Twisting Flat Bar challenge

Trying to do this with latest Brics Mech. but failing miserably. The intent is to create a flat bar section that's bent 90 degrees with a 6" radius. No problem except it has stay in contact with the tank outer diameter - twisting so to speak. Look at the drawings/snap shots maybe someone can give some nice tips please? The actual model is attached too if you dare to try it.

    Hello.

    There is no special command or function to achieve the required task.

    One way of working could be to create a loft.
    There are two drawbacks:

    • The result is approximative.
    • The result is not parametric.

    The loft could use the two existing sections.
    One of them needs to be redrawn as polyline.

    Further, some guides would be needed, to make sure the resulting solid wraps around the cylinder.

    The guides can be created as splines.

    If you want to experiment with this approach, I attached the model where I tested it.

    Virgil, thanks so much! That's exactly what I was trying to do and it doesn't have to be parametric. Could you please outline the steps you took? I see the splines but they're straight, I don't understand how you got it to revolve.
