THIRTY-SIX INSTRUCTORS, SUPERVISORS, AND DEPARTMENT CHAIRMEN IN AREAS OF DRAFTING, ENGINEERING, MANUFACTURING, AND COMPUTER TECHNOLOGY AT JUNIOR COLLEGES, TECHNICAL, AND AREA VOCATIONAL SCHOOLS IN 20 STATES ATTENDED A 3-WEEK SUMMER INSTITUTE TRAINING PROGRAM ON COMPUTER-AIDED DRAFTING AND DESIGN. EXPERIENCE IN PROGRAMING THE IBM SYSTEM 1620 WITH AN ON-LINE 1627 PLOTTER UTILIZING THE DRAFTING LANGUAGE WAS PROVIDED. THREE LANGUAGES WERE USED--THE DRAFTING LANGUAGE, COGO (COORDINATE GEOMETRY) USED IN CIVIL ENGINEERING, AND THE LANGUAGE FOR NUMERICAL CONTROL. THIS PUBLICATION CONTAINS (1) THE REFERENCE MATERIALS AND PROGRAMING EXERCISES USED IN THE INSTITUTE, INCLUDING ILLUSTRATIONS DRAWN AND DESIGNED WITH THE ON-LINE 1627 PLOTTER, (2) CODE INSTRUCTIONS FOR PROGRAMING THE PRATT-WHITNEY TAPE-O-MATIC DRILLING MACHINE, (3) DETAILED INSTRUCTIONS FOR USE OF THE AUTOSPOT (AUTOMATIC SYSTEM FOR POSITIONING TOOLS) PROGRAM SYSTEM, AND (4) PLOTTING ROUTINES FOR THE COGO SYSTEM WHICH ALLOW THE USER TO DISPLAY GRAPHICALLY ON AN IBM 1627 CALCOMP PLOTTER THE RESULTS OF THE COORDINATE COMPUTATION, WITH OR WITHOUT ANNOTATION, AND WITH OR WITHOUT CONNECTING STRAIGHT OR CIRCULAR LINES.
