Summary:
Throughout the first term, students have been introduced to various aspects of Technical Drawing, including special curves (loci), surface development, intersections of solids, and pictorial drawings. The term included a blend of theoretical learning, practical demonstrations, and group activities aimed at reinforcing critical thinking, problem-solving, and collaboration skills. The mid-term and end-of-term assessments provided opportunities to evaluate and consolidate their knowledge, preparing them effectively for further studies in Technical Drawing.
