Upload a watertight STL model and the system computes a two-part mold around it — complete with guide pins, a sprue, and a vent, ready for printing or CNC milling.
Generates a separate piece for the object's hollow interior, offset inward by a wall thickness — useful when only a shell should be cast, not a solid.
For wrap-around surface patterns a plain 2-part split can't clear. Splits the mold into N wedges around the Z axis instead of top/bottom. Not combinable with vessel mode, tray mode, bolt holes, or side cores.
