A method and corresponding system is provided for determining an optimum manufacturing process routing. The method comprises electronically constructing a plurality of manufacturing process routings for a component to be manufactured. The electronically constructing for each manufacturing process routing of the plurality of manufacturing process routings comprises defining a recursive process routing tree for each manufacturing process routing, the recursive process routing tree comprising a plurality of nodes, each node of the plurality of nodes corresponding to a manufacturing process and comprising a branch node when the manufacturing process for a given node may be decomposed into a plurality of sub-processes for the given node. The method further comprises electronically determining an optimum process routing by evaluating each recursive process routing tree with reference to a cost for manufacturing the component to be optimized and determining the optimum process routing that minimizes the cost for manufacturing the component.

Template framework for automated process routing

A facility enables an external application program (EAP) to exchange data with a modeling program, such as a computer-aided design (CAD) program. The data may be parametric data used in parametric models of geometric objects in the CAD program. In one embodiment, the EAP registers with the CAD program to indicate that the EAP provides output data to the CAD program for use within a model. When the CAD program needs to reevaluate a model due to changes, the CAD program calls a callback that results from the registration of the EAP with the CAD program. The callback sends new input data to the EAP, causes the EAP to recalculate the output data and pass the new output data to the CAD program. The CAD program then integrates the new output data into the model so as to fully update the model.

Parametric exchange of data between a modeling system and an external application program

An analysis may be represented as a feature in a feature-based model of a geometric object. The analysis is integrated directly into the model and may be recalculated in response to changes made to the model. Additional features may be created that reference the analysis feature. Likewise, the model may include features that reference the analysis without directly incorporating the analysis into the model as a feature. The analysis may be a system-defined analysis, a user defined analysis or an external analysis.

Integration of an analysis into the features of a model of an object

A computer implemented method for dynamically updating a geometric model uses a data structure in which selected constituent elements of the model are associated to form a logical element with dynamically linked pointers to the selected constituent elements. One or more procedures reference the logical element as an input parameter. This indirect referencing of the constituent elements enables the procedure to accommodate fundamental changes to the selected constituent elements without requiring a designer to change the input parameter list of the procedure.

Method and system for dynamically updating geometric models

A modeling program allows a user to create macros for implementing user-defined functionaliy. The macros may, for example, perform an engineering analysis on a model. The macro uses features as macro language instructions. The macro may be applied to an arbitrary portion of any model because the representation of the features in the macro is generic.
