# 20 Days of 2D AutoCAD exercises #1

Here is the first exercise of a series of 20 individual 2D exercises for AutoCAD. In this series, I will walk you through exercises with the aim of helping you learn how to draw in 2D using the software AutoCAD.

The learning process will be simple. We start from the end, meaning we will set specific goals and we will find how to use AutoCAD commands to meet such goals.

To begin, we will start by trying to draw this simple figure below. Too simple right? The objective here is to learn how to use the command window in AutoCAD in order to draw without using the mouse. This will help us have a first glimpse on how this window works.

We have 4 points and we have the coordinate of each of them. So, basically we have each starting point of our lines and each ending point.

AutoCAD draws lines using coordinates. To better explain, we put our figure in a system of coordinates in the image below in order to improve our understanding. If we consider a coordinate system formed by X, Y, this is how our exercise will fit in the system.

To draw this, open a new file in AutoCAD

1. Type “LINE”
2. Specify first point: 5,0
3. Specify next point or [Undo]: 10,0
4. Specify next point or [Undo]: 10,7
5. Specify next point or [Close/Undo]: 5,5
6. Specify next point or [Close/Undo]: 5,0
7. Hit the ENTER once more
8. Click on 8 (look at the figure below)

(The part in bold is what AutoCAD is asking you to enter. You will see those same words displayed in the command windows. You should enter are those coordinates, e.g. 5,0 -> 10,0 -> 10,7 and so on. However, remember after each step you need to validate your action by pressing the ENTER key on your keyboard)

There you go! We are done with creating the figure. You noticed how we are able to draw without using a mouse. It may be difficult for a newcomer but not impossible.

AutoCAD draws lines from one point to the other and starts the next line where the previous one ended. In step 7, we disabled the LINE command and at that step you can also press the ESC key instead of the ENTER key, it will serve the same purpose. Step 8 is just to zoom out completely so you may see what you have just drawn.

I hope you learned something in this exercise and take a look at AutoCAD Exercise Day #2. Feel free to drop a comment below if you have any questions. Also, make sure to check out below the 100 CAD Exercises eBook; it comes with 50 2D and 50 3D exercises that you can use to practice!

The whole series
AutoCAD Exercises #1Drawing your first piece of 2D using AutoCAD. Using LINE command and fixing your settings for a better user experience. Learning how to use coordinates and Using exclusively the command window to draw.
AutoCAD Exercises #2Learning how to draw straight lines with definite dimensions. Basic concept for daily use while working with AutoCAD
AutoCAD Exercises #3Learning the use of OSNAP and using skills you gained to design a more complex 2D.
AutoCAD Exercises #4Using some math and drawing lines with specific angles and dimensions. Learning the basic concept of angles in AutoCAD, and actually using the trick main while.
AutoCAD Exercises #5FILLET command and the use of OSNAP. Learning how to place object. Learning how to use center points.
AutoCAD Exercises #6CHAMFER command. Using the CHAMFER command and leaning more about the command window.
AutoCAD Exercises #7how to use HATCH in AutoCAD. You will need skills from Day #4 to have the exercise done, and you will learn how to actually use the HATCH command.
AutoCAD Exercises #8Playing with the TANGENT feature of the OSNAP. You will have a complex figure to replicate, and you will have to learn how the TANGENT feature of the OSNAP works. You will also have to learn a new trick on how to draw a circle using this very technique.
AutoCAD Exercises #9Clear description on how the ARC command works and a complex exercise to try the technique out. All instructions are given for you to easily assimilate the tutorial.
AutoCAD Exercises #10Tricky exercise. You will have to use all technique you have learned in previous exercises to accomplish this one. Hints are given. And an opportunity to ask questions is as well given
AutoCAD Exercises #11Concrete exercise where you will have to see advantages of learning the ARRAY command. A Polar Array is designed and some old techniques you must have learned from the beginning will be helpful.
AutoCAD Exercises #12We have more than an exercise, The aim is to force you to use the ARRAY command. A rectangular Array is to be created.
AutoCAD Exercises #13MIRROR command. The mirror command has not been used since the beginning. This exercise makes it impossible for you if you don't use the MIRROR command. Learning the concept of symmetry in AutoCAD
AutoCAD Exercises #14Create a layers and changing line type. Using the ROTATE command and the OFFSET command. Learning how to combine a set of techniques toward something definite.
AutoCAD Exercises #15Using the combination of all techniques learned so far to come to achieve a complex 2D AutoCAD exercise. Previous learned techniques will be needed in this session and a little bit of math too.
AutoCAD Exercises #16This is a nice AutoCAD exercise that will make you test what you have learned so far. It is testing you ability to combine all you know to get a quite tough exercise done. Of course, hints have been provided to help you get it done.
AutoCAD Exercises #17Revision exercise. Be ready to use your calculator. You will need a bit more of precision in this session. An emphasis has been made on the ROTATE command, OFFSET command and FILLET command in this exercise.
AutoCAD Exercises #18Learning how to draw a polygon in AutoCAD. Here is shown how you can easily construct perfect star in AutoCAD, you may want to convert it into a block for future use. A complex figure is provided as well to help you practice.
AutoCAD Exercises #19Learning how to construct a complex drawing using technique provided to you in previous sessions. This serves as a test, to see how far you have gone since the beginning of this series of exercises.
AutoCAD Exercises #20Exam Day. Grab your Exam eBook for free and come back to me with questions and suggestions on how to make this course easier to understand if possible.
