描述
草图验证(Validate sketch)工具可用于修复不可编辑的草图、存在无效约束的草图,以及添加有缺失的重合约束的根据DXF等文件中导入的几何图形所创建的草图。此工具也可有效的定位本地草图中缺失的重合约束,这个问题将导致在您试图应用一个PartDesign特征时生成一个"can't validate broken face"错误。
如何使用
- Select the sketch to validate, either from the Model tree, or by clicking on one of its edges in the 3D view. Note: the sketch must not be in editing mode. If you are in sketch edit mode, you need to exit the sketch.
- Open the validate sketch utility from the Sketch or Part Design menu.
- See Options below for operation.
- Press the Close button when done.
选项
Missing coincidences
Finds out missing coincidences for overlapping vertices, and adds them. Press the Find button; a pop up dialog will appear to report how many missing coincidences were found; they will be shown in the 3D view as yellow crosses. Press OK to close the dialog, then press the Fix button to add the missing coincidences.
If necessary, define a larger tolerance value in the drop-down field.
Leave the "Ignore construction geometry" checkbox checked to disregard construction geometry in the analysis.
