1. Best for 2D Drafting (Replacing AutoCAD LT) LibreCAD
Type: Open-source, completely free. Strengths: Excellent for floor plans, schematics, and technical drawings. Uses the familiar .DXF format. Limitations: No 3D capabilities. No native .DWG save (only export). Best if: You need a lightweight, fast 2D-only tool.
NanoCAD (Free version)
Type: Freemium (free version is limited to 2D). Strengths: Uses native .DWG files (same as AutoCAD) without conversion. Almost identical command line and interface to AutoCAD. Limitations: Free version is 2D only, no 3D, no external references (Xrefs), no scripting. Best if: You are an AutoCAD user who needs to work with standard .DWG files without paying.
QCAD (Community Edition)
Type: Open-source core (CE) + paid Pro. Strengths: Very stable, great for precise 2D technical drawings. Has a powerful layer and block system. Limitations: Community Edition lacks some Pro features (like TrueType text, printing optimizations). Native format is .DXF . Best if: You want a polished, professional 2D tool and can live with minor limitations. alternativas a autocad gratis
2. Best for 3D Modeling (Replacing AutoCAD 3D) FreeCAD
Type: Open-source, parametric. Strengths: Designed for real-world objects (mechanical engineering, product design). You can go back and change parameters (like a hole’s diameter) and the model updates automatically. Limitations: Steep learning curve. UI is less polished than AutoCAD. Best if: You need parametric, precision 3D modeling for engineering or 3D printing.
Blender
Type: Open-source, free. Strengths: Extremely powerful for organic shapes, rendering, animation, and architectural visualization. Huge community support. Limitations: Not a traditional CAD tool (no parametric constraints, no standard drafting workflow). Best if: You need 3D renders, animations, or game assets, not technical manufacturing drawings.
3. Best for Architecture & BIM BricsCAD Shape
