This n8n workflow automates the process of validating CAD and BIM project files such as Revit, IFC, DWG, and DGN. It starts with a manual trigger, sets up file paths for project and validation rules, and intelligently handles file conversions if necessary. The core of the workflow involves reading project data and validation rules from Excel files, then executing a Python script within n8n to perform detailed validation checks against predefined criteria. Results are written back into an Excel report, highlighting missing or inconsistent data with color codes for quick visual assessment. The process culminates in saving and automatically opening the validation report for review.
This workflow is particularly useful for architects, engineers, and construction professionals who need to ensure data integrity across multiple CAD/BIM formats, streamline quality control, and minimize manual data verification. It supports project standardization, quality assurance, and documentation efforts by automating repetitive validation tasks and providing instant, clear feedback on data completeness and compliance.
