Modern Drawing also known as
Computer-Aided Design (CAD) or Computer-Aided Design and Drafting (CADD) is the
use of computer systems to assists in the creation, modification, analysis, and
optimization of a design. CAD output is often in the form of electronic files
for print or machining operations. As in the manual drafting of technical and
engineering drawings, the output of CAD must convey information, such as
materials, processes, dimensions, and tolerances according to
application-specific conventions.
CAD programs provides precise
dimensioning and positioning of the elements being drawn. It is also used to
produce computer animation for special effects in movies, advertising and
technical manuals. Because of its enormous economic importance, CAD has been a
major driving force for research in computational geometry, computer graphics,
and discrete differential geometry. It is used to increase the productivity of
the designer or architect, improve the quality of design, improve communication
through documentation and to create database for manufacturing.
In the new millinneum, CAD System is
widely use to create designs not only on structures of building but of many
others. Engineers and architects are the main beneficiaries of the CAD System.
It helps them to work more faster in matters of designing and planning. It also
helps them make and group all the ideas of the mind into a beautiful work of
art.
Uses
of Computer-Aided Design (CAD)
CAD is a useful tool for engineers and
architects. For people working in the designing industry, Computer-Aided Design
(CAD) is a techique that makes the work easy and handy. There are many essential/significant uses of
CAD in the community. Below are some of the uses of CAD:
·
photorealistic rendering;
·
creation of photo simulation;
·
computer animation for special effects in movies,
advertising and technical manuals;
·
computer graphics
·
designing curves, figures, surfaces and solids in
two-dimensional (2D) space and three-dimensional (3D) space.
Advantages
and Disadvantages of CAD
Advantages
and disadvantages are common properties of any material, tool, object and etc.
With the many uses of CAD (Computer-Aided Design) in the society not only in
the designing industry, advantages and disadvantages are always present in any
form. Below, on Table 1, are some of the advantages and disadvantages in using
the CAD System:
Table
1. Advantages and Disadvantages in using CAD
ADVANTAGES
|
DISADVANTAGES
|
·
No need for scaling. All drawing is done
full-size;
|
·
If computer problem will occur, all data will be
lost;
|
·
The screen drawing can be set to any size with a
click of a button;
|
·
If not checked properly, the object created can
go very wrong;
|
·
All tools needed are supplied by the program;
|
·
Can be very expensive;
|
·
Absolute accuracy can be maintained;
|
·
Can be hard to do and handling needs training;
|
·
Production details can be extracted directly
from the drawing;
|
·
Since not manual, its very hard to insure
exactly what is wanted by the designer;
|
·
Eliminates the need for full-size set outs;
|
·
Sometimes,
you can't do everything you want to because the tools aren't
available.
|
·
Your work is copied and stored off the computer
for security, you may never lose your work again!;
|
|
·
Drawings are stored on stick rather than in a
bulky folder;
|
|
·
Dimensioning is almost automatic.

(Table
1. On the above table, there are more advantages than the disadvantages in
using the CAD System. In this condition, we could conclude that using CAD could
be a helpful tool for studying, designing and planning.)
Benefits
in using CAD (Computer-Aided Design)
CAD is
useful to people. It also brings advantages and disadvantages to people and
with the environment. Who would be the possible beneficiary of CAD System? What
would be its benefits to people? environment? community? These are questions
that emphasize the importance of CAD and its benefits. Below are the benefits
in using the CAD System:
◦
Save time and money and reduce errors with the
dynamic engineering model.
◦
Reduce purchase, deployment, and support costs
with one complete solution.
◦
Increase value to client by delivering more design
alternatives in less time.
◦
Take full advantage of existing AutoCAD skills to
get up to speed quickly.
◦
Create production sheets faster.
◦
Be sure that production drafting is always in sync
with your design.
◦
Complete projects faster and reduce the chance of
coordination errors using the Civil 3D project environment.
◦
Exploit data compatibility.
◦
Build a foundation for your custom solution.
◦
Clearly communicate design intent and complete
final proposals with realistic 3D rendering.
Conclusion
With the
uses of the CAD, we could conclude that it supports the needs of designers in
designing. Photorealistic rendering, creation of photo simulation, computer
animation for special effects in movies, advertising and technical manuals,
computer graphics, designing curves, figures, surfaces and solids in
two-dimensional (2D) space and three-dimensional (3D) space, these are some of
the uses of the CAD System that supports the basic needs in designing. It can
be an exchange tool in designing and planning because it uses computer programs
to create a design or plan, so, it mainly shows that manual drawing using the
instruments is on the outside diameter. However, its advantages and
disadvantages also inhibits the possible benefits and consequences in using the
modern drawing (CAD). Furthermore, in the above data showed, we can identify
that the CAD System is a useful tool because it gives more advantages than its
disadvantages.
CAD System has its best ways of making
the foundation of designing industry tough and durable. It supports the need of
designers, engineers, and architects to develop their designing skills more
enough. CAD (Computer-Aided Design) has comletely change the drafting business
and made the storage and the retrieval of projects much easier. Hovever, manual
drawing is still important and provides the basics in learning drawing. The
goal of automated CAD Systems is to increase efficiency; they are not
necessarily the best way to allow newcomers to understand the geometrical
principles of Solid Modeling, but still, it is a good technique in designing
and planning structures or figures.
