处理
在“提取”模式下具有新提取的几何图形零件的特征或在“删除”模式下移除选定零件的原始特征。
Untouched
Features that were not modified by the transformer.
参数
Geometry Part Selection
Geometry XQuery
如果要仅隔离传递到变换器的几何图形的一部分，请使用此参数。如果未指定任何条件，则操作将应用于所有级别的整个几何图形。
Selection can be based on structural location, geometry name, type, appearance information, traits, trait storage types, or definition reference. The syntax used is a restricted set of XQuery, where the return clause is fixed.
“基本几何体XQuery”对话框允许您通过基于指定的测试子句自动编写必要的查询来构造简单的选择查询。单击SwitchtoAdvanced按钮打开AdvancedEditor，它允许您自由键入查询，以获得更具表现力的查询。
Note:Once you switch to Advanced mode, you will have to clear all parameters before you can return to Basic mode.
层次几何体表示为类型几何体的节点，属性包含有关每个几何体的特征、类型和名称的信息。
Note:
参数
Action
- 提取：将选定的几何图形零件提取到新特征中
- Remove: Remove selected geometry parts from original feature and return pruned result
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click
