Non-variational changes in a variational system
View Patent ↗Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a three-dimensional CAD model in the data processing system, the CAD model including a plurality of features. The method includes receiving a selection of a non-variational function to be applied to the CAD model, including a selection of at least one feature to which the function is to be applied. The method includes creating a copy of the selected feature as a second body to produce a modified feature and adding the modified feature to a solver configuration of the CAD model. The method includes solving the CAD model according to the solver configuration to produce a modified CAD model, and storing the modified CAD model.
