How Do You Automate Drawings in AutoCAD?

by

In this tutorial, we will learn how to automate drawings in AutoCAD. Automating the drawing process can save a significant amount of time and effort, especially when working on complex projects. AutoCAD provides several tools and features that allow you to automate various aspects of the drawing process.

1. Templates

Templates are pre-designed drawing files that contain all the necessary settings and standards for a specific type of drawing. By using templates, you can automate the creation of new drawings with predefined layers, dimension styles, text styles, and other settings.

Creating a Template

To create a template in AutoCAD:

  • Step 1: Open a new drawing with the desired settings.
  • Step 2: Customize the drawing settings, including layers, dimension styles, text styles, etc.
  • Step 3: Save the file as a template by selecting “Save As” and choosing the file type as “Drawing Template (*.dwt)”.

Using a Template

To use a template in AutoCAD:

  • Step 1: Open a new drawing using the template by selecting “New” from the File menu and choosing the desired template from the list.
  • Step 2: Start working on your drawing using the predefined settings from the template.

2. Scripts

In AutoCAD, scripts are text files that contain a series of commands that can be executed sequentially. You can create scripts to automate repetitive tasks or perform complex operations with just a few clicks.

Creating a Script

To create a script in AutoCAD:

  • Step 1: Open a text editor such as Notepad.
  • Step 2: Write the desired commands, each on a new line.
  • Step 3: Save the file with a “.scr” extension.

Running a Script

To run a script in AutoCAD:

  • Step 1: Open the drawing where you want to run the script.
  • Step 2: Type “SCRIPT” in the command line and press Enter.
  • Step 3: Browse and select the script file from your computer.

3. AutoLISP

AutoLISP is a dialect of the LISP programming language that is built into AutoCAD. It allows you to create custom programs and functions to automate various tasks in AutoCAD.

Creating an AutoLISP Program

To create an AutoLISP program in AutoCAD:

  • Step 1: Open a text editor such as Notepad or use the Visual LISP Editor within AutoCAD.
  • Step 2: Write the AutoLISP code, starting with “(defun C:yourCommandName ()”, followed by your code, and closing with “)” (e.g., (defun C:MyCommand () (command “circle”))).
  • Note:You can define your own command name and customize the code based on your requirements.lsp” extension.

Loading and Running an AutoLISP Program

To load and run an AutoLISP program in AutoCAD:

  • Step 1: Type “APPLOAD” in the command line and press Enter.
  • Step 2: Browse and select the AutoLISP program file from your computer.
  • Step 3: Type the defined command name in the command line to execute the program (e., “MyCommand”).

Conclusion

In this tutorial, we have explored various methods to automate drawings in AutoCAD. By utilizing templates, scripts, and AutoLISP programming, you can save time and effort by automating repetitive tasks and customizing your drawing process. Experiment with these techniques to streamline your workflow and increase productivity in AutoCAD.
