dsh-cad — CAD Plugin for DeepSeek Harness

English | 简体中文

A CAD plugin for DeepSeek Harness (dsh): an embedded 3D/2D CAD viewer plus a native parametric modeling tool family (OCCT kernel) in the Web UI, letting the agent build and inspect CAD geometry step by step — "model while you watch". Preview

A full modeling session, end to end: the agent builds a parametric assembly from plain chat — a 120×80×8 base plate with R5 rounded corners, then four bolt instances placed at the corners — while the resident CAD panel tracks every step live (parts tree with per-instance colors, ViewCube, "装配体" assembly tab, 5 instances · 1,740 triangles). The finished assembly exports as a structured STEP document and the agent verifies it by reading the file back — 2 solids, 3 products, 2 assembly usages, 1,125.00 mm³:

Feature Overview Installation

The plugin is published to npm — one line:

The installer applies the bundled cordis.patch.yml (declared in the dsh.bundle manifest) automatically, so there is nothing to configure by hand. Version requirements Node.js and dsh CLI (@deepseek-ai/dsh): minimum versions live in the badge row above and the engines field of package.json — kept out of the prose so they never go stale Install from source (dev mode)

The patch insert ships as cordis.patch.yml in the package root and is applied by the installer via the same dsh.bundle manifest.
