What are the basics of computer aided design?
What Is CAD?
The term “Computer-aided design,” more commonly referred to as CAD, describes the use of computers to facilitate the design process across a variety of industries. Building a whole model in an imagined digital environment is achievable using CAD software, allowing you to see characteristics like height, width, distance, material, or color before the model is used or manufactured for a specific application.To get more news about computer drafting and design, you can visit shine news official website.
In 1963, computer scientist Ivan Sutherland developed the first computer graphics application called "SketchPad". It allowed users to write or draw basic shapes directly on a screen with the aid of a special pencil.
Initially, CAD was used mainly for research purposes, but in the 1970s major aerospace and automotive companies began to develop their own software, and by the 1980s it was increasingly used in other industries. It wasn’t until the 1990s that programs like AutoCAD and CATIA were developed, enabling CAD usage across numerous professional fields.
Who Uses CAD?
Computer-aided design is used in the workflow of a wide range of professions. Projects in the arts, engineering and architecture use CAD software extensively. The following are just a few of the many industries that use CAD.
Mechanical Engineering
In mechanical engineering, CAD software such as AutoCAD or SolidWorks helps to design models so that they can be better understood without the need to create a physical prototype. In addition, the models can then be easily materialised as physical prototypes using machines such as a CNC or 3D printer.
Architecture / Construction
Today''s architects design 2D models in CAD programs such as AutoCAD so that clients can quickly understand sizes and layouts when designing a building or home.
Instead of the traditional method of drawing mock-ups by hand, CAD software can dramatically increase your productivity and allow you to easily make changes to the file without having to start from scratch.
Fashion industry
Designers in the fashion industry often use CAD software to create a three-dimensional model of a ring, for example.
In addition, programs such as AutoCAD can be used to quickly create 2D layouts for individual parts that will come together to create a finished product. An example would be designing all the components needed to make a leather handbag, which can be easily laid out using CAD.
Electrical engineering
CAD software is used extensively by electrical engineers to design electrical circuits and printed circuit boards (PCBs). It can also help electrical engineers design electrical systems for buildings and machinery.
2D CAD drafting
Most of us are familiar with two-dimensional computer-aided design, or 2D CAD. These are two-dimensional, flat drawings that show the shapes, layouts and details needed to reproduce or construct the item being designed. A wide range of industries use 2D CAD drawings, including fashion, interior design, civil engineering, architecture, automotive, cartography and aerospace.
3D CAD Modelling
Three-dimensional computer-aided design is known as 3D CAD. It can often be used in ways similar to 2D CAD drafting. How are they different?
3D CAD allows a greater level of detail to be incorporated into the models, which can better simulate real-world applications and the assembly and interaction of multiple components.
To put it another way, both 2D and 3D CAD can show the size and shape of an object, such as the contours and dimensions of a new car model or the floor plans of a building. But with 3D CAD, you can also test the model’s functionality and better communicate all the necessary information for production.
