Hi Peter

Thank you for your reply and assistance :)

The process you suggest using TCL appears to be the same as the 
workbench approach, in that it requires extracting and translating 
coordinates then rebuilding of features, rather than offering the 
capability to translate via the features wholly.

Since you have mentioned the TCL approach is a little more 
complicated, I think I will stick with workbench :)

Thanks again for your help!

Carly
