20 Days of 2D AutoCAD exercises #11

Welcome to today's play. Here is a simple figure that will serve us today.

Again, we will be using tricks we have learned and leaning new tricks as well. I would love to show you the ARRAY command today.


I will recommend you look at how to create ARRAYS in AutoCAD. Here, we will create a polar Array with 3 elements. Basically, we have to draw one element, and use the ARRAY command to get other elements.

All 3 legs of the design are forming 120 degrees with one another, yes, they are uniformly placed in a circular arrangement.

Step 1

Draw the figure below.


Step 2

Use the ARRAY command to create a polar Array. A is the center of your array.


Step 3

Use the FILLET command to get H, P and Q. The raidius is 30.


Step 4

Draw the last piece of object, use the ARRAY command again to get the others around the whole design. Use the same center as you did in Step 2


Pretty easy right!?

See you on the next 2D exercise, don't forget to like ans share.



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.

    Doing a polar array with the centre circle won’t that create 3 circles on top of each other?

    This could cause problem if this was a more complicated drawing.

  • Micky

    Hi there, I’m having a bit of trouble doing the fillet. AutoCAD is not letting me select the straight lines? Each time I try to select a line, the whole array is selected as one. I also cannot trim lines. Can you help me please? Thanks

    • Antone

      It is hard to see what you are doing wrong. The array should not be a single object, not sure how you can select it all with a click.
      Try using the EXPLODE command on your array, and try again to see if it helps. http://www.ncsu.edu/project/graphicscourse/gc/acadtut/explode3.html

      • Kahleb

        I’m having a similar problem, I cannot figure out how you selected individual lines as my array is a solid object also.. It’s doubtful you will see this as this was a year ago now but figures I’d try. Thanks for any help, great series of practice work!

        • Matt

          I was just having this issue and Antone’s explode command worked to break up my array into segments, allowed the fillet to work as well as trimming

    • Areeb Ahmad

      After ARRAY command you need to use EXPLODE command (to tell AutoCAD that these 3 cones are now different entities) and then use FILLET command. 🙂

  • do713

    Wouldn’t it be easier to start from drawing what’s on step four (with the drawing in step 1 as a guide) and then apply array? It seemed way easier to me. Anyway, thanks for great exercises

  • Б. Батзаяа

    hello I CANT use Fillet command. Help me anybody?
