Why can't I do a swept with two guide curves when having a circle for a profile in SW?

Tutorial as required

  1. Step 1:

    First you draw a profile on a top plane. A profile is a circle. On the right plane you can draw a 1st guide curve and use a pierce as a reference between the guide curve and a profile. On the front plane draw a 2nd guide curve and use the same reference as you did with the first. Than draw a path which is a straight line going from the center of the circle (see the picture)

  2. Step 2:

    Activate the sweep feature. Chose a circle as a profile, chose a straight line as a path, open the guide curve section and select the guide curves.

  3. Step 3:

    As you can see, as soon as you select 2nd guide curve the preview disappears, which means that something is wrong.

  4. Step 4:

    When selecting only one of these guide curves we get the preview.

  5. Step 5:

    Than you must delete the circle. Circle is to rigid and you can only change his dimension with one guide curve with sweep feature. When deleting the circle you will notice the exclamation mark on the sketches in the design manager tree.

  6. Step 6:

    Edit those sketches and delete the pierce relations.

  7. Step 7:

    On the top plane draw a ellipse that has the same dimensions as the circle before. Basically start the ellipse from the start point of the path and end the ellipse on the start points of the guide curves.

  8. Step 8:

    than activate the sweep feature and do everything as before. When you select both guide curves you will see the preview.
