I made a vid of your 5 profile loft here: https://moi3d.com/forum/index.php?webtag=MOI&msg=11889.1

The 25 profiles have a couple sections that arent very good to add in. a size variation creates a weird result.

You'll want to revisit creating sections in the original app to check numbers. More isnt always better. It does give more finite control. But you have to be more precise in variations between sections
