Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures, where the 3D models of the physical structures are produced so as to facilitate 2.5-axis subtractive manufacturing, include: obtaining one or more design criteria and one or more boundary conditions, modifying a 3D shape of a modeled object in accordance with the one or more design criteria and the one or more boundary conditions, including employing geometry filtering or simulation results filtering in the iterative loop or inserting voids at locations selected using one or more shape skeleton lines, and providing the 3D shape of the modeled object for use in manufacturing the physical structure using one or more computer-controlled manufacturing systems that employ the 2.5-axis subtractive manufacturing process.

Computer aided generative design with filtering to facilitate 2.5-axis subtractive manufacturing processes

Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures using techniques that facilitate manufacturing, include: modifying a three dimensional shape, for which a corresponding physical structure is to be created using a manufacturing process, to produce a modified three dimensional shape; and providing the modified shape of the modeled object for use in manufacturing the physical structure using one or more computer-controlled manufacturing systems that employ the manufacturing process. The modifications can include, for each of two or more discrete layers of the three dimensional shape along a direction associated with the manufacturing process, extracting a two dimensional profile representation of the three dimensional shape in a current discrete layer, offsetting the two dimensional profile representation by an amount associated with the manufacturing process, and changing a next discrete layer using an offset two dimensional profile representation of the current discrete layer.

Computer aided design with geometry filtering to facilitate manufacturing

Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures using generative design processes, where the 3D models of the physical structures are produced so as to facilitate manufacturing of the physical structures using 2.5-axis subtractive manufacturing systems and techniques, include: obtaining a design space for an object to be manufactured, design criteria, and load case(s); iteratively modifying a generatively designed 3D shape of the modeled object, including generating 2D profile representations (corresponding to discrete layers) of an updated version of the 3D shape, extruding the 2D profile representations along the milling direction, and forming a next version of the 3D shape of the modeled object from a combination of the 3D representations produced by the extruding; and providing the generatively designed 3D shape of the modeled object for use in manufacturing the physical structure using a 2.5-axis subtractive manufacturing process.
