# Learn AutoCAD basics: DAY 1

Welcome to Learn AutoCAD 2D basics in 21 DAYS!

Here is the first DAY. We will on this journey make use of all basic commands in AutoCAD.

The  Attempt: Handing you enough skills that you give you confidence to continue learning auto-didactically.

## Learning AutoCAD Basics

Today we will start from what you need to know on Day 1. You need to have visited these AutoCAD tutorial before diving into the following. (Jump this step and read further down, if you feel that you can handle the rest of the content without needing anything else, feel free to do so).

## Coordinate system

In AutoCAD, the Drawing Area is composed by a sheet in which every location has the particularity of having its own coordinate represented by x, y and z.

Since we are going to be solely working in 2D in this series, we can forget about the z component of the coordinate system.

Looking at the following image, you will notice that each corner of the figure has coordinates

Though it is true you wont be using this a lot while drawing in AutoCAD, we will spend a minute talking about it. At this point, I will suggest you disable the Dynamic input before trying the following.

We will try creating the previous image using the coordinate system and the command window. It is simple, the concept will be to use the four points to draw the quadrilateral.

To do that using autoCAD:

1. Type LINE and Press Enter
2. Type 9,9 and Press Enter
3. Type 25,9 and Press Enter
4. Type 20,17 Press Enter
5. Type 14,17 Press Enter
6. Type 9,9 And Press Enter
7. Press Esc

The first step allows to activate the LINE command. (Learn more about the LINE command)

The second step allows to specify the starting point of the line and the same goes for next steps.

The last Step allows to Cancel the LINE command.

In AutoCAD stroking Esc (ESCAPE) allows to exit a command.

At this stage, you are not using the computer mouse, and you are require to pay close attention to the command windows while drawing. As we go, we will learn more about the command windows and how to use your mouse in AutoCAD.

## Exercise

Use the technique we have just learned to create the following.

Note you can start from any point.

### List of all current sessions of Learn AutoCAD Basics in 21 DAYS

DAY 1

You will learn how to use the coordinate system to create objects in AutoCAD.
DAY 2
Learn how to perfectly make use of the LINE command in AutoCAD, and acquire the mastery of this command.
You will be able to challenge yourself with a couple of AutoCAD exercises, and you will be taught step by step how to solve the exercises.
Learn how to play with angles in AutoCAD.
DAY 3
Learn how to create circles in AutoCAD using the CIRCLE command and master the UCS command.
The UCS will help you place objects appropriately in the drawing window while working on projects. It is important at this point to have mastered the coordinate system, and this one will further make you sink the DAY 1 into your brain.
DAY 4
You will have one more exercise that will help you practice with the UCS command.
On top of that, you will be learning the FILLET command and will have the opportunity to perhaps work with the POLAR TRACKING Mode.
In this session you will also be pushed to use the MIDPOINT feature of the Object Snap Setting
DAY 5
You will learn how to play with the POLYGON command in AutoCAD. Creating Circumscribed around a circle and inscribed in a circle polygons with different number of sides.
You will also have another opportunity to practice the CIRCLE, the LINE command and the TRIM command in AutoCAD
DAY 6
You will learn how to use the ARRAY command to solve complex problems while working with AutoCAD.
In this session, you will make heavy use of the CIRCLE command and the FILLET command, but you will have to do all this after getting the ARRAY command right.
DAY 7
You will learn how to use the OFFSET command appropriately in AutoCAD.
It is to be noted that previously earned knowledge will be crucially needed to be able to keep up moving forward in this series. That being said, you will need all you've learned earlier, not to mention the TRIM command that is an unavoidable command when working on a project in AutoCAD.
DAY 8
Learn how to make use of the QUADRANT option of the Object Snap Settings.
A complex image will be provided with this session, and you will have to use commands that you might find appropriate to solve different issues that will arise. A skeleton image will be provided to help you Analyze the exercise.
DAY 9
Time to play harder with that UCS command
You will also have to learn how to use the CHAMFER command with in this session.
Although the exercise provided is very basic, it will allow better understanding of the UCS in AutoCAD.
The Option Diameter of the CIRCLE command may be used as well if you would not like to use a calculator or your brain to calculate dimensions.
DAY 10
Here a little bit of all we've learned earlier will be needed.
An image is provided and you will be required to use a sense of analysis to be able to complete it.
The other aim in this exercise is to push you use the MIRROR command in AutoCAD, but you can well avoid using it.
You can decide to use the UCS command here if you like.
DAY 11
In DAY 10, we gave you the choice to use the MIRROR command or not. This session will restrict that choice. The way information are provided here will force the use of the MIRROR command.
You will also have to learn how to use the ELLIPSE command in AutoCAD and learn how to bend it with a given angle.
You will also be shown how to use the POLAR tracking mode to work in AutoCAD.
DAY 12
Here is one the most difficult session.
You will learn how to use a trick to create an array around an ELLIPSE in AutoCAD.
A complex image is provided and you are shown how you can proceed if you want to trick AutoCAD to construct an ELLIPSE ARRAY since there is no command doing this in AutoCAD yet.
You will also be taught how to create a perfect star in AutoCAD.
DAY 13
If you have learned how to proper use the Polar Tracking mode, this one will be a piece of cake. Nevertheless, it will help you make sure you have mastered it.
You will be forced to use the Tan Tan Radius option of the CIRCLE command.
The ROTATION command might also be useful to you if you want to avoid making use of the Polar Tracking Mode
DAY 14
Here is a session that will show you there is not only commands that do the job for you in AutoCAD.
You will have to learn how to read a design and be able to easily replicate it using commands you will choose to make use of without being told or shown.
The ROTATE command will be needed here.
DAY 15
Bringing difficulties a step up to make you make use of Basic AutoCAD commands.
In this Session, you are not taught what to do, but you are rather given an assignment that will make you use the command you have already made use of.
A skeleton image will be provided to help you.
DAY 16
Here is a place where you will be pushed to asses the knowledge you've earned in DAY 12.
If you have not mastered what was shown in DAY 11, this one will not be an easy one to accomplish.
You will have to know how to use the MIRROR command, and know how to manipulate lines to come out with happy with this relatively complex design.
DAY 17
Here you will learn how to work on complex and bushy project.
You need to be able to use the zooming and panning here to perform this one with success.
There is nothing new to learn, but assessment to be done on what you have learned.
The Tan Tan Radius option of the CIRCLE command will be highly needed in this session.
DAY 18
Learn how to combine AutoCAD commands while working on a project.
The project itself has nothing you have not made use of in previous sessions.
Here is one more session that will bring challenges, and push you to use the OFFSET, CIRCLE and ROTATE commands.
DAY 19
Here you will learn how to further work with the ROTATE command in AutoCAD. You are given a 2D representation of an elbow, and you will have to replicate the image given all its dimensions.
This session is more about being able to choose a way to go for solving difficult 2D design issues in AutoCAD and choosing the most appropriate commands to solve those difficulties.
Learn the basics of HATCHING in AutoCAD.
DAY 20
Not a complex project, but a project with too many details.
Here you will learn how to manage a project with many details.
At this point you can start working with ANNOTATION and train yourself to Annotate using past exercises.
DAY 21
All AutoCAD basics has practically been learned at this point.
Here is a session where you will learn how to Annotate an object in AutoCAD.
Learn the Basics using the DIMSTYLE command and learn how to use MTEXT command.

Hi
I know nothing about cad drawring and am going no where at the moment I’ve been looking at cad for a will now but cant get my head about it. The only other subject that has xyz is my milling machine there must be a simpler drawring methed
John

• What can we help you with? Have you got a CAD software you are trying to master? What are you struggling with?

• erick

I am using autocad 2016 and I cant seem to figure the coordinate point system out

• You might need to Zoom after following the example above to really see what is happening.

Click on the area shown on the image below after following the example in this post. Let me know if it helped.

• Lakshay Bahl

I am using AutoCAD 2016.
While drawing a line, I can only specify co-ordinates of the next point with respect to the current point and not w.r.t. to the origin.

• To enter absolute coordinates relative to the World Coordinate System (WCS), enter * as the prefix to the coordinates.

You can read more about it here

• basbob

I can’t do this at all either – I have the same problem as Lakshay and if I use • before the co-ordinate nothing happens. Please hep me too

• Thanks for sharing…that will surely help more than one here.

• venkat

please tell about coordinate system i am not got it

• venkat

i am not understand that coordinate system

• Try to go through it once more because I think it has been already quite well explained or try the video-sessions, it is more easy to follow.
You can as well move forward, and come back when you’ve completed the rest of the exercises, may be it feels less difficult then.

• Maryam

This is what i have!
Could you help me…

• Try putting the symbol # before entering the info for each point.

• Onur Inal

This is my first try about Autocad, maybe it just has a simple solution but I really couldn’t do it. When I click Line button on the pannel, it says ”Line Specify first point” at the command panel it’s okey till here. But the matter is when I try to type coordinates it always take line from origin never begin from (9,9) coordinate numbers. I couldn’t solve this please help me if there is something wrong about me.(Autocad 2017)

• This is not the origin. Try zooming out while maintaining the cursor on that point, you will eventually notice that it is not the origin.

• Pipandleo

I have no idea what I’m doing wrong but the shape I’m getting does not resemble that above. I seem to be having the same problems as everyone else here. I’m using the 2017 student version and I can’t even get a simple square when following directions. I’m doing exactly what I’m told but it just isn’t working out.

• Move to the next session if possible. We are looking into this and will bring an update to the article in the coming days.

• Batuhan Suiçmez

It seems like this site will be very very helpfull I realy appreciate you all.Thanks for the first day.

• Thanks for stopping by. 🙂

• Joel John Elias

is there any way to avoid having to enter # before every set of coordinates?
p.s.: Merry Christmas

• Joel John Elias

also, is it possible to display the coordinates as well?
