Commands available on elements in read-only mode
Overview
Elements in read-only mode cannot be directly modified. The available commands are used to make elements modifiable or to import them into the repository as they are.

Check-out
This command allows you to mark one or more units as reserved. Thus, if another user tries to make a reservation at a later date, the command will not work. When a check-out is run, the model is first updated, in order to carry out the modifications only on the latest version of the unit.
In hierarchical mode, the components of the element are also checked-out and imported.
Import from repository
This command updates the element with the contents present in the repository. It is used to retrieve all the modifications made to an element, without actually checking out the element in question.
