打开活动文档或选定组件的关联图纸

这个VBA宏允许打开装配体中选定组件的关联图纸，或者如果没有选定任何内容，则打开活动文档。

与开箱即用的功能不同，此宏没有与组件同名并位于同一文件夹中的图纸的限制。此宏将在当前文件夹（活动文档的文件夹）的所有子文件夹中查找所有图纸，无论这些图纸是否以组件命名。

此宏有一个选项，可以以解析或详图模式打开图纸。修改 OPEN_DRAWING_DETAILING 的值以更改行为。

Const OPEN_DRAWING_DETAILING As Boolean = True '以详图模式打开图纸

Const OPEN_DRAWING_DETAILING As Boolean = False
