“Computers themselves, and software yet to be developed, will revolutionize the way we learn.” -Steve Jobs
Steve Jobs couldn’t have been more right; the software systems that have been developed in the last few decades have changed the way simple tasks are completed and ultimately changed the world.
For example, the invention of the web browser has revolutionised the way we access information. Search engines such as Google and Yahoo! organised all the information that could be accessed and the rest is history!
As a millennial born in the late 90s, I can’t even remember a world when the internet and modern-day software systems didn’t have a major influence on society.
Nevertheless, it is essential to state that software such as the web browser is just ONE of many modern-day advances in technology that has shaped the world.
Software systems such as Quickbooks, Office 365, NetSuite, and Microsoft Dynamics are frequently used by some of the most-renowned businesses around the world.
In today’s article, we will briefly discuss an introduction to CAD tools on AutoCAD, along with basics and the original drawing and modifying tools of the AutoCAD program.
An Introduction to the AutoCAD Basics
Our friends at Autodesk have created a fantastic Hitchhiker’s Guide to help beginners get through the AutoCAD basics. (Source: Autodesk)
Many AutoCAD experts have provided indispensable advice, tips, and tricks on blogs, websites, videos, and books about how to effectively use AutoCAD.
Manyfirst-time AutoCAD users have heard that mastering the software takes much time and practise. While this statementis accurate, it is necessary to dive into the world of AutoCADto improve many technical skills and try new things.
Before starting a serious work project, it’s recommended to spend a day experimenting with the software to get used to all of its functions. Remember that practice makes perfect and the learning experience is ongoing.
What information is covered in this Hitchhiker’s Guide?
Well, for starters Autodesk suggests that beginners follow the steps to understand AutoCAD’s tools:
Notes & Labels,
The free-trial of AutoCAD that is offered on the Autodesk site is a brilliant way to get familiar with the tools and aspects of AutoCAD before following the steps mentioned above!
Try to get advice from more experienced colleagues and ask them what helped when they first started using AutoCAD. Hiring a professional Superprof tutor that has experience with AutoCAD is also a brilliant option.
In the following sections, we will consider the essential drawing and modifying tools.
Basic Drawing Tools

How do I draw and create the blueprint or product I wish to fabricate on the AutoCAD system?
Therefore, to guarantee a successful 3D model or project on AutoCAD from the beginning, the following are some of the most basic drawing tools that users will need to manage along with their simple definition:
Point: one of the most basic parts of a CAD drawing building design, a point is used to create a symbol on the drawing that is tied to another specific location. In the software, points are defined by the coordinates (x,y,z).
Polygon: multisided shapes such as pentagons or hexagons, polygons can be frequently used on the AutoCAD system for drawing. The software requests the number of sides and the desired shape. “Closed Polygons” can be edited using the command PEDIT.
Arc: a circle segment that can be defined by selecting three points through in which AutoCAD can generate an arc.
Circle: the only variables to create a circle are the radius and the centre point. The shortcut to creating a loop on AutoCAD is “c.”
Spline: a spline can be defined as a curve that is generated by specific mathematical equations. The user can select as many verticles as they wish and AutoCAD will release a spline curve that incorporates all of these points. Splines are most often used for cosmetic purposes, and the program shortcut is “spl.”
Ellipse: commonly recognised as an oval, an ellipse is very similar to a circle except it requires a radius to be defined for both their horizontal and vertical exponents.
Hatch: known on AutoCAD software as space fillers, they can be made of a solid colour or a more specific pattern that was designed by the user. They can be applied to a particular object such as looped polyline.
Text: by using this option, a text string is inserted into the drawing. It is essential to state that the AutoCAD system uses two forms of text entry: single line and multiline. The distinct types are known as DTEXT and MTEXT. Also, TEXT can be used in areas that are unspecified and undefined.
Basic Modifying Tools

The following are some of the most basic modifying tools:
Erase: when you make a mistake, erasing saves the day! A simple tool that can be used by selecting the object you wish to eliminate and then pressing the erase tool.
Copy: everyone who uses a computer can identify with the copy and paste functions and it is the same with the AutoCAD software. To move a selected object from one place to another the copy tool is used. To copy the user selects two points and the object is copied using two positions as base points. Points can be selected by using the keyboard and typing in the coordinates or by clicking anywhere on the screen. The shortcut is “cp/co.”
Mirror: the user defines two points, and the reflected object is generated across the chosen line with all components reversed. While using this tool, any selected object can create a mirror image. The keyboard shortcut to use this tool is “mi.”
Offset: the option of offset is considered to be almost the same as the copy option; it is used in specific situations since the result will likely be smaller or more prominent than the original. The shortcut for using the offset tool on the AutoCAD system is “o.”
Array: completing a variety is a quick way of doing a lot of copying. It is essential to state that there are two types of arrays: polar and grid. To make a polar grid the AutoCAD system asks the user how many copies they wish to include in their draft, and on the other hand, to fabricate a grid array the user selects how many columns and rows are needed to complete the task at hand. The AutoCAD shortcut to make an array is “ar.”
Scale: to use this function the user selects object or objects, and the scaling factor on the CAD program is defined. Using the scale option on AutoCAD is a great way to change a drawing from metres to millimetres without having to make things so complicated for users.
