Abstract
A method for determining a similarity of a first solid model to a second solid model is disclosed. The method includes the steps of: selecting a set of features for representing the first solid model; extracting features corresponding to the selected set of features from the first solid model; constructing an undirected model dependency graph of the first solid model based on the selected set of features; extracting features corresponding to the selected set of features from the second solid model; constructing an undirected model dependency graph of the second solid model based on the selected set of features; comparing the undirected model dependency graph of the first solid model with the undirected model dependency graph of the second solid model; and outputting a numerical measure indicative of the similarity of the first solid model to the second solid model.
