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

# CAD2DAA: 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:\DDC_Converter_Revit\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: - `converter_path`: `C:\DDC_Converter_Revit\datadrivenlibs\RvtExporter.exe` - `source_folder`: folder with your projects - `output_folder`: folder for results - `include_subfolders`: `true` / `false` - `file_extension`: `.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. ## Outputs - `*_ext.xlsx` - tabular data per input file. - `*_ext.dae` - lightweight 3D (if not disabled with `-no-collada`). - `CAD_Conversion_Report_YYYY-MM-DD_HH-MM-SS.html` - summary with: - success rate and progress - per-file and total processing time - input/output sizes and file paths ## Notes & tips - Uses PowerShell `Get-ChildItem` for discovery and `cmd /c start` to open the report. - With `-no-collada`, success/verification is XLSX-only (DAE is skipped). - Prefer ASCII paths and ensure write permissions in the output folder. ## Categories Data Extraction Files & Storage EL CAD/BIM ## Tags `cad-bim`, `revit`, `ifc`, `dwg`, `dgn`, `converter`, `batch`, `xlsx`, `dae`, `qto` ## Author DataDrivenConstruction.io ## Author [DataDrivenConstruction.io](https://DataDrivenConstruction.io) [info@datadrivenconstruction.io](mailto:info@datadrivenconstruction.io) ## Consulting and Training We work with leading construction, engineering, consulting agencies, and technology firms around the world to help them implement open data principles, automate CAD/BIM processing, and build robust EL pipelines.
