How to change a straight polyline segment to arc segment?

A - answer If you need to change a line segment in an existing 2D polyline into an arc segment, you will need to break the pline, draw an arc and then join the segments into a new polyline (in older AutoCAD versions).

Since AutoCAD 2011 and LT2011 you can just select the given polyline (to show grips) and in the given segment hover over its middle grip. After a while AutoCAD displays a context menu with the command "Convert to arc" (or vice-versa "Convert to line").
