      Well, three years later and I finally get around to it...

      I've got my design set up in MSPhysics (see my earlier post about one-handed brake lever design), but there always seems to be a 'barrier' around objects: I can't get them to touch, so the bottom lever never pivots. I can pivot it on its own, but can't get it to pivot using the upper lever blade.

      Everything is modelled to scale.

      I've searched, but I can't find anything about setting offsets for collision detection. Similarly nothing for limiting joint movement between certain angles (so objects don't spin freely). Can I do this?

      TIA

      Cheers,

      Tim

          Sure. What's the best way? Put it on the 3D Warehouse?

          Cheers,

            It's on 3D Warehouse as Ergopower OHBL

            Cheers,

              If you mark "Collision Wireframe", you can see how the parts touch each other (picture 1).
              You can fix this error by grouping the pieces separately (picture 2).
