A New Drawing Office Appliance: The Glenn Martin ‘Axonograph’ for Producing Three Dimensional Prints

SOME type of three dimensional drawing has long been recognized as the ideal form of production illustration but they have seldom been used because of the difficulties involved in their preparation. The Glenn L. Martin Company of Baltimore, Maryland, U.S.A., have developed a technique, which includes a machine that cuts 50 to 80 per cent off the time required to prepare a trimctric drawing and four new drawing instruments, that offers promise of considerable simplification.
