In this course, instructors introduce CAD techniques for aeronautical drafting, building on the skills learned in the beginning CAD course. Aeronautical CAD students create detailed engineering drawings using CAD software such as Autocad,Catia,Solidworks. Industry standards for engineering design, including geometric dimensions and tolerance standards, are incorporated in class work. Students study the function of individual machine components and then design each component using CAD software. Coursework concentrates on material choice, precision calculations and cost estimates. A portion of the course is focused on the interconnectivity of aeronautical elements such as belts, bearings, cams and shafts, in machine design.
