index

{ width=600 }

这个VBA宏允许自动为SOLIDWORKS装配中选定的组件引用分配数字编号。

编号根据指定的种子值自动递增。

编号按照组件在装配中的选择顺序进行分配。

组件可以在特征管理器树或图形区域中选择（可以选择组件的任何实体，例如面或边）。

宏可以配置为在弹出框中指定输入（将INPUT_SEED变量的值设置为True），或者通过提供种子作为常量来指定输入（INPUT_SEED等于False，SEED等于种子编号）。

Const INPUT_SEED As Boolean = True '在运行宏时在输入框中输入种子（起始）编号
Const SEED As Integer = 1

Enum ScopeType_e
    Selected
    topLevel
    All
End Enum

Const SCOPE As Integer = ScopeType_e.Selected
Const INPUT_SEED As Boolean = False
Const SEED As Integer = 1
