It supports sketching and constraining in both 2D and 3D, solid modeling operations such as extrude, lathe, revolve, loft, pipe, chamfer, and fillet, and measurement-driven modeling.\n\nThe application is desktop software for Linux and Windows, with source code and releases hosted on GitHub. Dune 3D can import STEP models for reference or integration, import DXF files and bitmap pictures, and export STL, STEP, DXF paths, SVG paths, and projections depending on the workflow. It is free and open source under GPL-3.0+.", "key_functions": "Parametric 3D CAD, 2D and 3D constraints, STEP import/export, STL export, DXF import/export, chamfers, fillets", "category": {"name": "CAD", "slug": "cad"}, "tags": [{"name": "2D", "slug": "2d"}, {"name": "3D", "slug": "3d"}, {"name": "Free", "slug": "free"}, {"name": "Mechanical", "slug": "mechanical"}, {"name": "Open Source", "slug": "open-source"}], "deployment_types": ["On-premise"], "pricing_models": ["Free"], "business_sizes": ["Small", "Mid-size"], "website_url": "https://dune3d.org/", "company_name": "Lukas K.", "platforms": "Linux, Windows", "latest_version": "1.4.0", "pricing_tiers": [{"name": "Free", "price": null, "period": "", "description": "Free and open-source desktop application.", "is_quote_based": false}], "updated_at": "2026-06-08T01:14:19.167Z"}
