Adds production-grade engineering features and tools: 2D GD&T (feature control frames + datum features) via engineering/gdt.py, ISO‑129 dimension tolerance support (engineering/tolerances.py) and an ezdxf/COM plumbing for toleranced dims, a scalar drawing score + invalidity ratio (engineering/scoring.py) wired into drawing_finalize, in-place entity editors (entity_edit_text/entity_edit_geometry), and a friendly drawing_settings facade. Includes server tool wiring, COM/ezdxf backend implementations, datum-consistency critique, many unit tests, README/CLAUDE/CHANGELOG updates, and a version bump to 1.2.0. Also corrects COM backend capability label (entities_2d).

## [Unreleased]
|
|
|
|
_Next: closed-loop refiner (critique→repair→re-critique with transaction-stack isolation), pre-plan clarification pass, ISO 286 fit-table lookup (H7/g6 → deviations), and a local-VLM visual judge._
|
|
|
|
## [1.2.0] — 2026-07-07
|
|
|
|
Production-ISO parity + a measurable quality moat. **360 tests, ruff-clean.** Tool count: 111 → 116.
|
|
|
|
### Added
|
|
- **`drawing_settings`** — read or change common AutoCAD drawing settings by
|
|
friendly name (units mm/cm/m/inch/feet, linear/angular precision, LTSCALE,
|
|
DIMSCALE, text size, point mode/size, OSMODE, fillet radius) without
|
|
memorising system-variable names. Call with no argument for a full snapshot.
|
|
A convenience facade over `system_get_variable` / `system_set_variable`;
|
|
cross-backend.
|
|
- **In-place editing** — `entity_edit_text` re-labels or resizes an existing
|
|
TEXT/MTEXT entity, and `entity_edit_geometry` re-drives a CIRCLE/LINE/ARC
|
|
(center, radius, endpoints, arc angles) — both **preserve the entity handle**,
|
|
so the user can adjust a drawing without delete-and-recreate. Cross-backend.
|
|
- **2D GD&T (ISO 1101 / ASME Y14.5)** — `gd_frame` draws a feature control frame
|
|
(all 14 geometric characteristics, ⌀ zone prefix, Ⓜ/Ⓛ/Ⓢ material modifiers,
|
|
multi-datum references) and `datum_feature` places a datum symbol. Frames are
|
|
composed from LINE + TEXT so they render identically on **both** the COM and
|
|
ezdxf backends (ezdxf's native TOLERANCE entity renders blank via matplotlib).
|
|
No competing CAD MCP or surveyed text-to-CAD product ships 2D GD&T authoring.
|
|
- **GD&T datum-consistency gate** — a new `gdt` critique focus fails
|
|
`drawing_finalize` when a feature control frame references a datum with no
|
|
matching datum feature (a meaningless FCF per ISO 1101).
|
|
- **ISO 129 dimension tolerances** — `dimension_linear` / `dimension_radius` /
|
|
`dimension_diameter` gain `tol_upper` / `tol_lower` / `tol_mode`
|
|
(`symmetric` ±, `deviation` +a/-b, `limit` stacked, `basic` boxed) and a
|
|
`text_override` (e.g. `⌀20 H7`). Toleranced production dimensions are now
|
|
possible — previously the single biggest functional gap.
|
|
- **Scalar drawing-score + invalidity ratio** (`engineering/scoring.py`) — the
|
|
`drawing_finalize` payload now carries a 0-100 `score`, an `invalidity_ratio`,
|
|
and an A-F `grade` over the union of the structural validator and the premium
|
|
critique, so drawing quality is regression-trackable (MUSE / CadBench grade an
|
|
Invalidity Ratio, not shape).
|
|
|
|
### Fixed
|
|
- **Honesty**: the COM backend advertised a false `all_entity_types` capability
|
|
(it authors 2D entities only, no 3D solids) — corrected to `entities_2d`.
|
|
|
|
## [1.1.1] — 2026-06-20
|
|
|
|
### Added
|
|
- **`selection_get`** (Entity Query, COM backend): reads AutoCAD's implied
|
|
("pickfirst") viewport selection — the entities the user highlighted with
|
|
grips before invoking the AI — and returns their handles + `EntityInfo`.
|
|
This lets the AI scope work to exactly what the user picked
|
|
(`dimension_auto(selection_get()["handles"])`) instead of acting on the whole
|
|
drawing. Resolves [#1](https://github.com/U-C4N/Autocad-MCP/issues/1) — the
|
|
layer-juggling workaround is no longer needed. Surfaces the `PICKFIRST` sysvar
|
|
state so an empty selection is self-explanatory. The ezdxf headless backend
|
|
has no viewport, so it returns `ok=False` with an empty handle list (same
|
|
shape, never raises). Tool count: 110 → 111.
|
|
|
|
## [1.1.0] — 2026-06-19
|
|
|
|
Correctness, cross-backend parity, and an **enforced** quality gate, landed across four audited
|
|
sprints (see `docs/analysis/`). 318 tests, ruff-clean.
|
|
|
|
### Added
|
|
- **Premium drafting workflow** (shared across both backends): `drawing_plan`, `drawing_critique`
|
|
(ISO-128 focuses), `point_from_snap`, `drawing_apply_iso_layers`, `dimension_auto`,
|
|
`entity_select_smart`, `construction_xline` / `construction_clear`.
|
|
- **Deterministic geometry** for exact OSNAP coordinates: `point_intersection`
|
|
(line/line, line/circle, circle/circle) and `point_tangent` (external point → circle).
|
|
- **Engineering / deterministic CAD layer**: involute gear front view + section A-A,
|
|
DIN 6885 keyed bore, ISO A3 title block, and the 8-step `drawing_finalize` validator.
|
|
- **HTTP bearer-token auth**: `StaticTokenVerifier` wired into FastMCP when `MCP_AUTH_TOKEN` is set.
|
|
- Mocked-COM test harness (`tests/test_com_backend.py` + Sprint-3/4 suites) — COM logic is now
|
|
regression-tested on Linux CI without a live AutoCAD.
|
|
- `entity_create_mtext` rotation parameter; `dimension_auto` layer override; `bounding_box` /
|
|
ARC `length` / TEXT-MTEXT `rotation`+`char_height` on both backends; `BlockInfo.description`.
|
|
- Security module (`security.py`), centralized config (`config.py`), `.env.example`, path
|
|
validation, command/LISP sanitization, ruff config, pre-commit hooks, pytest-cov.
|
|
|
|
### Changed
|
|
- **`drawing_finalize` now enforces the premium critique** in addition to the structural validator:
|
|
leftover construction geometry, non-ISO-128 lineweights, untrimmed corners, duplicate entities,
|
|
and dimension overlap block the gate (was advisory-only). `strict_critique=True` fails on warnings too.
|
|
- **`drawing_save_as` derives the on-disk format from the file extension** — `part.dxf` writes DXF,
|
|
not DWG. ezdxf refuses to mislabel a `.dwg` file.
|
|
- Dimension and construction layers resolve from the active layer set (iso13567 → `M-DIMEN-T-N` /
|
|
`M-CONST-E-N`, not the hardcoded `DIM` / `CONSTRUCTION`).
|
|
- Premium meta-tools lifted into the shared `AutoCADBackend` base class (single source of truth).
|
|
- Dead code removed (`section.py`, `generate_tooth_profile`, `CommandResult`, `set_layer_active`, …).
|
|
|
|
### Fixed
|
|
- ezdxf `dimension_aligned` / `dimension_angular` raised `TypeError` (wrong ezdxf 1.4 args) — fixed.
|
|
- Full-circle polar array placed a duplicate copy over the original — fixed (divisor = count).
|
|
- `entity_offset` ignored `side_x`/`side_y` on both backends — now honored (and COM no longer leaks extras).
|
|
- COM `entity_create_hatch` built an associative hatch then deleted its boundary — now non-associative.
|
|
- Lineweight mm-vs-hundredths truncation wiped ISO-128 weights — fixed via `normalize_lineweight`.
|
|
- **`view_screenshot` / `drawing_export_pdf` could SIGSEGV** (matplotlib GUI backend in a worker thread)
|
|
— now render headless via `Agg` (`Figure` + `FigureCanvasAgg`).
|
|
- `entity_select_smart` `length_range` silently rejected all ARCs (no `length`) — fixed.
|
|
- Gear tooth profile self-overlapped for high tooth counts (z ≥ ~42); section view drew duplicate
|
|
bore lines; validator keyway heuristic was a permanent false-negative — all fixed.
|
|
- COM `system_run_lisp` always reported `"nil"`; `system_set_variable` didn't coerce numeric sysvars
|
|
— fixed. `system_about` tool groups / `_registered_tool_count` no longer drift or surface `-1`.
|
|
- `drawing_new` bootstrap failures now surface as `degraded` instead of reporting success.
|
|
|
|
### Security
|
|
- HTTP remote-bind guard now fires on **every** launch path (including `fastmcp run server.py:mcp`),
|
|
not only the `__main__` block — closing an anonymous-remote-bind gap.
|
|
- AutoLISP allowlist bypass-vector regression tests (newline injection, symbol aliasing, `vla*`/`acet-*`,
|
|
`c:` custom commands).
|
|
- COM apartment leak bounded (`CoUninitialize` on teardown); transaction commit/rollback and
|
|
`system_run_lisp` now respect the CMDACTIVE guard.
|
|
|
|
