors on Level 2).
Return Properties	List	No	The list of property names to include in the returned element data (e.g. Name, Width, Family Name).

Outputs

Name	Description
AecData	A JSON string containing the elements returned from the AEC model that matched the AI-interpreted query, including the requested properties. Pass this to a data transformation or reporting task for further processing.
