## 基础类型 (`vde::core`)

```cpp
// 3D 点
Point3D p(1.0, 2.0, 3.0);
double x = p.x(), y = p.y(), z = p.z();

// 3D 向量
Vector3D v = p2 - p1;
double len = v.norm();
Vector3D n = v.normalized();
double dot = a.dot(b);
Vector3D cross = a.cross(b);

// 包围盒
AABB3D box(p_min, p_max);
box.expand(point);
bool hit = box.intersects(other);
auto center = box.center();
```

## B-Rep 建模 (`vde::brep`)

```cpp
// 创建
auto box = make_box(2, 3, 4);
auto cyl = make_cylinder(1.5, 6, 32);
auto sphere = make_sphere(2, 32, 16);

// 布尔
auto result = brep_union(a, b);
auto result = brep_intersection(a, b);
auto result = brep_difference(a, b);

// 修复
heal_topology(body);
auto report = validate(body);  // ValidationReport

// 直接建模
push_pull(body, face_id, 5.0);
tweak_face(body, face_id, 2.0);

// 转换
auto mesh = body.to_mesh(0.01);  // HalfedgeMesh
auto bb = body.bounds();          // AABB3D
size_t n = body.num_faces();
const auto& f = body.face(id);
```

## 曲线曲面 (`vde::curves`)

```cpp
// 求值
Point3D p = surf.evaluate(u, v);
Vector3D n = surf.normal(u, v);

// 分析
auto cmap = curvature_map(surf, 64, 64);
auto cont = surface_continuity(a, b, edge);

// 生成
auto swept = sweep_surface(profile, path);
auto lofted = loft_surface(sections);
auto netted = net_surface(u_curves, v_curves);
```

## 网格 (`vde::mesh`)

```cpp
// 简化
auto simplified = simplify_mesh(mesh, 0.5);

// MC
auto mesh = marching_cubes(sdf, bounds, 64);

// FEA
auto tets = tetrahedral_mesh(body, TetraParams{});
auto hex = mapped_hex_mesh(body, src, tgt);
```

## 格式 IO (`vde::foundation`)

```cpp
// STEP
auto body = import_step_file("input.step");
export_step_file(body, "output.step");

// IGES
auto body = import_iges_file("input.igs");

// 工业格式
auto body = import_parasolid_xt("model.x_t");
auto body = import_acis_sat("model.sat");
auto body = import_jt("model.jt");
```

## CAM (`vde::core`)

```cpp
Tool tool{ToolType::ENDMILL, 10.0, 4, 50.0};

auto rough = roughing_toolpath(body, tool, {});
auto finish = finishing_toolpath(body, tool, {});
auto drill = drilling_toolpath(points, tool, {5, 10});

FanucPost post;
auto gcode = post.generate(toolpath);
```
