Cad2data Revit IFC DWG DGN
Open-source CAD-to-table pipeline converting Revit, IFC, DWG, DGN into analysis-ready data on Windows.
Cad2data is a pragmatic, no-nonsense tool for teams that value data ownership over a polished GUI. If your workflow is CLI-driven and you need bulk CAD-to-table conversion without cloud dependency, this is a solid open-source pick. But if you expect a visual viewer or turnkey SaaS, look elsewhere. It competes with proprietary converters like Autodesk Platform Services, but offers no recurring costs and full data control, at the price of a steeper learning curve.

About Cad2data Revit IFC DWG DGN
Cad2data Revit IFC DWG DGN is an open-source command-line tool that converts locked CAD and BIM files into structured, analysis-ready tables. It extracts data from Revit (.rvt), IFC (.ifc), DWG (.dwg), and DGN (.dgn) files locally on Windows, outputting CSV, Excel, or JSON. Built for AEC professionals, it enables automated quantity takeoff, cost estimation, and BOQ generation without cloud dependency or per-model fees. The tool focuses on data extraction, not visual model interaction, and is designed for CLI-driven workflows. It integrates with the OpenConstructionERP ecosystem and can be triggered via CLI or REST API for AI agent integration. Self-hosted and offline, it ensures data sovereignty. Key features include batch processing, element property and geometry metadata extraction, automated recurrent conversion pipelines, and AGPL-3.0 licensing. Compared to cloud services like Autodesk Platform Services, Cad2data offers absolute data control and no recurring costs, but requires comfort with command-line tools and manual installation. It's ideal for estimators, BIM managers, and automation engineers who prioritize repeatable data extraction over visual model interaction.
Behind the Verdict
Cad2data fills a specific niche: automated, repeatable extraction of structured data from CAD/BIM files into tables. Its strengths are clear: it's open-source (AGPL-3.0), runs locally on Windows, handles multiple formats (Revit, IFC, DWG, DGN), and outputs to CSV, Excel, or JSON. The batch processing and scheduled pipelines make it a good fit for organizations that need to regularly convert large numbers of files. Integration with OpenConstructionERP and AI agents (via REST API) adds value for teams building automated workflows. Weaknesses are equally clear: no GUI, command-line only, Windows-only, and performance can be slow on large Revit models due to COM automation overhead. There's no built-in scheduling, so you must pair it with a task scheduler. The tool does not provide visual model interaction, which some users might expect. Where it fits: teams that are comfortable with CLI tools, have a Windows environment, and need a cost-effective (free) way to convert CAD/BIM data into tables for downstream analysis or AI processing. It's particularly strong for estimators, BIM managers, and automation engineers who value data sovereignty and want to avoid cloud lock-in. Where it doesn't fit: teams that need a visual BIM viewer, a GUI, or a fully managed cloud service. It also may not suit users who prefer SaaS delivery or real-time collaboration on CAD data. Overall, if you're willing to invest in learning the CLI and setting up your own scheduling, Cad2data offers a powerful, free, and transparent way to unlock data from CAD/BIM files.

Real-world workflow fit
Concrete scenarios for the personas Cad2data Revit IFC DWG DGN actually fits — and what changes day-one when you adopt it.
You need to extract element properties from a weekly Revit model export for cost estimation.
Outcome: Use the CLI to convert the .rvt file to CSV, then feed the output into your cost database automatically via scheduled task.
You receive hundreds of DWG files from subcontractors and need a unified material takeoff.
Outcome: Batch process all files with a single command, generating a combined takeoff table in Excel without manual data entry.
You're building a construction automation workflow that requires up-to-date BIM data.
Outcome: Use the REST API to trigger conversion on new IFC files and feed the JSON output directly into your AI agent's knowledge base.
Use Cases
- Convert weekly Revit model exports into a structured cost database for estimation.
- Automate IFC property extraction to populate an AI agent’s knowledge base.
- Batch process hundreds of DWG files to create a unified material takeoff table.
- Integrate with OpenConstructionERP to auto-populate cost items from BIM elements.
Limitations
- Requires local Windows machine (no cloud execution).
- No GUI – all operations via CLI.
- Converting large Revit models may be slow due to COM automation overhead.
- No built-in scheduling; must be paired with cron/task scheduler.
