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.

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

Techniques for forming a complex shelled object are described. The shelling procedure does not merely combine two shelled objects into in single shelled object, but also integrates the two object with one another without destroying the integrity of either of the shelled objects.

Progressive shell operations

The invention includes computer instructions that operate to receive an indication of a modification of a geometry piece in a computer aided design (CAD) application. The geometry piece being of at least two segments and each of the two segments having a first length substantially equal to each other. The instructions further operate to automatically modify the two segments into at least two modified segments, where each of the two modified segments having a second length substantially equal to each other. The second length is based at least in part on the received indication of the modification of the geometry piece. As a result, maintaining segmentation of a geometry piece of a mechanical design is facilitated.
