The abbreviation CAD stands for Computer-Aided Design and uses programs to create, visualize, modify, and optimize valuable drawing tools. It is also known as Computer-Aided Design and Drafting. CAD has saved time, money, and increased the productivity of the design process. As you know what the CAD abbreviation means, you must now learn that it is used to make technical drawings with 3D objects that represent real-world objects like cars, airplanes, buildings, machines, etc. The industries use it regularly in films, entertainment, planning, and civil works.
A Brief History of CAD
The early development and designing of Computer-Aided Design (check the CAD meaning) began as early as the 1940s. It was used to optimize and analyze power systems. Later, Ivan Sutherland in the 60’s developed a sketchpad that literally set the balls rolling for CAD. The use of CAD was limited to large companies for a long time. Soon it gained prominence in homes and offices when computers became cheaper.
How Does CAD Work?
CAD was designed to remove the painful process of hand drawing. You would need a sound knowledge of computers, technical drawing, and a robust idea in your mind. It will be good if you can make some drawings beforehand on a sheet of paper. Sketches save you a lot of time and help to streamline your process. There is a small rectangular box at the bottom screen with commands to type instructions. It is known as the command window. The program has a host of algorithms that create different lines, shapes, and curves.
Different Types of Input Devices
A designer inputs instructions into the software for a proper CAD result (check the CAD meaning).
Several input devices used are:
Bluetooth CAD mouse,
Graphics Tablet,
Vertical Tablet
Types of CAD Software
There are two kinds of CAD software in 2D and 3D versions.
2D CAD
2D CAD systems were developed in the ’70s and consisted of drawings on one flat plane representing the length and width. These were built using a combination of straight or curvy lines including basic geometric shapes. AutoCAD and CADkey are the most commonly used programs.
3D CAD
This incorporates the 3rd dimension of depth or height in the technical drawings enabling designers to integrate real-life images. It helps to visualize real-life concepts and aids marketing teams immensely. The most popular programs are known as Solid Modeling Software because they manage to model every part of the product.
Benefits of CAD
The few advantages of CAD are:
Sharing a file easily
Different layered drawings
Accuracy of the drawings
Solid record-keeping process
The integrity of the structure
CAD – Its Applications
CAD is an advanced software for creating designs and generating technical drawings in 2D and 3D by architects, engineers, drafters, & artists.
CAD utilizes computers as a tool for all functions that are involved in the design process. the main functions that would utilize the computer are layout designs for the overall assembly, individual component modeling, assembly modeling, interference and tolerance stock checking, engineering drawings, etc.
Advantages of CAD
CAD is faster and more accurate than other conventional methods.
It helps to construct various models as it is very easy to operate.
Under CAD it is possible to manipulate various dimensions, attributes, and distances of the drawing elements.
The modification of a model is very easy and would make the designers’ tasks very simple for any future requirement.
Professional CAD packages provide 3D visualization capability so that the designers can see the products being designed from several different orientations.
Most CAD systems currently available offer extensive capabilities for developing engineering drawings. these capabilities are :
automatic cross-hatching of surfaces in drawing from wireframe models
capability to write text on the drawings.
semi-automatic dimensioning
The dimensions can be obtained from the database. Dimensioning features include linear or angular conventions depending on which is more appropriate. Dimensions are displayed in decimal or fractional motion.
Course content of Computer-aided Design
Course objectives of Computer-aided Design are:
Development of software computer interface in design of various elements.
Use of software for manufacturing and automation of manufacturing methods.
The course contents are:
Module 1: Fundamentals of CAD
Module 2: Computer graphics software and Database.
Module 3: CAM introduction, numerical control NC part programming
Module 4: Problems with conventional NC Technology.
Conclusion
The detailed and full meaning of CAD software has revolutionized the world of technical drawings. These programs are used across a wide range of industries like the aeronautical, fashion, and film industries. This guide will definitely help you to get a comprehensive understanding of this awesome technology.
