Cad2data Revit IFC DWG DGN

Cad2data fills a specific niche: converting proprietary CAD/BIM files into structured data on your own hardware. It's not a BIM viewer or a design tool — it's an ETL pipeline for the construction industry. The AGPL-3.0 license ensures full control, and the integration with OpenConstructionERP makes it part of a larger open-source construction stack. When to pick this: you're a BIM manager or estimator who needs to regularly extract quantities, properties, and metadata from Revit, IFC, DWG, or DGN files and pipe them into a database, spreadsheet, or AI workflow. You're comfortable running Python scripts and using a command line. You want to avoid cloud subscription costs and data residency issues. When to pass: your team expects a graphical interface to preview models before export. You need real-time collaboration on the extracted data. Your IT policy prohibits running custom Windows executables or Python scripts. A cloud-first or SaaS model suits your workflow better. Compared to the closest alternative — Autodesk Platform Services (formerly Forge) — Cad2data is free and self-hosted but lacks APS's cloud scalability, model viewer, and extensive API. APS charges per model conversion and requires internet connectivity. Cad2data trades convenience for sovereignty and cost. In practice, the pipeline works reliably for well-formed files, but edge cases (corrupt files, unusual schema extensions) can require manual debugging. The documentation assumes familiarity with construction data schemas. Support is community-driven or paid consulting. Bottom line: a no-frills open-source tool that delivers exactly what it promises — no more, no less. Ideal for automation-savvy teams committed to open-source principles.
