The technology which is used computer hardware and software to create or modify any drafting or designing model for manufacturing to full fill the need of the customer is known as Computer-Aided Design (CAD). In the other way, we can also say that the cad model is a graphical representation / virtual prototype of a physical part or object to assist to design process and manufacturing. It can also refer to the use of computer hardware and software to prepare representational image files or gathering some basic information about the object to be manufactured. CAD also refers to the use of computer hardware and software to prepare to explode – assembling of various no of parts in an assembly, mechanism videos between fixed and moving parts etc.
CAD can be derived into two categories as follows:-
The number of soft wares is used in the present scenario for CAD as per requirement in the field Mechanical, Civil, Electrical, Interior Architecture etc. like AutoCAD (2D Specifically). In the mechanical engineering Creo, CATIA, SolidWorks, Inventor, NX, etc. In the electrical engineering AutoCAD electrical. In the Civil engineering \ Architecture civil 3D, Staad Pro, Revit, google sketch up, 3DS Max etc.
The CAD software is being used on a large scale basis by a number of engineering professionals and firms for various applications. The most common application of CAD software is designing and drafting. Here are some of the benefits of implementing CAD systems in companies:
Following are some of the key advantages of using CAD software.
As technology continues to strive forward architecture CAD introduced in late 1980s.Architecture and CAD have played a major role in virtual reality. Around 1995, Matsushita Electronic Industries produced a virtual house with its bases in CAD. Since then, a number of projects that incorporated virtual reality with CAD began to grow.
The most basic CAD packages permit construction and editing of drawings using geometric primitives, parts stored in the computer’s libraries & 3D geometric modelling and viewing, usually wireframe and solid modelling.
When it comes to the construction of civil projects, there is a lot of designing that is involved. Planning bridges and even towers and other structures needs special consideration of some of the main points. Even a minor flaw in the design can be problematic and it can create a big ruckus. This is why CAD software is put to use as the different tools will come in handy in sketching the fine details of what you really desire.
Computer-aided design is the use of computer systems to assist in the creation, modification, analysis or optimization of engineering design. The CAD software is used to increase the productivity of the designer, improve the quality of design, improve communication through documentation and create a database for manufacturing. CAD output is often in the form of electronic files for print, manufacturing or other manufacturing processes.
The technical and engineering drawings and images must convey information such as materials, processes, dimensions and tolerances according to application-specific conventions. The CAD may be used to design curves and figures in two-dimensional (2D) space or curves, surfaces and solids in three-dimensional (3D) space. CAD is also used to produce computer animation for the special effects used in, for example, advertising and technical manuals.
CAD is an important industrial art and is the way projects come true. It is extensively used in many applications, including automotive, shipbuilding and aerospace industries, and in industrial design. The CAD process and outputs are essential to successful solutions for engineering and manufacturing problems.
CAD software helps us explore ideas, visualize concepts through photo-realistic
renderings and movies and simulates how the design project will perform in the real world.
Electrical drawings are the representation of electrical components and connected wiring to fulfil a specific purpose. An electrical drawing can be of a house, industry or an electrical panel. Also, an electrical drawing can be divided into the following categories:
