Something like this?
Create the profile and do a full “follow me” around a 36 segment circle (10 deg between segment ends)
Switch on Show hidden geometry,
Roatate the whole bowl 5 deg to align the centre of a column of segments to the red axis.
Push a line of segments on the red axis inwards the desired depth. You will have to do some cleanup and closing of faces afterwards.
Go left and right of the pushed in faces two columns, and delete the remainder of the bowl to leave you with the sunken portion between 2 raised portions. Again, close the sides in a make the shape watertight. Group and check with solid inspector.
Once it is a solid, select it and rotate a copy (Shift+rotate) around the center to line up the edges.
Immediately after the first rotate/copy, type “* 12” to repeat the rotate/copy and it will create the whole bowl.
Select all, and use the Solid tools “Outer shell” to join everything up into one solid.
This was done with SU8 Pro, and there’s probably way easier techniqes in the new version…dunno…too cheap to upgrade
