Geometry Information Extraction from The STEP Neutral File
It is one of the key technologies for the integration of CAD/CAM/CAPP to extract the geometric model information． Based on a systematic analysis and comprehension on the expression of STEP geometry model the map between EXPRESS and C++was studied．The module of map has been developed as a dynamic link library．which facilitated the expansion of system．In order to ensure the coherence and availability of collected data,a module for data acquisition has also been designed．The reading and analvsis for STEP neutral file has been realized so that the geometry information in the STEP-based three-dimensional model could be extracted. Application illustration,which is used for supporting the slicing process in rapid prototyping，has been also presented． The method put forward in the paper is conducive to the integration of different CAX systems．
