油气工艺CAD的比例处理问题

Proportion treatment for oil-gas fields technology CAD

从解决油气工艺设计图中的比例问题出发,结合实践研究对用AutoLISP实现CAD比例处理的方法,并提出具体的对策。

From the problem of the most difficult proportion in design drawing of oil-gas fields technology,and combined with the practice,the text studies the methods of accomplishing CAD proportion treatment with AutoLISP and presents some concrete countermeasures.
