Within an individual blueprint course, you can lock and unlock course objects and sync content for the blueprint course. If you are not sure how objects were defined for the course, you can view them in the Course Settings Course Details tab. Attributes for locked objects may be changed in Course Settings at any time.
If you enroll an instructor in a blueprint course, the instructor can also lock and unlock course objects. By default, objects in blueprint courses are unlocked.
Locked Objects
Locking an object in a course enforces the attributes defined in Course Settings. Any change to an attribute retroactively applies to all locked objects in the associated course. If an attribute is enabled for locked objects in the blueprint course, any locked attributes in the associated course that vary from locked attributes in the blueprint course will trigger unsynced changes in the blueprint course and override the associated course objects.
Locking or unlocking an object applies immediately to all associated courses. However, the change will still be noted as an unsynced change and will not appear in the Sync History page until the sync is complete. Additionally, changes are not identified as an unsynced change until the page is refreshed.
Unlocked Objects
Objects that are unlocked can be managed by a course instructor like any other Canvas object. If the blueprint course is synced and the instructor has modified unlocked objects in the associated course, unlocked objects are not overwritten with the synced changes.
Unlocked blueprint objects can be locked at any time. If you lock an unpublished object, and that object was previously removed from an associated course, the object will be replaced in the associated course.
Object Management
This article shows how to lock an object from the Assignments page. Objects can also be managed in the Files, Modules, Pages, and Quizzes.
In Modules, only individual module items can be locked. Changes to the modules structure are triggered as part of a course sync.
