# 20 Days of 2D AutoCAD exercises #4

Welcome to Day #4 of this series of 2D AutoCAD exercises.

**Before we move on with our tutorial – we strongly recommend getting our 100 CAD Exercises eBOOK !**

**Click below to see what's inside…**

**In this CAD tutorial we have a simple image to replicate using AutoCAD.**

All dimensions are given.

If the drawing above is confusing, use the following one, where the image to draw is the one in the red color.

If you followed since Day #1, You should have no problem drawing this. However, the new part in this excercises consists of the place where you need to draw a line knowing its **inclination** and its **distance**. This is shown below:

In this figure, we have a line of length 4.6 and this same line is at an angle of 49 degrees with the another line of length 2.

To achieve this drawing with AutoCAD, you should first draw the line of length 2, which you should know how to do. Afterwards, start a new line at point A, type **@4.6<41** and hit the ENTER key on your keyboard. The command is defined as 4.6 being the length and 41 being the angle in degrees.

Are you wondering why 41 degrees when it is stated as 49 in the figure? AutoCAD counts angles in trigonometry form. Therefore, to find the right angle you must do the math, for example, 90 – 49 = 41.

In general, a figure is shown below on how AutoCAD counts angles.

This brings us to the end of today's exercise, please like, share and comment.

See you on day #5 of learning AutoCAD.

The whole series | |
---|---|

AutoCAD Exercises #1 | Drawing 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 #2 | Learning how to draw straight lines with definite dimensions. Basic concept for daily use while working with AutoCAD |

AutoCAD Exercises #3 | Learning the use of OSNAP and using skills you gained to design a more complex 2D. |

AutoCAD Exercises #4 | Using 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 #5 | FILLET command and the use of OSNAP. Learning how to place object. Learning how to use center points. |

AutoCAD Exercises #6 | CHAMFER command. Using the CHAMFER command and leaning more about the command window. |

AutoCAD Exercises #7 | how 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 #8 | Playing 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 #9 | Clear 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 #10 | Tricky 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 #11 | Concrete 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 #12 | We 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 #13 | MIRROR 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 #14 | Create 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 #15 | Using 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 #16 | This 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 #17 | Revision 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 #18 | Learning 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 #19 | Learning 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 #20 | Exam 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. |
