Validate CAD/BIM Files Against Excel Standards (Revit,IFC,DWG,DGN)

This n8n workflow provides a powerful CAD-BIM multi-format validation pipeline for self-hosted instances using community nodes. It processes Revit (.rvt), IFC (.ifc), AutoCAD DWG, and DGN files by converting them into open data tables, then runs automated checks on naming conventions, model structure, attributes, and completeness against configurable Excel rules.

Key benefits include significant time savings in manual quality checks for construction and engineering projects, standardized compliance enforcement, and generation of actionable error summaries plus Quantity Take-Off (QTO) tables. Outputs are downloadable as Excel files, facilitating easy review and integration into project workflows.

Ideal use cases span AEC firms for BIM coordination, clash detection prep, and regulatory compliance; consultancies automating ETL pipelines; and teams ensuring data quality before federated models. Requires converter executables like RvtExporter in specified paths; troubleshoot via logs in /output. Full docs on GitHub.
