Brep model simplification for feature suppressing using local error evaluation

The CAD model simplification technology has been paid more and more attentions for the requirement of seamless integration of CAD/CAE/CAM. This paper presents a new approach for feature suppressing of Brep models using local error evaluation. The improvement is that several features can synchronously be suppressed, and time overhead will be reduced at initial step without recognizing among most of them.
