WHAT IT DOES

What sw_close_document does on Solidworks

WHY IT NEEDS A POLICY

Why sw_close_document needs a policy

Closing a document is a state-modifying action that affects the SolidWorks application and potentially unsaved work, but it is reversible (the document can be reopened). This is not destructive deletion of the underlying file, nor is it a read operation. The severity is medium because misuse could cause loss of unsaved work, but the document itself remains intact on disk.

From the tool's definition Tool name 'sw_close_document' and description '关闭指定路径的文档或当前活动文档' (close document at specified path or current active document) indicate the tool modifies application state by closing open documents.
