CAD系统图中的模块作为面向问题扩展开发的基础
The modulus in the CAD system drawings as a base of developing of the problem-oriented extensions
摘要：
对CAD系统图形中的“模数”概念进行了刻画，为开发面向问题的扩展模块奠定了基础。模数由绘图的可见几何元素和建模对象的不可见参数表示组成。阐述了模块化在复杂CAD系统开发中的技术优势。
英文摘要：
The concept of the "modulus" in the CAD system drawings is characterized, being a base of developing of the problem-oriented extensions. The modulus consists of visible geometric elements of the drawing and invisible parametric representation of the modelling object. The technological advantages of moduluss in a complex CAD system developing are described.
