Hollow Shapes

Model hollow and perforated geometry with OCCT in Bitbybit - hex grids, hole patterns and lattice panels cut into faces and solids. Perforation is a recurring problem in real products: ventilation panels, decorative screens, weight reduction, and acoustic surfaces all come down to generating a pattern of openings and subtracting it reliably. These worked examples cover building a hexagonal hive pattern flat and on a curved face, placing rectangular and circular holes across a surface, and the thickening step that turns a perforated face into a solid you can print or cut.
