摘要： This invention presents a method and system for industrializing a designed part. This invention includes selecting a parting surfaceto divide the designed part, which includes a functional specification, into a first side and a second side, and selecting a draft angle. A change is computed in the first side and the second side using the selected draft angle. During the computation, the functional specification is maintained and the first side and second side meet on the parting surface. A face and a pulling direction can also be selected on the designed part. The selected face can be parallel to the pulling direction for the first side. Faces adjacent to the selected face can also be used in the computation. Once computed, the industrialized designed part can be displayed. An optimal blend draft method or a driving/driven blend draft method can be selected to compute the designed part.

摘要： The invention notably relates to a method for designing a 3D modeled object. Provided is a modeling graph having nodes that represent geometrical objects and arcs that each represent a relationship, wherein procedural relationships are represented by unidirectional arcs, wherein the relationships linking the geometrical objects further include live relationships that are represented by bidirectional arcs, and wherein the provided modeling graph respects a criterion that all the arcs of each strong component of the modeling graph are bidirectional. Upon adding a relationship linking two of the geometrical objects that are included in the data defining the 3D modeled object before the addition, the method selects two geometrical objects to be linked by the relationship to be added, the selection being performed according to the criterion.
Such a method improves the design of a 3D modeled object.摘要翻译： 本发明特别涉及一种用于设计3D建模对象的方法。 提供了一种具有代表几何对象的节点和各自表示关系的弧的建模图，其中过程关系由单向弧表示，其中，连接几何对象的关系还包括由双向弧表示的活动关系，并且其中提供 建模图表遵循建模图的每个强分量的所有弧都是双向的标准。 在添加之前添加关联定义3D建模对象的数据中包含的几个几何对象的关系，该方法选择要通过要添加的关系链接的两个几何对象，根据该标准执行选择。 这种方法改进了3D建模对象的设计。

摘要： The invention relates to a method of design of ruled surfaces, comprising a step of accessing data defining guiding curves P ( u ) and Q ( v ) (S110) and a cost function f ( t , w ) (S120). Given P ( u ) and Q ( v ), the unknown coupling is a parameterized curve s ↦ ( t ( s ), w ( s )). The method further comprises defining (S200) an objective function of the type J = J ( f , t , w ), involving both f ( t , w ) and coordinates t , w of the coupling curve. Then, optimizing the objective function J makes it possible to obtain the target coupling curve (S400). Finally, a ruled surface S ( s , λ) = λ Q ( w ( s ))+(1 - λ) P ( t ( s )) is provided (S500), according to the guiding curves P ( t ( s )) and Q ( w ( s )), composed with the coordinates t , w of the coupling curve previously obtained.
In addition, the objective function is further constrained at the optimization step (S200 - S400) such that arguments t , w of the cost function f ( t , w ) are regulated by a regulation function µ.
The invention generalizes to any surface defined by guiding curves and further concerns a computerized system and a computer program product comprising means adapted for implementing the method of the invention.摘要翻译： 本发明涉及一种设计规格表面的方法，包括访问定义引导曲线P（u）和Q（v）（S110）的数据和成本函数f（t，w）的步骤（S120）。 给定P（u）和Q（v），未知耦合是参数化曲线s†|（t（s），w（s））。 该方法进一步包括定义（S200）类型为J = J（f，t，w）的目标函数，涉及f（t，w）和耦合曲线的坐标t，w。 然后，优化目标函数J可以获得目标耦合曲线（S400）。 最后，根据引导曲线P（t（s））提供了刻度表面S（s，...）=»Q（w（s））+（1 - »）P（t（s））（S500） ）和Q（w（s）），由以前获得的耦合曲线的坐标t，w组成。 另外，在优化步骤（S200-40000）下进一步约束目标函数，使得成本函数f（t，w）的参数t，w由调节函数μ调节。 本发明概括到由引导曲线限定的任何表面，并且还涉及包括适于实现本发明的方法的装置的计算机化系统和计算机程序产品。
