Learn AutoCAD basics: DAY 5

Hope we have providing some insights to you with this series of learning AutoCAD through exercises.

We previously worked on exercises that helped us master the following:

Learn with Videos instead

Today, we are going to continue learning and the object that will allow us do that is shown below.

As you can see the only added tools here is the POLYGON command which you will have to learn if you want to successfully replicate the image above.

Learning AutoCAD Basics

It is important to have you see the following.

learn-AutoCAD

It is important to understand that the two polygons do not have same characteristics. The Polygon on the left side of the image is a 6 side polygon circumscribed about a circle of R=20 and the Polygon on the right is a 5 side polygon inscribed in a circle of R=15. (illustrated on the image using the dashed red circle)

All fillet are R=10 units and remember that you need to learn how to create a polygon in AutoCAD before attempting to do this exercise.

A trick you can use

It is possible to use the FILLET command on two parallel lines.

Using all we have learned in previous sessions you should be able to come out of this one without any hassle.

hey! If you have any confusion about this, Just leave a comment below. Let me know what is confusing about this, I will make it clear for you

Learn AutoCAD basics
DAY 6
learn-AutoCAD-Basics-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.
Learn AutoCAD basics
DAY 7
learn-AutoCAD-Basics-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.
Learn AutoCAD basics
DAY 8
learn-AutoCAD-Basics-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.
Learn AutoCAD basics
DAY 9
learn-AutoCAD-Basics-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.
Learn AutoCAD basics
DAY 10
learn-AutoCAD-Basics-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.
Learn AutoCAD basics
DAY 11
learn-AutoCAD-Basics-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.
Learn AutoCAD basics
DAY 12
learn-AutoCAD-Basics-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.
Learn AutoCAD basics
DAY 13
learn-AutoCAD-Basics-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
Learn AutoCAD basics
DAY 14
learn-AutoCAD-Basics-day-14
Here is a session that will show you there is not only commands that do the job for you in AutoCAD.

Learn AutoCAD basics
DAY 15
learn-AutoCAD-Basics-day-15
Bringing difficulties a step up to make you make use of Basic AutoCAD commands.

    Hi there again, I have completed this tutorial but I have come across a mistake in which you may have put on your exercise. Correct me if I am wrong but the distance between the two circles which I have obtained was 59 not 79. In regards to the circle I have used your figures of 30R and 20R placing them at coordinates 30,30 and 129,30 respectively. Thanks

  • Hi John
    There is no mistake on the length between the two circles. You must be doing something wrong. I have no idea why you selected these coordinates for the centers of the 30R and 30R (30,30 and 129,30). Their centers can be anything, but they have to be on the same horizontal.
    If both circles are spaced from each other with 79 and these circles have respectively 30R and 20R, it means that the distance between the two centers is 79+30+20 which is 129.
