You can duplicate an entire structure using the following tool from the PDM workbench contextual menu. It will duplicate the entire structure, top down from the selected node.

Once clicked, a list of the selected structure will open in the duplicate window, see the image below. As standard the whole structure will be set to duplicate, indicated with a green tick in the first column.

If this is not desired, documents can individually be set to ‘do not copy’ by selecting the row, then unticking the ’copy node’ check box and pressing ‘apply’ on the right side of the window. These nodes will then be highlighted with a red cross. Alternatively, the entire structure can be deselected by unticking the ‘duplicate all’ box at the top.
Note, documents that are not duplicated will still be copied into the new assembly. 

Target names must be defined for all duplicated items; however, these are only temporary as the new documents will automatically be assigned an ST document number on first save in the PLM. The names can be defined for all nodes by filling the “Source rule” and “Target rule” with a wildcard “*” as shown above. Alternatively, they can be defined individually using the box on the right.

Once finalised press okay and the duplicated structure will be opened in a new window. This can be saved into the PLM through a separate step, where new ST documents numbers will be assigned.

Associated drawings of the structure can be duplicated with the assembly. This setting can be enabled via the PWB Options window, found on the toolbar. If the duplication of drawings is enabled in this options window, they will be displayed in the list of objects to duplicate.
