In just a few minutes, Claude or ChatGPT can now generate a fully functional n8n pipeline that:

✅ Opens and structures closed and complex CAD data
✅ Extracts BIM quantities (QTO) from .rvt, .ifc, or .dwg files
✅ Transforms and aggregates data (e.g., by "Type Name" or "Category")
✅ Generates clean HTML reports with summaries and visual structure

And the best part?
No plugins. No APIs. No Revit. No Autodesk®. No manual processing.
Just one click — and the entire ETL chain is done. These tools were built for some of the leading construction and design companies, and now they’re available to everyone.

🔁 This isn’t just automation — it’s a paradigm shift:
Instead of manually grouping elements and cleaning up schedules, a BIM coordinator now:
▪️ Defines rules once (for example: group by OST_Walls, sum by Volume)
▪️ Runs the pipeline
▪️ Gets clean, structured results instead of “raw” models from Revit or IFC

💡 This approach:
▪️ Eliminates routine manual tasks
▪️ Reduces errors
▪️ Makes CAD/BIM data transparent, reusable, and accessible

📊 Example workflow:
→ Upload 5 Revit files
→ Pipeline extracts 100,000+ elements
→ Filters only OST_Walls
→ Aggregates volumes by Type Name
→ Generates an HTML dashboard in 30 seconds

✨ BIM coordination and BIM management become Data Supervision
With ETL + AI + n8n, we’re not just accelerating BIM — we’re replacing legacy workflows entirely.
No cloud APIs. No license headaches. Only open and free tools, with your data staying fully in your control.
