You just have to eyeball it. It doesn't have to be exact. If the the outside diameter, inside diameter, and curves of the races are reasonably close, you're in business.
I once tried one of those cheap sets in a Specialized wheel I pulled from the dumpster. It rolled nicely in the truing stand, but after a few miles it would flutter under braking. Since I had no idea what the original cones looked like, back into the dumpster it went.
