Abstract: Methods and systems are disclosed for a computer aided design system for designing multilevel lattice structures. A coarse lattice module defines a coarse lattice of balls connected by beams within a first boundary. A fine lattice module defines a fine lattice of balls connected by beams within a second boundary. The coarse lattice and the fine lattice have intersecting regions. A trimming module constructs a multilevel lattice structure according to a trimming operation based on the intersecting regions.

Abstract: Systems and methods for support structures for additive manufacturing of solid models. A method includes receiving a solid model, for a physical object to be manufactured, that includes a plurality of boundary representation surfaces. The method includes analyzing the b-rep surfaces to generate point samples for potential support locations. The method includes clustering points on the solid model, corresponding to at least some of the point samples, to create support locations. The method includes generating column supports in the solid model that connect to the original solid model at the support locations. The method includes storing the solid model, including the column supports.

Abstract: Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a solid model. The method includes analyzing the solid model to determine a suggested orientation that minimizes a build height or minimizes a support volume. The method includes displaying and saving the suggested orientation.
