AutoCAD Training Overview
Learning AutoLISP is radically different from learning AutoCAD. AutoLISP is a programming language with its own commands, its own structure, and its own syntax. However, AutoLISP knowledge, AutoCAD operators can amplify their powers with AutoCAD.
AutoCAD Training Topics
- Getting started with AutoLISP
- Creating usable AutoLISP routines
- Creating lists and error trapping
- Repeating actions and branching
- Accessing the drawing database
- Data formatting and text files
- Debugging with Visual LISP
