Check Out
In order to modify a CAD document which exists in the Windchill Workspace, you must check out the document. Check Out reserves the CAD document in the Commonspace for that particular user, preventing other users from checking-in changes for the same CAD document. It creates a working copy of the document in your Workspace, which holds your changes until you check in the document.
You can access the Check Out command either in the Windchill Workgroup Manager client or in NX.
To access Check Out in NX, click Windchill > Check Out.
To access Check Out in the client, select the object and then, click File > Check Out. Alternatively, you can right-click the object, and on the Context menu, click Check Out, or click in the Toolbar or in the Action column.

Windchill supports the checking out of a non-latest iterations of a CAD document, and the subsequent checking in of that iteration as the latest iteration. This allows you to revert to an earlier version of a design. For more information on checking out non-latest iterations, see Checking Out Non-latest Objects.
