Draw Circles
You can create circles in several ways. The default method is to specify the
center and the radius. AutoCAD provides three other ways to draw a circle,
as shown in the illustration.
Draw a Circle Tangent to Other Objects
The tangent point is a point where an object touches another object without
intersecting it. To create a circle that is tangent to other objects, select the
objects and then specify the radius of the circle. In the illustrations below, the
bold circle is the one being drawn, and points 1 and 2 select the objects to
which it is tangent.
To create a circle tangent at three points, set running object snaps (
OSNAP) to
Tangent and use the three-point method to create the circle.
