Batch Convert CAD/BIM Files to XLSX/DAE with Validation and Reporting

CAD2DATA: Batch Converter (Revit/IFC/DWG/DGN → XLSX/DAE)

Batch-convert CAD/BIM files to analysis-ready XLSX and optional DAE with automatic verification and a clean HTML report. Runs locally via RvtExporter.exe and PowerShell on Windows.

Supports configurable export modes — basic (~309 categories), standard (~724), and complete (~1209) — plus optional outputs such as bounding boxes, Revit schedules, and PDF drawings.

What it does - Scans a source folder (optionally including subfolders) for .rvt, .ifc, .dwg, or .dgn. - For each file, runs: RvtExporter.exe [input] [output.xlsx] [output.dae] [options]. - Verifies outputs (existence + size) and aggregates results. - Generates a summary HTML report and opens it automatically on completion.

Converter options - Export modes: basic | standard | complete | custom - Flags: bbox (BoundingBox to XLSX), schedule (Revit schedules), sheets2pdf (Sheets → PDF) - Disable: -no-xlsx, -no-collada - Custom files: [<output file>] and [<category file>] (used with custom)

Examples - basic bbox — minimal export + BoundingBox - complete schedule sheets2pdf — full export + schedules + PDFs - standard -no-collada — XLSX only (skip DAE)

Prerequisites - Windows host (PowerShell + local executable). - DDC Revit toolkit installed: C:\DDCConverterRevit\datadrivenlibs\RvtExporter.exe - Read access to the source folder and write access to the output folder.

How to use 1. Import this JSON workflow into n8n. 2. Open Set Configuration Parameters and set: - converterpath: C:\DDCConverterRevit\datadrivenlibs\RvtExporter.exe - sourcefolder: folder with your projects - outputfolder: folder for results - includesubfolders: true / false - fileextension: .rvt | .ifc | .dwg | .dgn - options: see Converter options 3. Run Manual Trigger. 4. The workflow discovers files → runs conversions → verifies outputs → writes and opens the HTML report.
