What is CAD? Computer-aided Design is software used by engineers, drafters, architects and artists to create a technical illustration or precision drawing. In other words, it is used to create 2D drawings or 3D models. Engineering drawings require the use of graphical symbols such as points, lines, curves, shapes and planes and CAD gives a detailed description of any component in a graphical form.

Types of CAD Drawings
Here is a list of common designs and drawings that can be made using CAD software:
- Floor Plans: These are scaled diagrams that help to visualize the footprint of the home, building or other structures.
- Technical Drawings and Blueprints: It is a detailed, scaled plan used to deliver exact specifications of how a structure should be made. Technical drawings are mechanical, architectural and engineering designs, while blueprints are the reproduction of technical drawings.
- Piping and Instrumentation Diagrams: These show the link between piping, instrumentation and other components in a physical process flow.
- HVAC Diagrams: Such drawings provide the details about the heating, ventilation and air conditioning system with a particular location.
- Site and Plot Plans: These are scaled drawings showcasing the proposed usage and development of the piece of land, that include the footprint of buildings, walkways, drainage, landscaping designs, etc.
- Electrical Schematics: These drawings give an insight into the different components of an electrical system and the relationship between them.
- Wiring Diagrams: These show the initial connection of wires to each other and to all other components in an electric system.

How to Choose the Best CAD Software?
When we search online, we come across enumerable options when it comes to picking CAD software for ourselves where each one of them has its own benefits and disadvantages. However, the best CAD software depends on what sort of CAD drawing you will be making as well as how much cost and time are you ready to invest in learning a new application. Let us take a look at some of the key factors to be considered before making a purchase:
1. Choosing Your Design
Whether you should be needing a 3D drawing or will 2D work for you? Knowing what type of CAD design you will be making helps you in choosing the right type of CAD software.
2. Consider Your Budget
The CAD software is available in the market range from free versions to those costing thousands of dollars. It is quite obvious the higher the cost, the software will be more advanced with robust features. Let suppose, you will be working on a 2D floor plan – paying thousands of dollars for added 3D features is of no use. Thus you need to ensure that you are paying exactly for the features that you require.
3. Time for Learning
When choosing the ideal CAD software for yourself, you need to consider the time that you will take to learn the product. The less time you take to learn, the more designs you can create.
4. Device Compatibility
The first thing you think of when purchasing software is that, whether this will work on my device or the program will just crash. Consider taking a program that offers additional benefits like an online tutorials, guides, phone support, customer services and other essential support resources.
5. Easy Sharing
Are you going to share your files with other CAD users? If so, ensures that the software you purchase can open files from those CAD programs as well as save or export files in a format that those programs can open.
CAD software allows architects and engineers to create, inspect and monitor engineering projects with an integrated GUI (Graphical User Interface) on a personal computer system. Based on market statistics, Autodesk – a leader in 3D design, engineering software released the AutoCAD in 1982. Before the development of AutoCAD, most commercial CAD programs ran on minicomputers with each CAD user working at a distinct graphics terminal. AutoCAD was introduced as a commercial computer-aided design and drafting software application running on microcomputers with internal graphics controllers. Supported by 750 training centres worldwide in 1994, it was used by architects, engineers, graphic designers, project managers and city planners.
Benefits of CAD Software
CAD was first introduced in 1957 by Dr Patrick J Hanratty – when he developed the first commercial numerical-control programming system ‘PRONTO’. During that time, it was not exactly an economic proposition due to the simple fact that “machines at those times were costly”. But with the emergence of minicomputers and microprocessors in the latter part of the twentieth century, engineers began using CAD files.
Prior to computer-aided designs, plans were made manually using pencil and paper, with every object or curve drawn by hand using protractors, rulers and drafting tools. Engineers and designers manually did calculations like a structural load on a component. All of this was time-consuming and prone to error. However, CAD has changed the landscape of the design process where designs can be created and edited in lesser time and saved for future applications. Also, CAD drawings are not restricted to the 2D space but can be viewed as a 3D object. Besides these, calculations are done using computer software, making it easier for professionals to test the viability of designs.
The latest 2020 AutoCAD software includes improved workflows across desktop, mobile and web with new features added such as blocks palette, cloud storage connectivity, New dark theme, Enhanced DWG compare, and much more. In addition, it has industry-specific toolsets such as AutoCAD Architecture, Electrical, Map 3D, Mechanical, MEP, Plant 3D and Raster Design.
