We introduce a new geometry manipulator, a tool for 2D geometrical object manipulations in drawing packages. The manipulator is an extended combination of two standard approaches. We performed an experiment, where users tested three types of manipulator. We evaluated the manipulators on perceived flexibility, efficiency of use, and subjective satisfaction. Our new manipulator scored high on all aspects. Keywords Drawing package, geometric transformation, geometry manipulator
