# tangency-labs/solidcraft

> An open-source parametric 3D CAD written in pure Rust, a clean-room reimplementation of Autodesk Fusion 360, with sketch constraints, a feature timeline, and export to STEP/IGES/STL. Runs as a desktop app, in the browser, or headless via CLI, and can be driven by AI agents over MCP.

## Useful for

- Model a parametric part as a JSON command script and export it to STEP from the CLI
- Let an AI agent sketch, extrude and measure a part through the built-in MCP server
- Import an existing STEP file, measure its volume and area, then build new features on it

## Why it’s here

- Star-counter measurements on 2026-10-16 (UTC), 00:04–18:02: 2720 → 3022 stars (+302). This is the change over that interval.
- Estimated end-of-day forecast: about +393 stars, using observed gains and the previous day.
- The repository is 9 days old and already has 3,022 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Top new repositories this month: #48.
- Hacker News: “Show HN: SolidCraft – Open-Source Parametric CAD in Rust (With MCP Support)” — 141 points, 3 days ago.
- About 60 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 328
- Issues and pull requests: 1,771
- Watchers: 30
- Average over the last week: 453 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 11
- Latest release: v0.14.0 (2026-10-16)

## Stars per day, last 10 days (oldest → newest, today is partial)

2026-10-07 … 2026-10-16: 0, 0, 46, 99, 568, 500, 735, 550, 325, 302

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
