2 ENTS allows you to create a circle tangent to two 
selected entities, with a specified radius.

Enter a value for the radius and press <Enter>, or accept
the default value in parentheses by pressing <Enter>.

Select the first tangent entity, near the point of 
tangency. If necessary, you can cancel the selection by 
choosing the BACK-UP option and selecting another entity.

Select the second tangent entity, near the point of
tangency.

An error message is displayed if a tangent circle cannot 
be created, e.g., because the selected entities are not
coplanar and you are in 3-D construction mode. You are
prompted to press <Enter> and to select a different 
entity as the first tangent entity.

In 2-D construction mode, the circle is created in the 
construction view, at the depth that is active when 
the second tangent entity is selected.

In 3-D construction mode, the circle is created in the 
plane of the selected entities.
