# Tan, Tan, Radius Circle Drawing In AutoCAD(Illustrated Expression)

In this article of Mechanical Base, we will show you about how to create circles that tangents to 2 objects in Autocad drawing scheme by entering a Radius value to it. In Mechanical Base, we expressed the whole commands of Autocad 2d, so you can learn the use of Autocad 2d by reading articles from Mechanical Base about Autocad’s drawing commands. This kind of circle drawing method is very useful to obtain circles that tangents to other drawing features. It is very hard to obtain this kind of circles without Tan, Tan, Radius circle command in Autocad.
