Practice Question 1

Draw the below diagram in AutoCAD

Practice Question 1

Note: Try to create the figure yourself first. If you are unable to create, follow the below steps.
The method to create a figure may involve different commands from person to person. We are required to check if the output figure and dimensions are correct or not.

Solution:

Since the values of dimensions are greater, we need to specify the limits first.

The steps to set the limits are listed below:

  1. Type LIMITS on the command line or command prompt.
  2. Press Enter or spacebar.
  3. Write the coordinates of the lower-left corner. For example, (0, 0).
  4. Press Enter.
  5. Write the coordinates of the upper-right corner. For example, (150, 150). You can adjust the limits according to the choice.
  6. Press Enter.
  7. Write Z. Here, Z signifies Zoom.
  8. Press Enter.
  9. Write E. Here, E signifies Extend.
  10. Press Enter.

Note: Here, the value of coordinates will be measured from the origin of the UCS.
We can also draw a figure without using UCS. It depends on our choice.

We can now start our drawing.

The steps to create above figure in AutoCAD are listed below:

  1. Place the UCS at the center of the viewport. The UCS looks like the below image:
    Practice Question 1
    We can place it anywhere in the viewport according to our requirements.
  2. Type Rec or Rectangle on the command line.
  3. Press Enter.
  4. Click on the first corner point on the origin of the UCS. We can also type 0, 0.
  5. Specify the length and breadth of the rectangle in the form of @length, width. Here, we will create a large rectangle of dimension 105 x 60. Example - @105, 60.
  6. Press Enter.
  7. Type L or line on the command line and press Enter.
  8. Type the coordinate 35, 0 and press Enter.
  9. Type the coordinate 35, 60 and press Enter.
  10. Press Enter.
    The line formed using the above steps will look like the below image:

  11. Type L or line on the command line and press Enter.
  12. Type the coordinate 70, 0 and press Enter.
  13. Type the coordinate 70, 60 and press Enter.
  14. Press Enter.
  15. Now, the figure will look like the given image:
    Practice Question 1
    Now, we have to create two triangles. Some lines will be declared using relative coordinates (with @) because the value is not specified from the origin.
  16. Type L or line on the command line and press Enter.
  17. Type the coordinate 0, 60 and press Enter.
  18. Type the coordinate @35<60 and press Enter.
  19. Type the coordinate 35, 60 and press Enter.
  20. Press Enter.
    For another triangle:
  21. Type L or line on the command line and press Enter.
  22. Type the coordinate 70, 0 and press Enter.
  23. Type the coordinate @35<-60 and press Enter. We can also type @35<300 because the angles are measured in counter- clockwise direction.
  24. Type the coordinates 105, 0 and press Enter.
  25. Press Enter.
    Now, the figure will look like the given image:
