When you check out a project, you can check out all the project document versions contained within a project configuration in a single check out.
You must create the configuration from the project contextual menu (see Creating a configuration).
Open the Check Out Project window.
Select the appropriate parameters (see Check out parameters) including the configuration to check out, and then click OK to check out the document versions of the configuration, and add them to your workspace. If you have selected the Merge document option, the Check Out Model window will open to allow you to review all the differences between the local and repository versions and to apply or reject them as appropriate.
