      how can i combine 2 or more joints like a motor and a piston or isn't it possible?

      example: a cube spins and can go up and down while spinning

        Hey!
        I don't think it works just with a motor and piston conected to a wheel.
        But if you group a motorjoint together with a box, and then connect the piston to the motor-box-group, then it will work.
        Here is a skp-file with a simple example:

        wheel and piston.skp

        P.S. if you don't want to se the box just right-click and hide it...

        hope this is to some help.

            Yes.
            Go in to the group with the box and motor, then right-click on the box --> SketchyPhysics --> State: ---> then ether "ignore" or "nocollision", it dosn't matter right now.

            And if you don't want to se the box after this ignore stage, just "hide" it under right-click-menu.

            /hpnisse

            PS. More info about ignore and nocollision state:

            Nocollison: http://sketchyphysics.wikia.com/wiki/NoCollision
