Trimming an Object

使用 Intersect with Model 裁剪物体。

Cutting All Intersected Objects

一次性裁剪多个物体。

Using Groups or Components to Create Cutting Objects

下图中,有两种样式的裁剪:

  a) 实体模型

  b) 壳状模型

Google SketchUp Cookbook: (Chapter 3) Intersection Edges: Cutting and Trimming-LMLPHP

实体模型:裁剪后,保留了裁剪物体的部分表面,与被裁剪物体结合在一起

壳状模型:裁剪后,将裁剪物体完全删除掉了

Intersecting with Groups and Components, Without Exploding

Google SketchUp Cookbook: (Chapter 3) Intersection Edges: Cutting and Trimming-LMLPHP

上图是 Building with Glass Windows,Building 处于 Exploded 状态(既不是 Group,也不是 Component),Glass Window 是组件(Component)

在 Building 上生成 Intersection edges:选中 Building 所有几何元素 -> 右键菜单 -> Intersect Faces -> with Model

在 Glass Window 上生成 Intersection edges:选中并编辑 Glass Window 组件 -> 选中 Glass Window 所有几何元素 -> 右键菜单 -> Intersect Faces -> with Model

Intersecting with Both Intact and Exploded Components

这个例子是说,有一个双层抽屉,抽屉上有4个把手,把手创建为组件,先用把手作为裁剪物体去裁剪抽屉正面,在抽屉正面钻出用于安装把手的小洞。

同时把手组件上保留有 Intersection edges,最后将把手组件放回抽屉正面。

Intersecting Only Selected Objects

这个容易理解,仅在选中的物体上生成 intersection edges。

这里有一个快速选择几何元素的技巧,根据材质选择

  a) 先选择一个面

  b) 右键菜单 -> Select -> All with same Material

Intersecting Within a Group or Component

Intersect Faces -> with Context

当你需要在一个组或组件内部产生 intersection edges ,并且不受模型其余部分的影响时,请使用 Intersect Faces with Context

Using Intersect to Trim Components with Themselves

组件与组件之间相交,用圆木堆砌小围栏,见下图效果。
