The document outlines the four phases of Computer-Aided Design (CAD) which include geometric modeling, engineering analysis, automatic drafting, and design evaluation. It emphasizes the historical development of CAD by pioneers such as Patrick Hanratty and Ivan Sutherland, and its application in various industries, including jewelry design. Additionally, it provides contact information for jewelry rendering services in India that offer CAD-related services.

2. What are the 4 Different Phases in Design While
Using CAD?
CAD or Computer-aided
design was introduced by
Patrick Hanratty and Ivan
Sutherland in the early 60s.
They designed this system
while working for General
Electric. A DAC program was
developed by Hanratty, the
first system to use
interactive graphics and a
numerical control
programming system.

3. • In 1963, Ivan Sutherland also designed a system
CRT which then broke new grounds in 3D computer
modeling and visual stimulation which was called
the basics of CAD.
• In 1971, a program called ADAM was developed
by Hanratty which was described as the first
commercially available integrated, interactive
graphics designs, drafting, and manufacturing
systems. You must be surprised to read this but
9/10 roots of CAD programs were found in ADAM.

4. • Currently, CAD is
used by manufacturers
or engineers and is also
used in the jewelry
industry. Yes, you read
that right! The jewelry
pieces we like to wear
are CAD-Designed
Jewelry.
• But today what we
are summarizing here
are the phases of CAD.
Below we have listed 4
different phases of
CAD- 4

5. • This phase of a CAD system
involves a system to develop a
mathematical description of the
geometry of an object.
• This operation summons the
creation of new geometric
models from the system’s basic
building blocks.
• It is a subfield of applied
mathematics and computational
geometry that studies methods
and algorithms for
mathematically describing
shapes.
Geometric Modeling

6. • This phase is used in industries like architecture,
civil and mechanical engineering, geology, and
medical image processing.
• Not only this geometric modeling is also used in
jewelry CAD design, for creating all those
geometric designs which a CAD jewelry designer.

7. Engineering Analysis
• This method is the
application of scientific
analytic principles and
processes to reveal the
properties and state of a
system, device, or
mechanism under study is
referred to as engineering
analysis.
• This phase proceeds by
separating the engineering
design into the mechanism
of operation or failure.

8. • It is the primary method for analyzing and
handling issues with remote systems such as
satellites and rovers.
• This phase is used in the engineering industry to
produce designs and models for mechanical
components.

9. Automatic Drafting
1. It is the process of
creating designs of any
particular parts and then
its assembly and detail
parts have to be made.
2. This includes
specifications of various
materials which is also
called a bill of material
used for the
manufacturing of the
components of the part.
3. Many designers including
the jewelry CAD designs
use the CAD software
exclusively for drafting

10. Design Review and Evaluation
• This phase is like a milestone in the whole
process of product development.
• In this phase, a design is evaluated against its
requirements and see if any changes are to be
made and is it better than any previous design.
• This phase is used in every field where CAD is
used to create designs whether it is civil or
mechanical industry or by CAD jewelry designs.

11. Many CAD Rendering Services
in India provide 2D drafting,
3D modeling, animation, and
much more for different
industries like civil and
mechanical engineering,
medical firms, and even the
jewelry industry.
