Revit Export (APS-DA) ​
Exports a Revit file hosted in Autodesk Construction Cloud to PDF or another CAD format using the APS Design Automation service. The export runs server-side — no local Revit installation is required.
Purpose ​
Use this task when a workflow needs to produce a PDF or CAD export from a Revit model stored in ACC. The task resolves the file from ACC, submits a Design Automation work item against the Revit cloud engine, polls until completion, and downloads the output file to the workflow's working folder for use by downstream tasks.
The AppBundle and Activity are automatically registered and kept up to date in APS — no manual Design Automation setup is required.
Inputs ​
| Field | Type | Required | Description |
|---|---|---|---|
| Hub Name | Text | Yes | The name of the ACC Hub as shown in the ACC web app. |
| Project Name | Text | Yes | The name of the ACC project containing the Revit file. |
| File | Text | Yes | The Revit file to process. Can be a full folder path (e.g. Project Files/Models/building.rvt), a lineage URN, or a version URN. |
| Operation | Dropdown | Yes | The export operation to run: Export PDF or Export Model. |
| Export Format | Dropdown | Yes (Export Model only) | The file format to export: IFC (open BIM coordination), DWG or DGN (CAD workflows), or STEP (solid geometry, Revit 2025+). Only shown when Operation is Export Model. |
| External IDs | Multi-line Text | No (Export Model only) | Optional JSON output from a Query AEC Elements node. When provided, only the matched elements are exported. Leave blank to export the entire model. Only shown when Operation is Export Model. |
Outputs ​
| Name | Description |
|---|---|
| OutputFilePath | The local file path of the exported file (PDF, IFC, DWG, DGN, or STEP) in the workflow working folder. Pass this to downstream tasks such as Add ACC File to upload the result. |
| OutputContent | The text content of the output file. Only populated for text-based outputs (e.g. family listing). Empty for binary formats like PDF or IFC. |
| WorkItemId | The APS Design Automation work item identifier. Useful for troubleshooting. |
| ReportUrl | URL to the Design Automation execution report log. Useful for debugging failures. |
Token consumption
This task uses the APS Design Automation service, which consumes Autodesk Platform Service tokens (cloud credits) each time a work item runs. Token usage varies by file size and processing time. Monitor your token balance using the APS Contract Usage node or the Autodesk account portal to avoid unexpected costs.
Autodesk API token usage
Autodesk frequently update their token consumption policies and the cost of individual API operations. Refer to the Autodesk Platform Services Token Usage documentation for current pricing and consumption details.
Authentication ​
This node requires an Autodesk service account or third-party account with Client ID and Client Secret configured. Design Automation requires 2-legged authentication — accounts using only 3-legged OAuth tokens will fail.
