UNIT-I (COMPUTER AIDED DESIGN)
In general, a Computer Aided Design (CAD) package has three components:
a) Design, b) Analysis, and c) Visualization, as shown in the sketch. A brief description
of these components follows.
a) Design: Design refers to geometric modeling, i.e., 2-D and 3-D modeling, including,
drafting, part creation, creation of drawings with various views of the part, assemblies
of the parts, etc.
b) Analysis: Analysis refers to finite element analysis, optimization, and other number
crunching engineering analyses. In general, a geometric model is first created and
then the model is analyzed for loads, stresses, moment of inertia, and volume, etc.
c) Visualization: Visualization refers to computer graphics, which includes: rendering
a model, creation of pie charts, contour plots, shading a model, sizing, animation, etc.
