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.

Key Features:

• 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.

Who Should Use It?

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.

Summary:

SolveSpace delivers powerful parametric CAD features in a minimal, open-source package. With robust modeling tools, CAM support, and mechanical simulation, it’s a versatile tool for creators who need precision and performance without complexity or cost.
