While working on a checked-out model, you can revert to the last checked-in version of the model to cancel all changes that you have made since checking out the model.
The model whose changes you want to cancel is checked out by you.
...
1. Choose Model → Manage Models.
2. In the Manage Models dialog box, expand the Shared Repository or source control node and select the checked-out model whose changes you want to cancel.
3. Click the Revert button.
The version of the model that you are working on is discarded and reverts back to the previously checked in version. All content changes made after the model was checked out are cancelled. The model icon in the tree changes to indicate that the model is checked in.
If the model was open while you reverted it, the open version is no longer synchronized with the version that is checked in. For more information, see Synchronizing a Model.
