使用SOLIDWORKS API替换组件并保留选择

{ width=350 }

该宏允许使用SOLIDWORKS API将树中选择的组件替换为指定文件夹中的组件（可选地带有附加后缀的名称）。

在管理类似类型的项目时，此功能可能非常有用，其中某些文件被复制、更新和重命名，并且需要在原始装配中进行替换。

该宏使用了SOLIDWORKS API中的仅API选择，它允许保留原始选择的组件，并避免使用临时集合变量来满足SOLIDWORKS API方法IAssemblyDoc::ReplaceComponents2的要求，该方法要求为每个组件选择替换。

• 修改输入参数。通过REPLACEMENT_DIR设置替换零件所在的目录，并可选地使用SUFFIX设置文件名的后缀。

Const REPLACEMENT_DIR As String = "D:\Assembly\Replacement"
Const SUFFIX As String = "_new"

• 选择组件
• 运行宏。所有组件都将被替换

Const REPLACEMENT_DIR As String = "D:\Assembly\Replacement"
Const SUFFIX As String = "_new"
