Introduction To Auto desk AutoCAD | DAY 8

Learn AutoCAD basics: DAY 8

We hope your assessing skill has improved, meaning you are more able to judge the difficulty of an exercise just by looking at it.

In this post, we are going to keep on using basic AutoCAD commands and focus more on how to combine their use to accomplish a specific task.

LEARNING AUTOCAD BASICS

The following are the images we are going to be using today.

EXECUTION

Start by creating the following.

The first object you should create is the red circle. Then make sure the QUADRANT mode is activated in the Object snap settings, this will help you snap the center of those big circles at the point A.

(Right click on 1 and tick 2)

After proper trimming you will end up with the following image

Use the OFFSET command on the red part to obtain the following. OFFSET distance = 12.5 units

Draw a line from the two openings of the object, and create a circle using the middle point B of the line you have just created.

We have not talked about the small circles 30 and 60 degrees away from the vertical. Using techniques we have used to create objects in previous DAYS, those should not be a problem.

Introduction To Auto desk AutoCAD | DAY 1

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.

Note you can start from any point.
