Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures include a method including: obtaining one or more design criteria for a modeled object; iteratively modifying a three dimensional shape of the modeled object in accordance with the one or more design criteria, wherein the iteratively modifying comprises regulating shape change velocities for an implicit surface representation of the three dimensional shape that exceed a reference velocity; and providing the three dimensional shape of the modeled object for use in manufacturing a physical structure corresponding to the modeled object using one or more computer-controlled manufacturing systems. Further, regulating the shape change velocities can include reducing the shape change velocities above the reference velocity in accordance with a function.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, facilitate creation and use of 3D models of objects with different material properties. In one aspect, a method includes specifying a continuous data format representation for a first property of an object and a discretized data format representation for a second property of the object, wherein the first property and the second property are different from each other; producing a 3D model of the object within a 3D space using the continuous and discretized data format representations, which overlap with each other in all three dimensions in at least a portion of the 3D space; and using at least one common access method into the 3D model of the object to obtain data from both the continuous and discretized data format representations, within the portion of the 3D space, to manufacture the object using one or more manufacturing processes.

Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures using data format conversion (e.g., of output(s) from generative design processes) and user interface techniques that facilitate the production of 3D models of physical structures that are readily usable with 2.5-axis subtractive manufacturing, include: modifying smooth curves, which have been fit to contours representing discrete height layers of an object, to facilitate the 2.5-axis subtractive manufacturing; preparing an editable model of the object using a parametric feature history, which includes a sketch feature, to combine extruded versions of the smooth curves to form a 3D model of the object in a boundary representation format; reshaping a subset of the smooth curves responsive to user input with respect to the sketch feature; and replaying the parametric feature history to reconstruct the 3D model of the object, as changed by the user input.

Abstract: Techniques and systems for computer aided design of physical structures using an object splitting design process that optimize manufacturing efficiency are described. A described techniques includes obtaining an input model of an initial object to be manufactured, the input model providing a 3D topology and shape for the object; determining, based on the 3D topology and shape, a 3D parting surface to split the initial object into separate objects, the parting surface intersects an inflection zone that is situated between up and down skin regions of the 3D topology and shape; and providing first and second 3D models of the separate objects in accordance with the 3D topology and shape and the parting surface, for use in manufacturing separate physical structures corresponding to the separate objects using one or more computer-controlled manufacturing systems, where after respective manufacturing, the physical structures are configured to be assembled to form a combined structure.
