This is arguably the most critical feature for any AutoCAD alternative. AutoCAD’s native file format is .dwg, and .dxf (Drawing Exchange Format) is its open standard counterpart. If you frequently exchange files with others who use AutoCAD, or if you have a large existing library of .dwg drawings, robust compatibility is non-negotiable.

• Why it’s important:
  • Seamless Collaboration: Ensures you can open, edit, and save files without data loss or corruption, allowing smooth teamwork with AutoCAD users.
  • Legacy Data Access: Protects your investment in years of .dwg files, allowing you to continue working with them.
  • Industry Standard: Many clients, suppliers, and regulatory bodies still demand .dwg submissions.
• What to look for:
  • Native DWG Support: The ability to directly open, edit, and save .dwg files without conversion. (e.g., nanoCAD Free often provides this for older .dwg versions).
  • Excellent DXF Support: While not native .dwg, strong .dxf import/export capabilities are vital. Most free CAD software handles .dxf well.
  • Version Compatibility: Ensure the software supports the .dwg or .dxf versions you typically encounter (e.g., AutoCAD 2018, 2013, 2010 formats). Some free tools might only support older versions.
  • Layer and Block Preservation: Verify that layers, blocks, attributes, and text styles are preserved accurately during import/export.
  • Examples: nanoCAD Free (direct DWG), LibreCAD/QCAD (strong DXF). FreeCAD can import/export DXF, and DWG via external converters.

Core 2D Drafting Tools and Precision Features

For many, AutoCAD is synonymous with precise 2D drafting. Any viable alternative must offer a comprehensive set of tools for creating accurate technical drawings.
