Understanding AutoCAD 

This software has a rich history dating to its initial release in 1982. Developed by John Walker, AutoCAD revolutionised how drawings were created and managed. Over the years, it has evolved and introduced numerous innovative features, enhancing productivity and efficiency for its users. Today, it remains a top choice for professionals across various disciplines. But What is AutoCAD exactly? Let’s find out AutoCAD’s definition. 

AutoCAD, developed by Autodesk, is a powerful Computer-Aided Design software that has become an indispensable tool for professionals in various industries. Architects, Engineers, Designers, and Drafters can enjoy the benefits of this software. It provides a comprehensive platform for creating precise and detailed drawings, models, and designs. 

At its core, it is a digital drafting board that allows users to create 2D and 3D representations of objects and spaces. It offers many tools and functionalities that empower users to bring their creative visions to life accurately and efficiently.


 

How AutoCAD works?

 AutoCAD is a powerful design software used primarily for creating architectural plans, engineering drawings, and other technical designs. Here’s a breakdown of its interface:

a) Graphic area: This is where you create your designs. It’s like your canvas, where you draw lines, shapes, and objects.

b) Options ribbon: The ribbon contains tools and commands for common actions. You’ll find tools related to drawing, modifying, and managing your design elements.

c) Pull-down menu bar and toolboxes: The menu bar provides access to various AutoCAD commands and settings. Toolboxes offer specialised tools for tasks like dimensioning, text editing, and layer management.

d) Status bar: Located at the bottom of the screen, the status bar displays information such as coordinates, grid settings, and orthometric mode. It helps you keep track of essential details while working.

e) Command line: The command line allows you to interact with AutoCAD using text commands. You can enter specific instructions to perform tasks, get measurements, or gather information.

Now let’s take a look at features of AutoCAD: 

1) File type: DWG is the native file format used by AutoCAD, and it holds all of the information regarding the designs, geometries, and pictures of the original file. The software's broad adoption led to the creation of additional tools that allow native AutoCAD files to be widened and visualised via the Drawing eXchange File (DXF)  information exchange system.

2) Compatibilities with other programs: Using its vectorial system, AutoCAD not only exports to the standard DWG format but can also be used to export to other graphic design-oriented programmes like Adobe Illustrator or Corel Draw. You can also operate in combination with other CAD-style programmes.

3) Blocks and libraries: The native file format used by AutoCAD is called DWG, and it holds all of the details regarding the designs, geometries, and pictures of the original file. Due to the software's popularity, additional tools for viewing and even opening native AutoCAD files have been created via the DXF information exchange system.

4) Commands: The commands bar in AutoCAD can be positioned anywhere on the screen, from docked to floating, and it's one way to speed up your work. Commands are orders that enable you to carry out tasks quickly, such as saving your work, arc creation, object rounding, and item inserting. There is a vast array of commands that are readily accessible on the internet.

Some of the most useful are:

a) AREA: To figure out the chosen object's area and perimeter.

b) CHSPACE: This command allows you to automatically scale objects that are entered into the model from the workspace. 

c) MULTIPLE: Continue doing the same thing until you choose to cancel the command.

d) OOPS: Restores the last elements you have removed.

e) EXTEND: It serves to lengthen an object until it meets the edges of another one.
