    摘要： Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design with connectivity filtering during shape synthesis, include: a three-dimensional modeling program configured to provide disconnection detection, shape synthesis, and/or connectivity filtering during shape and/or topology optimization (116). The three-dimensional modeling program (116) can be an architecture, engineering and/or construction program (e.g., building information management program), a product design and/or manufacturing program (e.g., a CAM program), and/or a media and/or entertainment production program (e.g., an animation production program).

    摘要： Examples described herein provide a computer-implemented method that includes performing feature recognition and boundary-represented fitting for a given digital geometry representation to classify a geometric primitive and a freeform surface based on a fitting tolerance criteria. The method further includes parameterizing the geometric primitive and the freeform surface. The method further includes building an associative computer aided design (CAD) geometry using the parameterized geometric primitive and the parameterized freeform surface, wherein associativity is maintained between the digital geometry representation and the associative CAD geometry.

    摘要： A method preserves shapes in a solid model when distributing material during topological optimization. A 3D geometric model of a part having a boundary shape is received. The geometric model is pre-processed to produce a variable-void mesh and to produce a frozen mesh representing the boundary shape. The geometric model is apportioned into a plurality of voxels, and a density value is adjusted for each voxel according to an optimization process. An iso-surface mesh is extracted from the voxel data, and a mesh Boolean intersection is derived between the extracted iso-surface mesh and the variable-void mesh. A mesh Boolean union between the mesh Boolean intersection and the frozen mesh.
