ещё есть скрипты на эту тему , например HK Magnet Tool by Henry Korol ( HawK)
This tool is designed to speed up polygon modeling( tweaking) in maya. It allows to move the points on the mesh in one click. The
points in fallof radius( larger circle) are moved proportionally from the cursors center( using defined falloff ),
the points that are in offset radius ( smallers circle) are moved with cursor. The vertexies are moved in a plane which is most
perpendicular to the current view direction ( The curren slide plane is printed in the output line).
