Methods, systems, and apparatus, including medium-encoded computer program products, for facilitating editing of generative design geometry of physical structures, include a method including: receiving editable smooth surface(s), e.g., a T-Spline, constructed from a mesh obtained using a generative design process; instantiating a parametric feature recipe to connect the editable smooth surface(s) with input solid(s), wherein the parametric feature recipe includes an operation sequence that (i) converts the editable smooth surface(s) into boundary representation format and (ii) combines the boundary representation formatted smooth surface(s) with the input solid(s) to produce a watertight three dimensional model of an object; modifying the editable smooth surface(s) in response to input, while preventing disconnection of the editable smooth surface(s) from the input solid(s); updating a visualization thereof in a user interface; and performing the operation sequence of the parametric feature recipe to produce the watertight three dimensional model of the object.

Facilitated editing of generative design geometry in computer aided design user interface

A CAD system enables a designer to freely modify a model of a design without regenerating a history of the model, as in traditional parametric feature based modeling. The CAD system automatically determines whether the modifications to the model invalidate current features associated with the model and whether the modifications create new features that should be added to the model. Such a CAD system enables a designer to quickly edit designs and simultaneously preserve design intent without requiring the significant computational resources of historical based approaches that regenerate a geometry upon every edit made by a designer.

Method for validating features in a direct modeling paradigm

A method, system, apparatus, article of manufacture, and computer readable storage medium provide the ability to manage modifications to a solid model between different modeling applications. An original model created using a parametrically-based modeler is obtained. A modified version of the original model that was edited using a history-free modeler is obtained. The original model and the modified version are analyzed to determine differences between them. Based on the differences, a set of parametric-based treatments are determined that, when performed on the original model, affect changes that produce a parametrically-driven version that geometrically matches the modified version. One or more of the treatments are individually selected and applied to produce the parametrically-driven version.

Modifying a parametrically defined model with an explicit modeler

A computer implemented method, apparatus, system, article of manufacture, and computer readable storage medium provide the ability to position/manipulate an object in a computer drawing application. A drawing model having a snap option and a first zoom level is displayed. The snap option that enables a positioning of an object in alignment with grid lines by causing the object to automatically jump to an exact position when the object is moved to within a first snap distance of the exact position. A zoom operation changes the first zoom level to a second zoom level. Automatically, dynamically, and independently from additional user actions, the first snap distance is recalculated based on the second zoom level.
