公差和表面光洁度数据对于自动规划机械部件的制造、检测和机器人装配至关重要。一种用于在基于构造性实体几何（CSG）的实体建模器中表示表面特征并将公差和其它属性与这些特征相关联的方案。它最终表明，普遍持有的信念CSG的无法处理的表面特征和公差是没有根据的。该方案已在PADL-2建模系统中实现，并正在用于支持数控机床编程高级语言的研究。
Tolerancing and surface finish data are essential for automatically planning the manufacture, inspection, and robotic assembly of mechanical components. A scheme for representing surface features in a solid modeler based on constructive solid geometry (CSG) and for associating tolerances and other attributes with such features. It shows conclusively that commonly-held beliefs on CSG's inability to deal with surface features and tolerances are unfounded. The scheme has been implemented in the PADL-2 modeling system and is being used to support research on high-level languages for programming numerically controlled (NC) machine tools.
