Learn AutoCAD Basics: DAY 3

The following exercise forces us to use the TRIM and the CIRCLE command in AutoCAD.

You might benefit to learn how to use these commands beforehand.

Exercise

In the previous session, we learned how to use the LINE command. Those techniques will help you a great deal here.

Here is the rough image you should strive to reproduce.

Two circles and two Rectangles.

What is the easiest way to get to this?

  1. Create the big rectangle using the LINE command
  2. Use the Center on the top side of the triangle to create the two circles.

For step 2, you need to turn the Midpoint ON if you want to be able to find the center of that segment while creating the circle

Here is how to do it (right-click on 1 and tick 2)

Now you should be at the following point

Trim the big circle and Erase the top side of the rectangle

Now, all we need to do is create a small Rectangle. Given the dimensions above, if we consider that the left corner of the figure is at the point of coordinates (0,0), we need to start the small rectangle at the point of coordinates (10,15)

What we will do.

  1. Move the UCS to the left down corner of the figure
  2. Start the line at the point (10,15)

How to move the UCS to the left down corner of the figure

  1. Type UCS
  2. Select the point
  3. Move the cursor on the x-direction and click
  4. Move the cursor on the y-direction and click

This is what you are supposed to get

Notice the UCS

Now you can easily start the line at the point (10,15) and create the small rectangle.

Ups! a slight mistake happened while I was setting up this exercise which I’ve just noticed. Normally that 92° angle should be 90° allowing other methods to be used, just like on the image below (considered the angle is 90°), you would just have to create the little square and use its appropriate edge as the center of the circle.

With that being said, the only method is most probably UCS

Sorry, only two angles are right angles

Correct ! That angle to the right is slightly different from 90 degrees. I might consider redesigning this exercise though the focus point here is to use the UCS command.
