Hi Mala,

I can't be sure since i didn't see the file to test with, but your result there looks like what would happen if you use Flow to transform just the profile curves and then did a Loft on the transformed profile curves.

Instead you should generate the Loft from the initial profile curves, and you want to flow the lofted object.
