Tutorial: How to get a helix on a spline/curve/polyline in Catia V5

The Helix curve function in Catia V5 only allows a helix on an axis or a line.
But there is a trick to create a helix on a spline/curve or polyline.

  1. Step 1:

    Create a curve and add a plane on the end of it.

  2. Step 2:

    Create a line on this plane.

  3. Step 3:

    Sweep the line on the curve use the settings shown in the picture.
    Reference surface is "default".

  4. Step 4:

    Create a second sweep - now the reference surface is the previously created sweep.
    Add a law with an end value that fits your desired result.
    Make sure the law type is "Linear".

  5. Step 5:

    Create a boundary with the settings shown in the picture.
    Surface edge is the outer edge of the second sweep.

  6. Step 6:

    Now your helix is finished and you can sweep a sketch on it to get your desired surface.
