Hard-surface modeling
Inspect the scene, units, capability details, and supplied dimensions before mutation. Preserve separate functional parts and an editable modifier order. Prefer Mirror/Array for repetition, Boolean for openings, Bevel for manufactured edges, Solidify for sheet thickness, and Subdivision only when the intended silhouette needs it.
Use recipe.hard_surface_shell or recipe.spear when its declared output matches the task. Otherwise combine registered object, mesh, modifier, curve, and collection commands. Never use expert Python to claim missing hard-surface coverage.
After topology changes, discard old mesh selections and query a new topology version. Inspect designated solids with mesh.inspect; explicitly set allowOpenSurface only for intentionally open surfaces. Check dimensions, modifier order, helper visibility, normals, degenerate geometry, and whether requested parts remain independently editable. L2 recipe output is not L3 until a saved, reopened, visually reviewed and reimported deliverable passes.
If a required asset, exact dimension, unsupported modifier parameter, or extension is missing, report it. Only invent a proxy when the task already authorizes original design, and list that proxy in delivery.
什么时候使用(When to Use)
创建产品、机械件、道具、外壳、开孔和可编辑重复结构时使用;需要有机雕刻时改用表面雕刻技能。
输入与前置条件(Prerequisites)
- 明确单位、关键尺寸、公差、功能分件、对称/阵列规则和参考素材授权。
- 记录允许的 modifier、开放表面意图和必须保持独立编辑的部件。
执行流程(Workflow)
Step 1. 检查比例与命名,按功能拆分对象和集合。 Step 2. 先完成主轮廓,再按意图添加 Mirror、Array、Boolean、Bevel、Solidify。 Step 3. 保持可解释 modifier 顺序,拓扑改变后重新查询选择与版本。 Step 4. 检查尺寸、法线、退化几何、helper 可见性和独立编辑性。 Step 5. 保存重开并从交付相机审阅制造边缘与轮廓。
验证与交付证据(Validation)
提交实际尺寸、对象/集合清单、modifier 顺序、mesh.inspect 结果、开放表面声明、预览和重开证据。
Rules 与能力边界(不适用场景)
不以 expert Python 冒充缺失能力,不下载未授权资产,不把简单夹具通过当成所有格式或生产制造验证。
Gotchas(常见问题与恢复)
- Boolean 破面:检查应用 scale、相交体和求解器,不堆叠重复 Boolean。
- Bevel 不均匀:先处理对象 scale 与法线。
- 尺寸漂移:回到参数和基准面,禁止用视觉缩放代替精确值。
