gitcad 0.7.7

Agent-first, headless, git-native CAD (metapackage: core + mech + ecad + MCP + viewer + release)

gitcad

Agent-first, headless, git-native CAD — mechanical and electrical, one substrate.

gitcad is a boundary-representation CAD system designed to be driven by agents and version-controlled like source. Models are byte-canonical text (geometry is a build artifact, never committed); identity is construction-lineage based, never ordinal; every build produces a reviewable, diffable report.

This metapackage installs the whole system:

package	domain
gitcad-core	canonical text, stable identity, the Part standard, report pipeline
gitcad-mech	document model, exact B-rep kernel, sketches, drawings, importers
gitcad-ecad	schematic + ERC, board + DRC, fab outputs, KiCad import

Install

pip install gitcad           # full system: both domains, exact+native kernel, MCP server
pip install gitcad[occt]     # + OCCT kernel oracle/fallback (cadquery-ocp)

pip install gitcad is complete and agent-ready out of the box — mechanical and electrical, the exact kernel with its native accelerator, and the gitcad-mcp Model Context Protocol server. Only OCCT (a heavy optional oracle) is an extra.

The mechanical kernel is exact: topological decisions are made in rational arithmetic (ℚ), never by a floating-point tolerance — see forgekernel and the benchmarks vs OCCT. The compiled Rust build of the hot paths installs by default on mainstream platforms (identical results, only faster); on an architecture with no wheel it is skipped and the kernel runs pure-Python — same answers, nothing breaks.
