AutoCADR12.0半捏横担实体数学模型的建立

Founding Mathematical Model of Half Mediating Horizontal Supporter Entity with AutoCADR12.0

介绍了用C语言对AutoCAD二次开发而进行实物造型设计的数模建立过程，包括对实物进行模型分析和数模实现。在数模建立中，关键点的坐标变换和三维实体造型的基本命令都必须符合ADS和AutoCAD中的规范，其数据获取和数模建立要比其他情况复杂。

This paper mainly introduces the process of modeling that carries out the design about the model of entity using the second development system of A utoCAD by means of language C. It includes the analysis of entity modeling and achievement of model. During the modeling, the coordinate transformation of key point and the basis commands of 3-D entity model conform to some specific standard of AOS language and A utoCAD software. The achievement of data and foundation of mathematical model is more complicated than others.
