Typically, we just produce one drawing and indicate that the second part is of the opposite hand.
I guess it would really depend on what the vendor needs. Does the vendor use the solid model with a CAD/CAM package to generate machine code? Your best bet would be to discuss this with the vendor (machinist). It should all come down to the cost of doing business. If it costs you $100 to make a second drawing and saves $200 in production time, make two drawings. If the vendor will not pass the cost savings down to you, don't. DimensionalSolutions@Core.com
