Abstract

A set of self-defined model data structure using discrete boundary representation is designed in this paper, based which the modeling data is transformed from CAD to CAE pre-process. And so the geometric modeling function is realized. By the unified data interface, model data is read and transformed from a variety of mainstream and standard CAD model file such as IGES, STEP and so on. By studying and parsing the STL file and Tribon XML format file, the STL model file and ship CAD model data conversion is realized.
