hi, designing a snap-fit enclosure for a small handheld sensor (approx. 60 x 40 x 20 mm), and I need to add structural ribs to the inner shell. The issue is the inner surface is slightly curved to accommodate an ergonomic grip, so the rib’s base isn’t flat. In Fusion 360, projecting the rib sketch onto the curved surface results in weird geometry when extruding, especially at the blend between the rib and wall. Is there a clean way to model ribs on a curved surface that still ensures proper draft for injection molding?
