b) Percentage of I class 80
2. Course description :
Computer Aided Design aims at introducing the students about computer
applications in design process. The students should be familiar in the design area.
Design of the parts means designing a new part or modifying the existing part. The
subject explains about the design of different components by considering various
loads acting on it. The complete design of the component also includes the analysis of
the designed component. The analysis includes kinematic analysis, mass properties
analysis like moment of Inertia, Centroid etc. The subject makes the students to learn
different analysis packages like ANSYS, NASTRON and NISA –II. The subject gives
idea about artificial intelligence and its applications in computer aided design.
3. Scope and objectives :
