## Health v2 (maintenance only)
Score: 80/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 99, release rhythm 45, longevity 100
- inputs: {"age_days": 4178, "days_push": 7, "days_rel": 159, "gap_med": null, "n_releases_24m": 1}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
SolveSpace is a free, open-source parametric 2D/3D CAD application with a constraint-based sketcher and solid modeling via extrudes, revolves, and Boolean operations. It supports exporting STL, STEP, DXF, PDF, and SVG for 3D printing, CAM, and 2D part workflows.

## Use cases
- model 3d parts for 3d printing
- export stl files for a 3d printer
- draw 2d parts and export dxf or svg
- prepare cam data for laser cutting or waterjet
- design and simulate planar linkages and mechanisms
- solve geometry problems with a live dimensioned drawing
- create parametric assemblies of linked parts

## When to choose
- you need a lightweight, free parametric CAD tool for mechanical parts
- you want constraint-driven sketching with a built-in geometric solver
- you need STL/STEP/DXF export for 3D printing or CAM workflows
- you run Windows, macOS, or Linux and want an installable desktop CAD app

## When to avoid
- you need advanced surface modeling, fillets, or large assemblies found in commercial CAD
- you require DWG compatibility or industry-standard drawing documentation
- you need a cloud or browser-only CAD workflow (though a limited web version exists)

## Facets
- artifact type: application
- maturity: active
- function: simulation, graphics, gui, sdk
- domain: computer-vision, graphics, developer-tools, cross-platform
- platform: windows, cross-platform, cpp
- tags: cad, parametric-modeling, 3d-printing, constraint-solver, mechanism-design, cam, stl-export, step-export, macos, linux
