Abstract: A computing system may include a transition generation engine configured to access a computer-aided design (CAD) object comprising an external surface and an internal lattice structure represented through repeating unit cells of a lattice design, the internal lattice structure represented as a signed distance field (SDF). The transition generation engine may generate a transition structure for the CAD object within a transition distance from the external surface, including by applying a secondary SDF to modify a portion of the internal lattice structure within the transition distance from the external surface. The computing system may also include an object processing engine may be configured to process the CAD object comprising the transition structure (230) in support of physical manufacture of the CAD object.

Abstract: An event database table architecture includes an event table having information such as, for example, date, time, and activity. An event table has a field for identifying one of a plurality of participating tables, and a field for identifying a row within the identified participating table. A participant table has a field for identifying one of a plurality of participating tables, a second field for identifying a row within the identified participating table, a role code, and a row number identifying the event in the event table. Thus, each entry in the participant table relates to a unitary entry in the event table and also relates to a unitary row in one of the participating tables. Each event, participant, and act of participating can be accessed from any other related data item without accessing extraneous or unrelated data items.
