conoidal
Like a funnel
Conoidal means shaped like or resembling a cone—tapering from a circular base to a point, or nearly so.
The term appears in technical contexts: geometry, architecture, and descriptions of shells or other natural forms.
A conoidal surface curves in one direction while remaining straight in another, like certain roof structures.
