Copying a Gate and Pasting It as a New Top Gate
To create a new fault tree, you can copy an existing gate in the tree and then paste it as a top gate.
1. In the FTA Table, select the record for the gate.
2. If you want to also copy child items, right-click the gate in the diagram and select Select Branch.
3. In the diagram, right-click the gate and select Copy.
4. In an empty area of the diagram, right-click and select Paste as Top Gate.
The gate is copied to a top gate, thereby creating a new tree. If you selected the branch along with the gate, the child items for this gate are also copied into the new diagram.
