Downloads the latest copy of the document from the managed library and locks the document in the library so that other users cannot make modifications. Any parts or subassemblies which may have been added to the subassembly out of context are downloaded to cache to ensure the structure and properties of the active document are up-to-date. The Check Out command also changes the document status in the local cache to read-write, so you can make changes to the document. If you check the document out of a Teamcenter-managed environment, the Select Revision Rule dialog box displays so you can choose which revision rule is used. If you check out a direct document, the associated linked indirect documents are downloaded to your local cache and use the revision rule specified. If you in-place activate a part in an assembly, the part is checked out.

Managed direct documents opened with read-only permissions can be checked out using the Check Out command. The command verifies the active document is the most recent version, checks the file out of the library, sets the file to a writable state, and enables the Save command for you to save any in-memory file changes. This command is available in Insight and Teamcenter environments for Assembly (.asm), Part (.par), Sheet Metal (.psm), Draft (.dft), View and Markup, and Revision Manager.
