1. A method for identifying a geometric feature association for a three-dimensional (3D) component model and a 3D manufacturing model, the method comprising:
superimposing the 3D manufacturing model on the 3D component model in a computer-aided drafting (CAD) environment;
identifying correspondence between a first geometric feature of the 3D component model and a second geometric feature of the superimposed 3D manufacturing model, wherein identifying correspondence between the first geometric feature of the 3D component model and the second geometric feature of the superimposed 3D manufacturing model includes generating a search box positioned on the second geometric feature and identifying that the first geometric feature is located within the search box;
measuring at least one distance between the first geometric feature and the second geometric feature based on the identified correspondence between the first geometric feature of the 3D component model and the second geometric feature of the superimposed 3D manufacturing model; and
identifying an association between the first geometric feature and the second geometric feature based on the at least one measured distance, wherein the association includes an association type between the first geometric feature and the second geometric feature based on the at least one measured distance, the association type including one or more of: a match, a deviation from nominal, a machining allowance or no match;
wherein the 3D component model is representative of a component in a manufactured condition, and the 3D manufacturing model is representative of the component in an intermediate state of manufacture.
