Technical drawing is the means of conveying ideas or transforming ideas into reality. This study is an appraisal of Teacher/Student Acceptance and Satisfaction with the use of CAD package as compared to conventional method for teaching technical drawing at secondary school level in Lagos State. The study was carried out in Lagos State Senior Secondary Schools that offer technical drawing and has presented students in Technical Drawing in external examinations for five years. The design adopted for the study was survey andthe population for the study included all teachers teaching technical drawing and students of SS11 offering the subject. Four and two research questions and hypotheses respectively were raised to guide the study. A 30 structured questionnaire items was developed for the study. The instrument was rated in four-points rating scale of Very Effective (4), Effective (3), Not Effective (2) and Not Very Effective (1). The findings of the study showed that the CAD is very effective in teaching and learning technical drawing, CAD facilities are not adequate in schools and therefore teachers and students do not regularly use them both in their private studies and classroom activities. It was recommended that among others that teachers of technical drawing should undergo refreshers training on CAD application, schools should provide a well-equipped drawing studio, teachers of technical drawing should regularly use CAD in teaching technical drawingand students should be encouraged to practice technical drawing with CAD.
