Hello,
The maximum number of passes per operation is 3, rough, middle and finish.
However, you can copy n paste the operations to give 2 Goround commands, this will give a maximum of 6 passes. Paste again and this will allow up to 9 passes.
You will need to set each pass to be active and have the offset you require. Although we call the passes rough, middle and finish they can in fact be any sort of pass, there is no intrinsic data associated with each pass, it's just what you set on each tab.
Hope this helps
Andre
