REPL, or Read-Evaluate-Print-Loop, is a standard feature for dynamic languages such as Ruby, Python, and Lisp. 即“读取-求值-打印-循环(Read-Evaluate-Print-Loop)”,是诸如Ruby、Python和Lisp这样的动态语言的一个标准特性。
The paper aims at the development of parametric standard parts of chemical engineering equipment by means of Visual LISP in order to solve some problems that occur when AutoCAD is used to help design chemical engineering equipment. 针对AutoCAD辅助化工设备设计时易出现的问题,用VISUALLISP开发了参数化的化工设备标准件库,并用实例展示了其可操作性。
Lastly, the paper shows a LISP function to turn any logical expression into a standard form. 本文最后给出了比较两条产生式规则前件所使用的化任意逻辑表达式为标准型的LISP函数。
Research on 2D and 3D parametric design for mechanical standard parts based on visual LISP 基于VISUALLISP的二三维标准件图形参数化设计研究
Developing the AutoCAD's internal and external database with Visual LISP language, using external database to save design parameters of chemical engineering standard parts, the paper realizes the creating from database to graphic database. 提出采用VISUALLISP语言直接对AutoCAD内部和外部数据库进行操作,用外部数据库存储标准件的设计参数,实现从数据库生成图形库。的设计,平均性能提高26%。
The Automatically Setting Program of CAD engineering drawing environment parameters has been developed by Visual LISP, it can help users set the AutoCAD drawing environment parameters by Rule of international standard in order to realize draw in full scale. 用VISUALLISP语言开发了CAD工程图的绘图环境参数自动设置程序,可以帮助用户快速地完成绘制CAD工程图时对AutoCAD的绘图环境参数进行国标化设置,以实现1:1比例绘图。
