This document contains (1) the final report of a project to develop a computer-aided drafting (CAD) curriculum and (2) a competency-based unit of instruction for use with the CADAPPLE system. The final report states the problem and project objective, presents conclusions and recommendations, and includes survey instruments. The unit is designed for second-year vocational drafting students with a solid background in mechanical drafting. Computer experience is helpful but not required. Introductory materials include a list of required hardware, software, and materials; student competencies; student objectives; and lesson procedure. Five sections cover terminology, input, create, modify, and levels. The first page of each section provides this information: lists of readings and worksheets, statement of the problem, and steps of procedure. Each section also provides handouts and worksheets. Other contents include instructions for (1) doing a detail drawing as a final project for the unit, (2) getting CADAPPLE "up," (3) preparing CADAPPLE for "A" or "B" size drawing, (4) saving one's work, (5) loading a drawing, and (6) plotting the drawing.
