Discover how to build powerful cloud-based engineering applications that access BIM data directly from Autodesk Construction Cloud - without requiring local Revit installations. This session demonstrates integrating VIKTOR.AI, a low-code Python platform, with Autodesk's AEC Data Model GraphQL API. Learn how to authenticate using OAuth 2.0, query hubs, projects, and models, and extract element properties from Revit files stored in ACC. We'll walk through a working proof-of-concept that browses ACC structure, retrieves model element groups, and queries BIM elements by category - all through a web interface. This approach enables engineers to automate data extraction, generate reports, and build custom workflows without desktop applications, opening new possibilities for cross-disciplinary collaboration and cloud-native AEC solutions.
