AutoCAD tutorial 06: Circles in AutoCAD

In this post we are going to learn and start drawing circles in AutoCAD. Time has come to move forward and learn more, I believe it is the right time to learn and see how to use AutoCAD to draw circles.

The CIRCLE command is an important and a frequently used command, you can judge by its location and its size.

Drawing circles in AutoCAD

Drawing an ordinary circle is quite easy in AutoCAD. All you have to do is

  1. Click on the CIRCLE icon (shown on the image above)
  2. Specify the center of the circle with a click in the drawing area
  3. Specify the radius of the circle with another click

Example

Drawing the circle above, we will

  1. Activate the CIRCLE command
  2. Specify the center of the circle
  3. Type 30 and hit ENTER

as simple as that.

Sometime the information you have about the circle you want to draw is neither the center of it nor its radius. This is where comes other option of the CIRCLE command.

Center Diameter

If you are using the this option to draw a circle, you will simply need to repeat what we did earlier with the only different that at step 3, you will have to enter the value of the Diameter of the circle instead of entering the value of radius.

2 points

This option help you draw a circle using two endpoints, where the 2 points will form the diameter of the circle.

To use this

  1. Activate the CIRCLE command
  2. Select the first point
  3. Select the second point

3 points

This works absolutely like the preceding one at the difference that instead of 2 points you have to indicate 3 points.
