To Create a Checkpoint Branch
You can create a branch from a checkpoint with one or more successor checkpoints. To create a second branch from a checkpoint, activate this checkpoint again and repeat the procedure.
1. Select an existing checkpoint and click or right-click and select Activate.
2. Continue the design process and add a new checkpoint. A new branch is created. The new checkpoint is the active checkpoint.
