Batch CAD/BIM to XLSX/DAE Converter with Validation & Reporting

This n8n workflow automates the batch conversion of CAD/BIM files (.rvt, .ifc, .dwg, .dgn) from a source folder (including subfolders) to analysis-ready XLSX spreadsheets and optional DAE models. It leverages the local RvtExporter.exe tool via PowerShell on Windows, supporting configurable export modes: basic (~309 categories), standard (~724), complete (~1209), or custom. Additional flags enable bounding box exports, Revit schedules, and PDF sheets, with options to skip XLSX or DAE outputs.

For each file, the workflow executes the converter, verifies output existence and file sizes, logs successes/failures, and aggregates results. Upon completion, it produces a comprehensive HTML summary report detailing processed files, conversion stats, errors, and links to outputs, which opens automatically. This ensures reliable, hands-off processing with full traceability.

Ideal for real estate professionals, architects, and BIM analysts needing to extract structured data from design files for lead management, property analysis, cost estimation, or inventory reporting. Benefits include massive time savings on manual exports, reduced errors via validation, scalability for large folders, and customizable outputs tailored to project needs. Prerequisites: Windows with DDC Revit toolkit installed.
