Abstract: Methods and computer-based systems analyze designs for casting parts from molds. An input including that defines a part to be cast is received, including a mold design for the part and/or a set of graphical triangles that visually represent the part. Based on the received design, an undercut region and associated parting line location are determined. The orientation or directionality of the part for the casting may further be determined. Hotspots in the design are further identified. Based on these identified features, feeder dimensions and position are determined for the part to be cast. Directional solidification areas are further identified, and the identified characteristics are output or used to determine improved casting parameter. The part may then be poured into a casting using a mold with the determined characteristics.
