摘要： This invention presents a method and system for industrializing a designed part. This invention includes selecting a parting surface to 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： A computer-implemented method of design of ruled surfaces may comprise the step of accessing data defining guiding curves P(u) and Q(v) and a cost function ƒ(t,w). Given P(u) and Q(v), the unknown coupling is a parameterized curve s(t(s),w(s)). The method further comprises defining an objective function of the type J=J(ƒ,t,w), involving both ƒ(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. Finally, a ruled surface S(s,λ)=λQ(w(s))+(1−λ)P(t(s))is provided, 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 such that arguments t,w of the cost function ƒ(t,w) are regulated by a regulation function μ.

摘要： A declarative system for designing parts or assemblies of parts is based on a history-based design system (40), which has a storage format with primitives and operations; a modeled object is defined in the history based design system by an ordered sequence of operations and primitives. The declarative system has several functional features, which may be selected (48) and instantiated by a end user by providing a set of specifications (46) to a end-user interface (44). An instantiated functional feature provides contributions (50), each contribution being an ordered sequence of operations and primitives of the history-based design system. Contributions (50) are received by a seed structure (52). The seed structure is defined in a context-free grammar. The seed structure orders operations and primitives of received contributions provides an ordered sequence (54) of operations and primitives to the history based system. An editor (56) makes it possible to edit the seed structure in the grammar.

摘要： The invention provides a computer-implemented method and system intended for designing an assembly of a plurality of objects. The assembly is modeled by a directed acyclic modeling graph having nodes and arcs. Each node represents an object of the assembly. Each arc represents the use of an end node by an origin node. At least one arc is uniquely identified by an identifier. The assembly is further modeled by at least one relation having at least one tuple containing a first chain of at least one identifier. The method comprises determining at least one mapping between the first chain and a second chain of at least one identifier as well as substituting at least one occurrence of the first chain in the tuple of the relation with the second chain. The invention provides a means to repair broken tuples automatically and thus to facilitate design.
