The method of drawing a part with helix property by AutoLisp language in AutoCAD;

The flowing of polymer melt in the head was simulated by AutoLisp language,which was helpful to get a clear understanding of the flowing law of melt and to design the structure and strength of the head of hollow blow molding machine in imitation of actual situation.

The parametric drafting of AutoCAD softwares is fulfilled by the the adoption of Autolisp language.

Strengthening design capability of AutoCAD by using AutoLISP language;

This paper describes the use of AutoLISP language secondary development of the construction procedures red line testing data automatically into Total Station process.

Combines FORTRAN and AUTOLISP, this paper completes themulti-parameter.

Using Program Edited by the Language of Auto LISP Realizes the Parameterisation to Modify the Drawing o f Auto CAD;

Auto LISP, a sort of high level language, has the greatest graphical function in AutoCAD softwares.

Therefore,a new method is presented in this paper to realize parametric drawing by combining advanced programming language and Auto LISP,and a mixed language programming design system of FORTRAN and Auto LISP are developed.

Gauge CAD system based on AutoCAD is introduced in this paper, and in addition, the key techniques used in the development of this system,including the mixed programming by Object ARX and VLISP is discussed.

Through the second development of AutoCAD, an object oriented gear hob CAD system is developed by means of Object ARX in the developing environment of Visual C ++ 6 0.
