## How to draw circles in the drawing

To create circles, you can specify various combinations of center, radius, points on the circumference, and points on other objects.
You can create circles in several ways. The default method is to specify the center and the radius.

### Draw a circle by center and radius

Click Menu "Draw", and then choose "circle"
Specify the center point.
Enter a radius value, or specify a point.
### Draw a circle with two points

Create a circle based on two endpoints of the diameter.

Click Menu "Draw", and then choose "circle two points"
Specify the first point on diameter.
Enter a value, or specify a second end of diameter.
### Draw a circle with three points

Create a circle based on three points on the circumference.

Click Menu "Draw", and then choose "circle three points"
Specify the first point on circle.
Specify the second point on circle.
Specify the third point on circle.
### Draw a circle tangent to two objects

Create a circle with a specified radius and tangent to two objects.
Sometimes more than one circle matches the specified criteria. The program draws the circle of the specified radius whose tangent points are closest to the selected points.

Click Menu "Draw", and then choose "circle tangent-tangent-radius"
Input specify radius value
Select the first entity
Select the second entity
Input "I" or "C" to select inscribed circle or Circumscribed circle
### Draw a circle tangent to three objects.

Click Menu "Draw", and then choose "circle tangent-tangent-tangent"
Select the three entities
Input "I" or "C" to select inscribed circle or Circumscribed circle
