Profil on a Spline

EugenEugen Member Posts: 16 PRO
Hello guys and girls

I start the profil in an angle of 90° and want to finish it in an angle of maybe 0°. How to do this?

    Add sections to both ends, Loft with a path instead of Sweep.

    This method uses loft

    It does NOT require any intermediary profiles

    This profile rotates 1/4 turn from end to end

    The twist happens all along the path at a constant rate of rotation from end to end

    The twist is built around the 3D Spiral FS

    Never used it on anything before. Didn't bother reading anything

    Played with it for a few minutes and was able to pick it up -- because of the well designed interface !!

    Like the ability to insert and easily edit. Great tool.

    You want a twist of 1/4 revolution (90°)

    The 3D Spiral featurescript will only do whole number revolutions
    So I have to use a LEAD IN to chew up 3/4 of a revolution

    So the straight lead in needs to be 3 times longer than the freeform spline
    3 parts of straight line to 1 part of freeform spline

    Another way to say it is, for the one revolution of the spirals ------
    3/4 of the length needs to be in the straight line
    1/4 of the length needs to be in the freeform spline

    This means that there will only be 1/4 of a revolution left for the spirals by the time they get to the freeform spline
