Type VI scale shall be open divided, with four plotting and two drafting edges. All scales shall be numbered direct, with every 1,000th unit of plotting scales and every sin
19、gle unitof the drafting scales numbered. Plotting scales shall have 1,000 units and drafting scales one unitto the left of the zero mark. Plotting scales shall have every 500th unit graduated. The first edgeshall be graduated in yards at 1:25,000, with 7,000 yards to the right of the zero. The two 5
