Introduction To AutoCAD

The origin of AutoCAD completely revolutionized the design industry, leading to a new era of design practices that are computer-based. Earlier, designers would have to spend a lot of time designing and measuring every line. But AutoCAD replaced all that. Rather than relying on pen and paper, designers can concentrate more on the design itself. AutoCAD courses enable designers to pay more attention to ideation, automating the ongoing process instead.

What is an AutoCAD program? 

AutoCAD is a CAD-type software designed for drawing and modeling in 2D and 3D. It undergoes the creation and modification of geometric models with an endless capacity to design and develop all types of structures and objects. 

The potential to work in different fields has let AutoCAD transform its traditional use in the World of engineering and architecture, to explore the dimension of graphic and interior design.

Today, AutoCAD has a wide range of specialized auxiliary tools that make up every kind of industrial field linked to 2D and 3D modeling.

History Of AutoCAD

A group of programmers under the supervision of John Walker developed the pioneer version of AutoCAD in 1982. This software was created by another member of their team, Michael Riddle. AutoCAD allows the industry to grow steadily to the present day. In that course of time, Autodesk faced the departure of John Walker and welcomed Carol Bartz. He grew the company to accelerate its success and AutoCAD’s market evolution became indisputable. Right now Autodesk offers a wide range of software tools directed at modeling, design, applications, and rendering.

Features of AutoCAD

AutoCAD is rectifying its features for 2D and 3D design. Its collaboration with the cloud and its compatibility with other programs, broaden its functionalities.

In the updated version, AutoCAD has eventually upgraded the functions for 2D design, rectifying the accuracy of the tools by revamping some options

  • Linkable forms with spreadsheets applications
  • Create dimensions automatically
  • Ability to extract data from blocks, objects, and attributes
  • Dynamic blocks
  • Matrices creation

3D modeling has focussed on upgrading rendering and compatibility with other programs which accompany AutoCAD.

  • Attach point cloud files
  • More realistic 3D modeling
  • Application of realistic lighting in renderings
  • Rendering directly in the cloud
  • Create cross-sectional drawings

Latest Features

Autodesk is working with the latest technologies, to improve cross-device compatibility and work effortlessly in the cloud:

  • Multi-device support
  • Cloud storage and querying
  • Quick measurement section
  • Files progress history
  • Improved performance
  • Block pallet
  • Innovative AutoCAD features

Benefits Of AutoCAD

Here are the key benefits of excelling in AutoCAD that should never be overlooked:

  • Draw to scale: You can choose the right units of measurement by AutoCAD and are able to draw models at a 1:1 scale.
  • Easy Layout and Viewing: The interface is convenient to navigate with multiple tools allowing you to view your drawing from various perspectives.
  • Draw Accurately: AutoCAD with variable options allows you to set and align objects accurately.
  • Make Changes conveniently and minimize the risk of error: You can create designs accurately and in a narrow frame of time.
  • Identify Design Problems: visualizing your item via AutoCAD allows you to identify and solve issues with design in the initial stages.
  • Calculate Material Quantities for Production: By the use of a scanning tool in AutoCAD
  • Store and transfer data safely: Latest features of AutoCAD allow you to store and transfer data safely.
  • Save time and money: It is incredibly efficient 

How Does AutoCAD Work?

This software works in layers along with vector images.

User Interface

 The entire interface of AutoCAD is crafted for the designs of structures and plans and is categorized as follows:

  • Graphic Area: We craft our designs here
  • Option Ribbon: Locations of most common actions
  • Pull-down menu bar and toolboxes
  • Status bar: Holds all information about grid control buttons, coordinates, etc
  • Command line: For interaction with programs to get information and calculation


The commands bar is the best tool in AutoCAD to speed up your work. There is a wide range of commands available and a few of them are:

  • AREA for perimeter and area calculation
  • CHSPACE for scaling objects automatically
  • MULTIPLE to replicate the same action
  • OOPS to delete
  • EXTEND to lengthen an object

Blocks and Libraries

AutoCAD blocks are building elements and can be categorized into themed libraries with various types of specific object blocks.


Layers in AutoCAD are the key method for arranging objects in a drawing by purpose or function. Layers have the capability to reduce the visual complexity of a drawing and enhance display performance by hiding unnecessary information.


A View comprises a specific magnification, orientation, and location that you can easily save and name accordingly. A named view can save a snapshot of the current layer visibility settings.

Who Uses AutoCAD?


AutoCAD is widely used by architects, who use it to create detailed architectural designs and draft detailed blueprints from buildings, commercial projects, homes, and more. The program’s features are very unique and versatile and cover both floor plans and elevations, including different surface features like windows and roofs. This software would let you critically analyze the building's capacity and strength before even constructing its layout on a building site. So, it can avoid serious hazardous issues headway.


There is a special feature of AutoCAD for engineers named Civil 3D. This Civil 3D design software helps architects and Civil Engineers in designing, planning, and managing civil infrastructure projects like roads and highways, rails, airports, etc. This software is also helpful in Building Information Modeling (BMI) and streamlining the design process through hundreds of techniques created for water projects, land development, and transportation.

AutoCAD is equally beneficial for Mechanical Engineers. Mechanical engineering is a significant field in the computer, automotive, electronics, aerospace, and manufacturing industry. These engineers not only design but also develop, construct, and test different mechanical appliances, machines, engines, and tools. 

Interior Designers

Interior designers can utilize AutoCAD to create plans for functional indoor spaces. There are endless possibilities for interior designers to use this program in an efficient way.

Other Professions

Other professions that can use this software to simplify their workflow and achieve accurate results include:

  • Electrical engineers
  • Industrial engineers and designers
  • Structural engineers
  • Manufacturing engineers
  • Plumbing, HVAC, and MEP designers
  • Fashion designers
  • Artists, and sculptors
  • Project managers
