Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures include, in at least one aspect, a fully automatic method of converting a generative design into an editable, watertight B-Rep by leveraging the generative solver input and representation to: (1) embed the exact input solid boundary surfaces where the design coincides with the input, (2) approximate everywhere else the design boundary with globally smooth, editable 'organic' surfaces, and (3) join all surfaces to form a generative design output B-Rep.

Conversion of generative design geometry to editable and watertight boundary representation in computer aided design

A method, apparatus, and system provide the ability to conduct a dynamic simulation in a computer-aided design (CAD) application. A CAD model is acquired on a server. On the server, a proxy object is created for the CAD model. The proxy object is a voxel-based representation of the CAD model and fully encompasses a simulation mesh of the CAD model. The proxy object is transmitted to the client. The transmitted proxy object includes extents of a voxel domain, of the voxel-based representation, in three (3) directions, minimum and maximum coordinates in each of the three directions, and a number of voxel divisions in the three directions. the proxy object is processed on the client and enables dynamic interactive rendering operations. The simulation mesh is processed on the server and the proxy object on the client is replaced with a real polygonal rendering from the simulation mesh.

Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures, which can be built using various manufacturing systems and techniques, include, in one aspect, a method including: obtaining a design space for a modeled object, design criteria, an in-use load case, one or more materials specifications, and one or more safety factors; producing at least one generatively designed 3D topology of the modeled object, including, starting from an initial design, generating a first design in accordance with a first target defined by a first of the specifications or of the safety factors, and starting from the first design or an intermediate design generated between the initial design and the first design, generating a second design in accordance with a second target defined by a second of the specifications or of the safety factors; and providing both the first design and the second design.
