一个常见的用例是所依赖的关系图(graph)有所损坏。(您可以通过{{MenuCommand|Tools → Dependency graph}}来查阅依赖关系图。)从模型树中间删除某个特征可能是造成这个问题的罪魁祸首。在以下示例中,我们将实际破坏并修复一个模型。 |

这是一个基础模型。其中有一个凸垫,一个凹槽,以及一个凹槽中凸垫。请注意,此模型的依赖图是线性的。 |

我们现在已删除了凹槽以及凹槽所创建的草图(即Pocket与Sketch001)。注意到,依赖图一分为二,坏掉了。为了修复此模型,我们希望将Sketch002附于Pad的顶面上。在此模型的视图中,您将发现很容易选错面。 |

为了修复此模型,我们首先改变此实体的可见性。即隐藏Pad001并令Pad可见。 |
|||
[[File:JschremppFCADEdit3.png]] |
|||
我们现在选择Pad的顶面,再选择草图映射工具。在弹出的对话框中选中Sketch002。此时,我们的模型就修复好了。在模型视图中,我们令Pad001可见,并隐藏Pad,即可看到正确的模型。 |

Description
描述
此工具会将一个存在的草图映射至一个几何图形的面上。以此草图创建的PartDesign特征可针对相加特征(如两种挤出成型方式Pad与evolution)与基础实体融合,或针对相减特征(如两种挖槽方式Pocket与Groove)与基础实体相减。
请注意,此工具不能用于创建新的草图。仅限于进行草图映射,或将存在的草图重新映射至实体面或PartDesign特征。典型的使用场景:
- 草图被创建在一个标准的平面上(XY, XZ, YZ),而您却想将其映射至一个实体面上,从而进一步在此构建一个特征。
- 草图被映射至实体的某个特定面上,而您却需要把它映射至另一个不同的面上。
- 修复一个坏掉的模型。
Usage
如何使用
- 选择一个PartDesign特征上的面或一个实体上的面。
- 点击工具栏中的 Map sketch to face图标(或前往当前所用工作台中的PartDesign或Sketch菜单找此工具)。
- 在打开的Select sketch对话窗口中的列表里选择待映射至面上的草图,并点击OK。
- 草图将自动在编辑模式下打开。
