LibreCAD
★★★★☆A free, open-source 2D CAD application built for creating precise technical drawings. LibreCAD is a great alternative for users who primarily work with 2D drafting and do not need full 3D modeling capabilities. Its interface will feel familiar to anyone who has used AutoCAD's 2D environment.
Features
- Full-featured 2D drafting and design tools
- DXF and DWG file format compatibility
- Layer management with customizable properties
- Comprehensive snapping and dimensioning tools
- Block library for reusable components
- Command-line interface for precise input
Install
OpenSCAD
★★★★☆A unique, script-based 3D CAD modeler where models are created by writing code rather than interactive manipulation. OpenSCAD is ideal for engineers and makers who prefer a programmatic approach to design, and it excels at creating precise, parametric parts for 3D printing.
Features
- Script-based modeling using its own description language
- CSG (Constructive Solid Geometry) and extrusion operations
- Parametric designs with variables and functions
- STL and OFF export for 3D printing
- Customizer interface for adjusting parameters visually
- Cross-platform with consistent behavior
