The core steps of loading LISP programs to AutoCAD include: 1. Prepare the correct .lsp file and recommend storing it in a fixed folder; 2. Load it using the APPLOAD command, and then load it after browsing; 3. Optional settings for automatic loading, add the file to the startup suite to achieve automatic operation every time, but attention should be paid to affecting the startup speed. The whole process is simple but you need to pay attention to the accuracy of the path and command.
Loading LISP programs to AutoCAD is an operation that many CAD users use in daily life, especially when using customized commands or plug-ins. In fact, this process is not complicated, the key is to master several core steps.

1. Prepare the LISP file
A LISP program is usually a text file ending in .lsp
. First, you need to confirm that you have obtained the correct LISP file and know where it is stored on your computer.

- Frequently Asked Questions: Some users may save files in places that are not easy to find after downloading, and it is recommended to place them in a fixed "AutoCAD Plug-in" folder.
- Tips: If you are not sure whether a LISP is compatible with the current version of AutoCAD, you can check it online or find the author's instructions.
2. Load LISP using the APPLOAD command
This is the most commonly used method and is suitable for most cases:
- Enter
APPLOAD
(case insensitive) on the AutoCAD command line and press Enter. - Click "Browse" in the pop-up window to find your
.lsp
file. - After selecting the file, click "Load" and then click "Close".
After the loading is completed, the commands in the LISP program can be used directly. For example, some programs can run functions by entering custom commands like MYCMD
after loading.

Note: Do you need to reload every time you open a new drawing? No, if you add it to the "Startup Kit", it will load automatically.
3. Set up automatic loading (optional)
If you use a LISP program frequently and don't want to load manually every time, you can set it to automatically load:
- In the
APPLOAD
window, find the "Startup Suite" area. - Click the "Add" button to select the
.lsp
file you want to load automatically. - After joining, it will automatically run the program every time you start AutoCAD.
This saves the trouble of repeated operations. But be aware that too many autoloaded plugins may slow down AutoCAD startup.
Basically that's it. The whole process is not difficult, but it is easy for novices to get stuck in the file path or command misspelling when they first operate. Just try it once and you can get it done in a few minutes after getting familiar with it.
