How Do I Save a Variable in AutoCAD?

by

Saving variables in AutoCAD is essential for keeping track of important data and settings. Whether you want to save a specific value or a group of variables, AutoCAD provides several methods to accomplish this task.

Using the SETVAR Command

The SETVAR command in AutoCAD allows you to set the value of a system variable and save it for future use. Here’s how you can do it:

  • Type SETVAR in the command line
  • Press Enter
  • Enter the name of the variable you want to set
  • Press Enter
  • Enter the desired value for the variable
  • Press Enter

Saving Variables with LISP Functions

If you frequently use specific sets of variables, using LISP functions can save you time and effort. Here’s how:

  • Create a new LISP file or open an existing one in a text editor
  • Add the following code to define your variable values:
    • (setq myVariable1 value1)
(setq myVariable2 value2)
(setq myVariable3 value3)
..
(setq myVariableN valueN)
  • Save the LISP file with a .lsp extension
  • In AutoCAD, type APPLOAD in the command line and press Enter
  • Browse and select your .lsp file, then click Load/Unload.
  • Enable the “Load Automatically” option and click Close

Using AutoLISP Customization Files

If you want to save your variables permanently and have them available every time you start AutoCAD, you can use AutoLISP customization files. Follow these steps:

  • Create a new text file in a text editor
  • Add the following code to define your variable values:
  • Save the file with a .lsp extension, such as acad.lsp or acaddoc.lsp
  • Place the .lsp file in the AutoCAD support path folder
  • The support path folder is usually located in:
    • C:\Users\YourUsername\AppData\Roaming\Autodesk\AutoCAD 20XX\RXX.X\enu\Support
  • Restart AutoCAD for the changes to take effect

Conclusion:

Saving variables in AutoCAD is crucial for preserving important data and settings. Whether you use the SETVAR command, LISP functions, or AutoLISP customization files, understanding how to save variables will help you work more efficiently and effectively in AutoCAD.
