PDS:Circle By Three Points Tool
From OptiTexHelpEn
This tool is used to create a circle that passes through three points (or buttons, circles, dart tip, etc.). This is very handy when the points already exist, and it is hard to connect all of them with the Arc Tool. The circle created can be changed through the 'Circle Properties'
