Use Transform Coordinate Center
 
 
 
Command entry:Main toolbar (Use Transform Coordinate Center), on Use Center flyout

The Use Transform Coordinate Center button, available from the Use Center flyout, lets you enable rotation or scaling of an object or objects around the center of the current coordinate system. When you designate another object as the coordinate system with the Pick function (see Specifying a Reference Coordinate System), the coordinate center is the location of that object's pivot.

The axis tripod shows the center that is currently being used.

NoteThe transformation center mode is set on a transform-by-transform basis, so select the transform before you select the center mode. If you do not want the center setting to change, turn on Customize menu Preferences General tab Reference Coordinate System group Constant.
