Intermediate AutoLISP

This course is aimed at the person with some LISP or AutoLISP experience. AutoLISP is one of the easiest languages to learn and is very powerful. All of my plugins for AutoCAD are written in AutoLISP and Visual LISP.

Although this course is based on programming AutoLISP for AutoCAD, other CAD applications, such as IntelliCAD-based CAD applications BricsCAD and ZWCAD, use AutoLISP programming. Therefore, you can write these applications for more than one CAD program. You do not need any prior experience to program in this language.

For those with more experience, you can move on to the “Advanced AutoLISP Programming” lessons. To learn how to create plugins for AutoCAD with a dialog interface, reference the course “How to Write Custom Dialog Box Programs” using AutoLISP and the DCL dialog control language.

If you have a copy of AutoCAD, you can use the AutoLISP User Interface, VLIDE, to help make coding, testing, debugging, and compiling output easier and more productive. This book does not cover the usage of this interface, which you can find in the AutoLISP help section. To start the VLIDE, type this at the AutoCAD Command prompt: Command: VLISP

If you are using one of the IntelliCAD-based programs, you can use Notepad, Textpad, or Notepad++

What You’ll Learn?

This course is and expansion of the Basic Programming Concepts which include more advanced versions of the following:

Variables: Declaring and assigning values to variables.

Data Types: Understanding different data types (numbers, strings, lists).

Operators: Using arithmetic, comparison, and logical operators.

Control Flow: Learning about conditional statements (if-else) and loops (while, repeat).

Functions: Defining, calling, and passing arguments to functions.

AutoLISP-Specific Concepts

AutoCAD Command Line Interface: Interacting with AutoCAD using AutoLISP.

Entity Selection: Selecting objects in the drawing using various selection methods.

Entity Data Extraction: Extracting information from selected entities (coordinates, properties, etc.).

Entity Creation and Modification: Creating and modifying various AutoCAD entities (lines, circles, text, etc.).

Input and Output: Prompting users for input and displaying output to the command line.

Error Handling: Implementing error checking and handling mechanisms.

Practical Applications

Automating Repetitive Tasks: Creating scripts to automate common tasks like block insertion, dimensioning, and layer management.

Customizing AutoCAD's Behavior: Developing custom commands and tools to extend AutoCAD's functionality.

Data Extraction and Analysis: Extracting data from drawings and performing calculations or analysis.

Creating Custom Dialog Boxes: Designing user-friendly interfaces for your LISP programs.

Additional Tips for Learning AutoLISP:

Practice Regularly: The more you practice, the better you'll become.

Break Down Complex Problems: Divide complex tasks into smaller, more manageable subtasks.

Debug Your Code: Use the debug function to step through your code and identify errors.

Learn from Others: Study existing LISP code and seek help from online forums and communities.

Experiment and Have Fun: Don't be afraid to try new things and make mistakes.

By mastering these core concepts, you'll be well-equipped to write efficient and effective AutoLISP programs to automate your CAD workflows and increase your productivity.
