Hackerscad

Hackerscad: Parametric computer-aided design software generates three-dimensional models from code and mouse interactions.

Hackerscad is a parametric computer-aided design application where the model is defined as code. Users type to update the three-dimensional view or use the mouse to edit features like fillets and holes, which automatically writes readable code into the file. It supports exact solids, real threads, and exports files such as 3MF with color per part, STL, STEP, and drawings with views and dimensions. A sandboxed language handles units, selectors, and libraries, allowing models to be versioned and reviewed like standard code. Built-in unittest blocks verify part requirements through the command line or CI scripts. An MCP server and agent skill let AI assistants model parts, check sizes, and render designs directly.
