Driving a simulation in a helix?

    Any one with any ideas, ive tried mating helix surface to vertex... etc but
    always if the mate is accepted then the model is fully or over defined, the
    problem is animating a screw.

    TIA,

    Also, If your trying to animate a screw turning into or out of a hole you
    should be able to rotate it and move it simultaneously paying attention to
    the thread pitch to accurately simulate the helical thread. (That's how
    our lathe does it :))

  4. try making a helical surface that has the same pitch but square to the axis
    the problem may be in part because a helical thread is angled to the axis
    just a guess.....Just tried it with a simple example. I didn't animate it
    but the mate worked and if I moved the helix radially it moved as expected.

    ....it seems that I had two problems, one is that the mate is solved for the
    entire length of the surface/vertex and as I am using a 3 deg taper the mate
    was failing at one extreme, the other more bazaar is that surface that I was
    grabbing to drag the screw seems to play a big part in the performance, the
    larger the surface the slower more erratic the performance, the best being a
    vertex on the rotational axis, the model will behave when manually dragging
    but will not respond in the animator or when attempting to drive the part
    with distance mates. The model is very processor intensive and seems to bog
    down easily. The faster the helix the better the performance but this may
    just perception.

    Best, JAG

  6. Maybe you can use A radial simulation to get a base animation and modify the
    schedule to what you want. When I was dragging the helical surface that I
    had created it wouldn't move unless I mimicked the rotation that it needed
    to do. Anyway good luck with the project.
