不幸的是，实体建模是工程师在获得学位后学到的东西。尽管实体建模的发展缓慢，但它最终将成为大多数CAD/CAM应用程序的核心。实体建模领域的领先供应商将是CAD/CAM领域的领导者，在CIM应用方面将比其他供应商更具优势。在NC领域，实体建模可以提供增强的几何数据库，以执行复杂的多轴雕刻曲面编程。对于实体，可以验证零件，然后进行加工，从而消除许多或所有原型阶段。

UNFORTUNATELY, SOLIDS MODELING IS SOMETHING THE ENGINEER LEARNS AFTER RECEIVING A DEGREE. DESPITE THE FACT THAT SOLIDS MODELING HAS BEEN SLOW TO CATCH ON, IT WILL EVENTUALLY BECOME THE CORE OF MOST CAD/CAM APPLICATIONS. LEADING VENDORS IN SOLIDS MODELING WILL BE THE LEADERS IN CAD/CAM AND WILL HAVE THE ADVANTAGE OVER OTHERS WHEN IT COMES TO CIM APPLICATIONS. IN THE NC AREA, SOLIDS MODELING CAN PROVIDE AN ENHANCED GEOMETRY DATABASE TO PERFORM COMPLEX MULTI-AXIS SCULPTURE SURFACE PROGRAMMING. WITH SOLIDS, THE PART CAN BE VERIFIED, AND THEN MACHINED, THUS ELIMINATING MANY OR ALL PROTOTYPE STAGES.
