SolveSpace
Parametric 2D and 3D CAD tool with constraint solving and a command-line interface.
GPL-3.0-or-later, Windows, macOS and Linux
SolveSpace is a parametric 2D/3D CAD tool. It suits makers and engineers who draw mechanical parts with dimension constraints.
What it is
The README lists GUI versions in GTK 3, GTK 4 and Qt 6 on Linux, a graphical app on Windows and macOS, a command-line interface, and an experimental Emscripten web build with many known critical bugs.
Who it's for
It suits mechanical designers who want a small constraint-based CAD tool. It does not suit anyone who needs architectural modelling libraries, since it is a parametric part modeller.

Our honest verdict
What's great
- Release packages for Windows and macOS, Flatpak and Snap for Linux.
- Nightly archives let you try new work.
- GPL v3 or later.
- Source builds need only git, CMake and a C++ compiler.
Where it falls short
- The web build is experimental with many known critical bugs and no CLI.
- 64-bit Windows edge builds do not support 6DOF controllers like SpaceMouse.
- The README lists no architectural or rendering features.
