Abstract
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.
