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： The invention relates to a method of design of ruled surfaces. The method comprises the step of accessing data defining guiding curves P(u) and Q(v) and a cost function f(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(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. Finally, a ruled surface S(s, λ)=Q(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. The objective function is further constrained at the optimization step 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： 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.
