产品数据表达与交换标准STEP为CIM系统的信息集成提供了重要的技术支持。
The standard for product data representation and exchange STEP can provide sufficient technical support for the information integration of CIM system.
使用现有的产品数据表达与交换标准STEP只能描述CAD模型几何、拓扑和部分运动学信息,对多刚体动力学特征的描述一直是特征模型中的一个空白。
But there are only basic info of geometry, topology and partial kinematics in the CAD model in STEP. The description on feature of multi-rigid-body dynamics is hardly blank.
