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.

• 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.

• 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-

Geometric Modeling

• 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 systems basic building
  blocks.
• It is a subfield of applied mathematics and
  computational geometry that studies methods and
  algorithms for mathematically describing shapes.

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

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

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.
