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。以此草图创建的零件设计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。
How to use
- Select the face of a PartDesign feature or a solid.
- Click on the Map sketch to face icon in the toolbar (or go to the PartDesign or Sketch menu depending on which workbench is active)
- In the Select sketch dialog window that opens, select from the list the sketch to map to the face and click OK.
- The sketch is automatically opened in edit mode.
Use when repairing a broken model
Sketcher MapSketch is often used when repairing a broken model.
One common use case is when the dependency graph has been broken. (You can view the dependency graph by Tools → Dependency graph.) This can happen when you delete a feature in the middle of your model tree. In the following example we will break and repair a model.
This is the base model. It has one pad, a pocket, and a pad inside that pocket. Note that the dependency graph is linear.
Now we have deleted the pocket and the sketch that created the pocket (Pocket and Sketch001). Note that the dependency graph is broken. To repair this model we want to attach Sketch002 to the top face of Pad. In the view of the model you can see that it would be easy to select the wrong face.
To repair the model we first change the visibility of the solids. We make Pad001 hidden and we make Pad visible.
Now we select the top face of Pad and then select the Map A Sketch To A Face tool. In the dialog that appears we select Sketch002. Our model is now repaired. In the model view we make Pad001 visible and Pad hidden and we can see the correct model.
