LEARN AUTOCAD BASICS

We will use the image below, and try learning all things we need to learn to be able to create something similar using AutoCAD.

We’ve learned a little how to use the coordinate system to create lines in AutoCAD. In this Session, we will forget a little about the Cartesian coordinate system.

It is true that using the Cartesian coordinate system we could draw lines with specified dimension, but this method is more convenient and is the one you will be making use of in the future.

Read more about how you can create lines and play with their angle

EXECUTION

To create the image above

STEP 1

Draw the line of 80 units

Click on LINE

Specify the first point

Make sure the ORTHO mode is ON, Move your mouse rightward, type 80 and Press Enter

Press Esc

STEP 2

Start the second line from the first point of the 80 units line, and draw the second line with an inclination angle of 58 degrees.

STEP 3

Draw the third line. It is a straight horizontal line.

STEP 4

All you have to do now is to create a line from the 2 open points shown on the figure in step 3.

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 theseAutoCAD 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 a 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.
