SolveSpace is a free, open-source parametric CAD tool that combines 3D modeling, 2D drafting, and mechanical simulation in a compact, efficient package. Designed for engineers, designers, and hobbyists who need precision and control without the bloat, SolveSpace offers constraint-based modeling, solid modeling, and CAM support—all in a lightweight application. It’s ideal for quick prototyping, mechanical design, and educational use.

- Parametric Modeling: Use constraints to define geometry precisely and make updates dynamically as parameters change.

- 3D Solid Modeling: Create extrusions, revolves, Boolean operations, and assemblies with constraint-driven accuracy.

- 2D Drafting & Sketching: Create detailed 2D drawings and export to DXF, SVG, or PDF for laser cutting, documentation, or CNC.

- CAM & CNC Support: Generate G-code directly for 2.5D CAM operations like milling or cutting.

- Mechanical Simulation: Test linkages and assemblies for range of motion and mechanical behavior.

- File Import/Export: Supports STL, STEP, DXF, SVG, PDF, and more for interoperability with other CAD and fabrication tools.

- Lightweight & Portable: Small download size, fast performance, and runs on modest hardware or from a USB stick.

- Free and Open-Source: No licenses or subscriptions—full access for personal, educational, or commercial use.

SolveSpace is perfect for engineers, makers, CNC users, educators, and hobbyists who need a nimble, efficient CAD tool for mechanical design, prototyping, and fabrication. It’s especially valuable for users who prefer open-source solutions and parametric workflows.

SolveSpace delivers powerful parametric CAD features in a minimal, open-source package. With robust modeling tools, CAM
