Using the revolve tool, I made a cone, an Ice Cream, Part of the cherry on top, and the cookie.

Very funny tomy! That cookie is a BIG one! :)

I tried to make it flatter, but I didn’t know how!

use revolve to make a sphere,and then make a rectangele(big) and move it with the deformation(old manipulation) over it,until you have something like a cookie.glue them,and erase the rest but the ‘sphere calote’,in mathematical language
or draw a line on a zx plane(perpendicular on the grid),then make a arc between the two.split the arc with a perpendicular line starting from the middle of the line drawed earlier(named mediane) and revolve a half of the bow(is looking like a claw) on the mediane

I tried it, but when I made a rectangle, I couldn’t glue it.
