Alternate path for process flow

How do I make it so that the part from the feeder can go from the conveyor to either the Generic Lathe or the ProLathe before going back to the conveyor.

It would be like an alternate path, if the Generic Lathe is occupied, the component will go to the ProLathe instead.

Thanks for the reply, I am assuming you are referring to this method of stacking processes.

But I can’t seem to stack the processes up like that, probably because I am only using VC 4.3 professional. Is there another way?

Stacking processes is only available in newer versions.
In 4.3 you could rename your 2 machine processes so that they have the same name.
