摘要： The present disclosure features methods and systems for direct-parametric interoperability in computer-aided design. Two approaches for developing three-dimensional designs are currently widely used: direct and parametric computer-aided design (CAD) modeling. To combine advantages of both approaches, in one aspect of the present invention, a direct modeling user interface is used for editing a model, allowing intuitive and easy manipulation of geometry, and a parametric geometry engine interprets these manipulations as history-based features to create a construction recipe. Thus, the underlying architecture of the model remains parametric, even though the user may not realize that history and associative relationships are being created and modified during every manipulation. Accordingly, the present invention provides the intuitive WYSIWYG editing of direct CAD modeling, while retaining the powerful features and regenerative capabilities of parametric modelers.

摘要： The present disclosure features methods and systems for enforcing parametric constraints in a direct modeling interface in computer-aided design (CAD). A parametric geometry engine of a CAD application may compare an attempted edit to a feature in a direct modeling user interface of the CAD application to an existing constraint created in a parametric modeling user interface, and, in one embodiment, prevent the user from completing the edit. In other embodiments, the parametric geometry engine may present a dialog box to the user and allow them to reject the edit, override or delete the constraint, modify the constraint, or take other actions as appropriate. In still other embodiments, the parametric geometry engine may allow one user to edit the feature, but not another user. Thus, parametric constraints and permissions-based ownership of entities may be enforced in a direct modeling user interface.
摘要翻译：本公开的特征在于在计算机辅助设计（CAD）中的直接建模界面中执行参数约束的方法和系统。 CAD应用程序的参数几何引擎可将尝试的编辑与CAD应用程序的直接建模用户界面中的特征与参数建模用户界面中创建的现有约束进行比较，并且在一个实施例中，阻止用户完成编辑。在其他实施例中，参数几何引擎可以向用户呈现对话框，并允许它们拒绝编辑，覆盖或删除约束，修改约束或适当地采取其他动作。在其他实施例中，参数几何引擎可以允许一个用户编辑该特征，但不允许另一个用户。因此，可以在直接建模用户界面中强制实体的参数约束和基于权限的所有权。

摘要： The present invention provides a method, system, and instructions stored on a computer readable storage medium that resolve interference between surfaces in a modeling environment, such as a CAD environment. Further, exemplary embodiments of the present invention may modify the surfaces of a model to ensure that parts of the model constitute a solid body. In exemplary embodiments, when the manipulation of a first surface or set of surfaces causes interference with a second surface or set of surfaces, the topologies of the surfaces are modified to account for the interference. The individual surfaces involved in the intersection may be treated as a merged surface or set of surfaces having a single topology, surface area, and volume. If an ambiguity arises whereby more than one option exists for resolving the interference or providing a solid body, the modeling environment may provide multiple potential solutions to a user, and allow the user to select from among the solutions.
