AutoCAD Skills v1.1.0 - GB/T Anchors and Tiered Verification
Why this release
This release hardens the skill for real Agent/MCP deployment: stronger GB/T anchoring, lower verification cost for safe local edits, and deterministic DRC coverage for standard mechanical representations.
本版本针对实际部署中的三个痛点:国外底座模型容易默认第三角画法;轻量修改被完整导出/重导流程拖慢;螺纹和标准件常被画成“看起来像、但不符合 GB/T”的几何。
Changes
- Default to first-angle projection for GB/T work only when the user, source drawing, and approved template do not specify another method; cross-check view placement, projection symbol, and title-block declaration.
- Add Chinese technical-lettering checks for glyph coverage, proportion, substitution, text bounds, and final PDF output. Font filenames such as
gbenor/gbcbigare implementation choices, not automatic compliance. - Add verified current standards for springs, centre holes, and rolling bearings: GB/T 4459.4-2003, GB/T 4459.5-1999, and GB/T 4459.7-2017.
- Add release DRC rule IDs for projection, title block, Chinese text, threads, gears, splines, springs, centre holes, and rolling bearings.
- Enforce GB/T simplified 2D representations instead of projecting full helical threads, all gear/spline teeth, spring turns, or rolling elements into routine views.
- Introduce three verification tiers: Tier 1 local fast path, Tier 2 affected-system verification, and Tier 3 full release verification.
- Tier 1 proves targeted parameter/handle/geometry and affected-view changes without forcing an unchanged PDF/DXF/STEP loop.
- Add escalation triggers for units, datums, projection, configuration, topology mapping, cross-view authority, BOM, dependencies, schemas, and release-critical changes.
- Prefer scoped in-place repair for isolated defects; reserve clean replacement geometry for widespread or authority/topology failures.
- Extend DRC reports with
verification_tierand explicit deferred gates/escalation triggers.
Validation
- Skill structure: valid
- Obsolete unconditional export/re-import requirements: removed
- Official standard metadata checked on the Chinese national standards platform
Manufacturing artifacts remain candidate after human review unless an authorized external process approves the exact revision and configuration.
