I made a surface by loft and then create offset and subdivide surface through divide domain, but notice a problem only when i tried interpolate points.
So i checked similar tipics and still haven’t any idea how to deal with this, i would appreciate for help.
Flatten would be yet another option.
here are some solutions you can check.
Hope it helps.
