Sweep 1 - Result missing

Hi All,

Still messing around with Sweep 1 …

So I’m doing Sweep 1 with 6 sets of circles and 1 rail; each set has 25 circles with different radius.
Ideally it should come out with 25 closed surfaces, but for some reasons it only gives me 20.

I also try graft, although it gives me 25 at the end but the sweep doesn’t follow the 6 sets of sections.

Anyone know about this?

Any one has an idea? Any comment is appreciates.
