Integrated Computer-Aided Drafting Instruction (ICADI).
Chen, C. Y.; McCampbell, David H.
Until recently, computer-aided drafting and design (CAD) systems were almost exclusively operated on mainframes or minicomputers and their cost prohibited many schools from offering CAD instruction. Today, many powerful personal computers are capable of performing the high-speed calculation and analysis required by the CAD application; however, the price of such a system is still quite high. The faculty members in the Industrial Technology Department at West Texas State University have developed and integrated a CAD system into the freshman engineering graphics courses. After reviewing course objectives and essential CAD fundamentals and assessing the existing computer equipment in the department, they developed a package of integrated computer-aided drafting instruction (ICADI) materials, including computer software and instructional materials for classroom use. Special drafting procedures allow users to create drawings in a very short time without previous programming or computer operation experience. Unlike expensive and sophisticated systems, ICADI does not store data for a drawing in the computer's internal memory and thus does not require a large memory. The video screen of the systems does not display high-resolution drawing, instead it displays drafting procedures and parameters associated with the drawings. The output device for the ICADI system is a plotter that provides excellent resolution and line quality. Although the ICADI computer software has limitations, the system does enable the student to learn CAD concepts rapidly, gain experience in CAD usage, and produce high-quality drawings simply and directly.
