-#X text 40 486 to make your own strucute :;
-#X text 59 546 put "tut_mass" object in the screen where you want

-#X text 58 658 create a "tut_link" object for each link you whant to

-#X text 59 694 connect them to the mass (link and masss as to be

-a system. It can be made if the link output (force output) is not conectet

-#X text 34 485 a single structure (mass and link) is oscilating without
