Steps to Load a LISP File in AutoCAD 2025
Loading a LISP file in AutoCAD can enhance productivity by automating repetitive tasks and customizing functionalities. The following steps will guide you through the process.
Step 1: Open the APPLOAD Command
To begin, launch AutoCAD and type APPLOAD into the command line. Press Enter after typing the command. This action opens the "Load Applications" dialog, where you can manage your LISP files.
Step 2: Access the Startup Suite
Within the "Load Applications" dialog, locate the "Startup Suite" section. Here, you will find options to manage files that load automatically when AutoCAD starts.
Step 3: Add New LISP Files
Click on the "Contents" button within the Startup Suite. A new window will appear displaying the current files in the suite. To include your LISP file, select the "Add" button.
Step 4: Select Your LISP File
A file browsing window will open. Navigate to the directory where your LISP file is stored. Select the desired .lsp file and click the "Open" button. This action adds your LISP routine to the Startup Suite, allowing it to be loaded automatically upon starting AutoCAD.
Step 5: Finalize Your Changes
After adding the LISP files, click the "Close" button in the Startup Suite window. This returns you to the previous dialog. To confirm that your LISP files have been added successfully, review the list displayed in the Startup Suite section.
Step 6: Load the LISP File Manually (Optional)
If you want to load a LISP file without adding it to the Startup Suite, you can do so directly from the main “Load Applications” dialog. Simply locate the LISP file in the browser window, select it, and click "Load." After loading, click "Close" to exit the dialog.
