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!
