Diploma in Mechanical EngineeringCourse Code: 3300007 GUJARAT TECHNOLOGICAL UNIVERSITY, AHMEDABAD, GUJARAT COURSE CURRICULUM 1. Programme Title: Diploma in Mechanical Engineering Semester: I Course Code: 3300007 Course Title: Basic Engineering Drawing RATIONALE: Engineering drawing is an effective language of engineers. It is the foundation block which strengthens the engineering & technological structure. Moreover, it is the transmitting link between ideas and realization. It is an attempt to develop fundamental understanding and application of engineering drawing. It covers knowledge & application of drawing instruments & also familiarizes the learner about Bureau of Indian standards. The curriculum aims at developing the ability to draw and read various drawings, curves & projections. The subject mainly focuses on use of drawing instruments, developing imagination and translating ideas. Developing the sense of drawing sequence and use of drawing instruments effectively yields not only with productive preparation of computer aided graphics but also yields with effective industrial applications ranging from marking to performance of operations. 2. LIST OF COMPETENCIES: The course content should be taught and implemented with the aim to develop different types of skills leading to the achievement of the following competencies. a: Prepare engineering drawings manually using standards. b: Use drawing equipments, instruments and materials. c: Develop the ability to imagine the shape of simple object from orthographic views and viseversa. 3.
