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 mesh geometry to editable and watertight boundary representation in computer aided design

Methods, systems, and apparatus for computer aided design of physical structures include: producing a quad parameterization computer model (including quad parameter domains) of a polygon mesh, where quad parameter domain(s) adjacent to a boundary curve interpolate the boundary curve; and forming a computer model of a three dimensional object by constructing locally refinable surface representation(s) from the quad parameterization computer model, refining a boundary of the locally refinable surface representation(s) to approximate the boundary curve within a first tolerance value set in accordance with a smallest dimension representable by a geometry modeling kernel, freezing control points of the locally refinable surface representation(s) at the boundary, and modifying remaining interior portions of the locally refinable surface representation(s) to approximate the polygon mesh within a second tolerance value that is at least an order of magnitude larger than the first tolerance value.

Conversion of mesh geometry to watertight boundary representation

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

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.

Conversion of geometry to boundary representation with facilitated editing for computer aided design and 2.5-axis subtractive manufacturing

Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures include: obtaining a first 3D model including a polygon mesh associated with one or more modelled solids, the one or more modelled solids being in a boundary representation format; producing from the polygon mesh a quad patch network that combines, using transfinite interpolation, the polygon mesh with one or more smooth boundary curves corresponding to the one or more modelled solids; defining one or more locally refinable smooth surface representations using the quad patch network as input and based at least in part on a smallest dimension representable by a geometry modeling kernel of a computer aided design program; and combining the one or more locally refinable smooth surface representations with the one or more modelled solids to form a second 3D model that is watertight at the one or more smooth boundary curves.
