ACC Get AEC Model Basic Data

The ACC Get AEC Model Basic Data node retrieves basic data for elements within Autodesk Construction Cloud (ACC) AEC Data Models using a simple GraphQL query based on provided filters and element groups.

Purpose

Use this node to quickly extract basic model data for specified elements and properties without requiring advanced AI-based parsing or complex query building.

Inputs

Field Label	Input Type	Description
Element Id	Text	The ID of the element group within the AEC Data Model to query.
Filter	Text	A GraphQL-compatible filter string to restrict which elements are returned (e.g. category or property filters).
Return Properties	JSON Array	A list of property names to include in the returned data (e.g. ["Width","Height","Family Name"]).

Outputs

Output Variable	Description
AecData	The JSON string result containing a list of elements with their requested properties.

Functionality

This node:

1. Validates required inputs (Element Id, Filter, Return Properties).
2. Retrieves the Autodesk service account token from stored credentials.
3. Executes a simple GraphQL query against the AEC Data Model API for the specified element group and filter.
4. Returns the retrieved elements as a JSON string in the AecData output variable.

Example Use Case

✅ Retrieve all walls in a model with their height, width, and type properties for quantity take-off reports.
✅ Extract door elements with their family name and dimensions for an automated door schedule export.

Task Success Criteria

• Success: Elements are retrieved from the AEC Model and stored as AecData.
• Failure: If the service account is invalid, or if data retrieval fails, the task fails with a descriptive error message indicating the failure point.

Notes

• Ensure the ThirdParty-Autodesk service account is configured with valid credentials and has access to the relevant AEC Data Models.
• The Return Properties input must be a JSON array of property names to include in the output.
• The output (AecData) is a JSON string representing a list of ElementResult objects as returned by the ACC API integration.
