Abstract

Product Data Management (PDM) systems and methods. A method includes receiving a target body and a tool body, and evaluating a body type of the target body and a body type of the tool body. The method includes evaluating interactions between the target body and the tool body, and applying comparison criteria to determine spatial relation and relative convexity of an intersection between the target body and the tool body. The method includes identifying tool face regions of the tool body based on the evaluations and the determined spatial relation and relative convexity of the intersection. The method includes adding the tool face regions to the target body to produce a modified target body.

First claim

determining a spatial relation and relative convexity of an intersection between the target body and the tool body;
identifying tool face regions of the tool body based on the evaluations and the determined spatial relation and relative convexity of the intersection;
splitting the tool face regions from the tool body and maintaining the tool face regions as a separate body from the tool body; and
adding the tool face regions to the target body to produce a modified target body.

2. The method of claim 1 , wherein evaluating interactions between the target body and the tool body includes evaluating a number of, geometric characteristics of, and topological characteristics of the intersection between the target body and the tool body.

3. The method of claim 1 , wherein evaluating interactions between the target body and the tool body includes evaluating a number of, geometric characteristics of, and topological characteristics of intersecting face sets between the target body and the tool body.

4. The method of claim 3 , wherein the PDM data processing system also identifies at least one face loop between the target body and tool body that corresponds to an intersection between respective faces of the target body and the tool body.

5. The method of claim 1 , wherein evaluating interactions between the target body and the tool body includes evaluating a number of, geometric characteristics of, and topological characteristics of face regions of the target body and the tool body.

6. The method of claim 1 , wherein the PDM data processing system also determines distinguishing characteristics of the intersection between the target body and the tool body.
