            4.2 Drawing Tangents to Two Circles
When drawing entities tangent to a circle, there are two locations that satisfy the condition of tangency. When using a CAD system, select a point close to the tangent location you intend.
4.23 Drawing Tangents to Two Circles
4.24 Tangency constraints for two identical sets of circles are shown in AutoCAD.
