# Learn AutoCAD Basics: DAY 1

Welcome to the inaugural installment of our series: “Mastering AutoCAD Basics in 21 Days.”

Throughout this series, we’ll break down 21 CAD exercises into individual posts. By the end of this journey, you’ll possess the fundamental knowledge of AutoCAD 2D, empowering you to tackle complex projects with confidence.

Let’s begin with the essentials for Day 1. It’s crucial to familiarize yourself with these commands before proceeding further. If you’re confident in your ability to navigate the upcoming content independently, you can skip this step and continue reading below.

## Coordinate system

Within AutoCAD, the Drawing Area consists of a sheet where each location possesses distinct coordinates represented by x, y, and z.

As we exclusively focus on 2D work in this series, the z component of the coordinate system becomes irrelevant.

Examining the image below, you’ll observe that each corner of the figure is associated with coordinates.

Though it is true that you probably won’t 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 attempt to recreate the earlier image using the coordinate system and the command window. The process is straightforward – the idea is to utilize the four points to draw the quadrilateral.

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 second step allows specifying the starting point of the line and the same goes for next steps.

The last Step allows canceling the LINE command.

In AutoCAD stroking Esc (ESCAPE) allows exiting a command.

At this stage, you are not using the computer mouse, and you are required 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.

If you find any aspect confusing, feel free to leave a comment below. I have no problem providing further clarification.

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

2. To avoid confusion in doing the exercise, the Dynamic Input must first be disabled like what was suggested before drawing the quadrilateral. Please try and see the result.

3. i’m using AutoCAD 2018, I am able to the exercise perfectly, but the diagram is not being centered in the work space area. How do i center it

4. Click on the wheel on your mouse and hold. drag it to the center.
