This routine combines the Circle command's 3P option and the Tangent object snap.

This AutoCAD routine from Kent Cooper allows you to construct a circle tangent to three objects. It uses the Circle command's 3P option along with the Tangent object snap, but streamlines these into a nice command. You do not have to bother with Command line options or setting the osnap mode. If you miss a pick or select an unsupported object for tangency, the routine keeps prompting until you select a valid object. Load the LISP routine, then type in the command CT3. Start choosing supported objects such as a line, polyline segment, circle, leader segment, arc, dimension segment, etc., and a circle will be created upon the selection of the third entity.
