AutoLISP & VisualLISP

 

AutoLISP lets users and AutoCAD developers write macro programs and functions well suited for graphics applications. AutoLISP applications or routines can interact with AutoCAD in many ways. These routines can prompt the user for input, access built-in AutoCAD commands directly and modify or create objects in the drawing database. By creating AutoLISP routines you can use AutoCAD as a design package.

 

Advantages of AutoLISP:

- Is easy to learn

- Is a built-in interpreter

- Powerful enough to handle graphical data.

- Is a simple structured programming language.
