Abstract: 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.

Abstract: A computer-implemented method and system automatically solves constraints in a computer-aided design (CAD) model. A CAD model of a real-world object capable of assuming various positions is constructed and a constraint solver process is initiated and executes while a user defines multiple positions of the CAD model. Input of data specified during a CAD design workflow is automatically input to the constraint solver process, and unknown variables are solved for as part of the CAD design workflow.

Abstract: A computer-implemented method automates motion of a computer-aided design (CAD) model. The CAD model represents a real-world object comprised of a number of parts. The part containing a user-specified entity is analyzed to collect data relevant to a motion study, for example, size data, location data, and material type data are collected. Based on the user-specified entity, parameters for automating motion are inferred and used to automate motion. The parameters include at least one of a part that is moved directly by a motor, a location on the part where the motor is mounted, a motor type, an axis of motion of the part, and a motion function indicating a change of motion over time.

Abstract: 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 distance field and to produce a frozen distance field 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 an iso-surface distance field is generated from the extracted iso-surface mesh. A distance field intersection is derived between the iso-surface distance field and the variable-void distance field. A distance field union is performed between the distance field intersection and the frozen distance field, and a result iso-surface mesh is produced from the distance field union.

Abstract: A computer-implemented method and system automatically adjusts the size of a rigid body model. The method and system construct a two-dimensional model or a three-dimensional model, where the model has one or more rigid bodies. The rigid bodies are converted into geometric primitives that represent a respective rigid body and enable the respective rigid body to resize. One or more of the primitives are constrained to one another. A solver process changes a size of at least one geometric primitive and a rigid body simulation process uses the resized primitive(s) as input.
