'Engineering Graphics - CAD' is a course offered in the first semester of  B. Tech. programs at the School of Engineering, Amrita Vishwa Vidyapeetham.

Course Objectives

  • To develop drawings using Bureau of Indian Standards (BIS)
  • To communicate effectively through drawings
  • To enhance visualization skills, which will facilitate the understanding of engineering systems.
