Moving object using the object frame, with a [Cen]ter snap.

The function move don't make the trick?
Select the line by it center and move it to the snap center of the arc :)
It's not speedy and easy? Object frame must be not a dogma :D

A shortcut is possible to call/uncall the "Object frame selection"?
