Holes in scoop surface

I want to make holes in black surface just like blue surface has. How can I do it?

Hi Aram-n make a small plane, Gumball it - scaling, rotating - until it intersects your object with a good shape - use a shaded view or Intersect with History. When it looks good, use the plane to trim.


Thanks, Pascal.
