Abstract
A CAD system, method, and computer readable medium. A method includes loading a CAD object including a plurality of faces, and identifying a plurality of candidate faces from the plurality of faces. The candidate faces can include candidate blends. The method includes combining multiple ones of the candidate faces into a candidate blend chain, including at least one candidate blend. The method includes replacing the candidate blends with accurate blends to produce a corrected blend chain, and storing the corrected blend chain with the accurate blends as part of the CAD object.

A method for use in a CAD system, comprising:
- loading a CAD object in a CAD system, the CAD object including a plurality of faces;
- identifying, by the CAD system, a plurality of candidate faces from the plurality of faces, the candidate faces including candidate blends;
- combining, by the CAD system, multiple ones of the candidate faces into a candidate blend chain, including at least one candidate blend;
- replacing, by the CAD system, the candidate blends with accurate blends to produce a corrected blend chain;
- and
- storing the corrected blend chain with the accurate blends in the CAD system as part of the CAD object.
A CAD system comprising a processor and accessible memory, the CAD system configured to perform the steps of:
- loading a CAD object including a plurality of faces;
- identifying a plurality of candidate faces from the plurality of faces, the candidate faces including candidate blends;
- combining multiple ones of the candidate faces into a candidate blend chain, including at least one candidate blend;
- replacing the candidate blends with accurate blends to produce a corrected blend chain;
- and
- storing the corrected blend chain with the accurate blends as part of the CAD object.
A tangible computer-readable medium encoded with computer-executable instructions that, when executed, cause a data processing system to perform the steps of:
- loading a CAD object including a plurality of faces;
- identifying a plurality of candidate faces from the plurality of faces, the candidate faces including candidate blends;
- combining multiple ones of the candidate faces into a candidate blend chain, including at least one candidate blend;
- replacing the candidate blends with accurate blends to produce a corrected blend chain;
- and
- storing the corrected blend chain with the accurate blends as part of the CAD object.
