Understanding Application Loading in AutoCAD 2025

Loading applications in AutoCAD is a crucial step for enhancing your drawing capabilities. It allows users to implement custom functionalities through various file formats, such as AutoLISP. Below is a comprehensive guide explaining how to load applications in AutoCAD 2025 effectively.

Step-by-Step Guide to Loading Applications

Accessing the Load Application Command

  1. Open AutoCAD: Launch the AutoCAD application on your machine.
  2. Command Line Access: Navigate to the command line at the bottom of the interface. This is where you will input commands directly.
  3. Input Command: Type APPLOAD into the command line and press Enter. This will open the Load Application dialog box.

Selecting the Application

  1. Navigate to File Location: In the Load Application dialog, you can browse through your directories to locate the application file you wish to load. Common file types include .lsp for AutoLISP files.
  2. Choose File: Once you find the desired file, click on it to highlight it.
  3. Load the Application: Click the Load button in the dialog. This action will load the selected application into the current AutoCAD session.

Verifying Loaded Applications

  1. Check Loaded Application: After loading, look for feedback in the dialog box indicating successful loading. You may also see the application listed in the ‘Loaded Applications’ section.

Understanding Session Limitations

Loading an application through the APPLOAD command will only keep the application available for the current session. To ensure it’s loaded in future sessions, consider adding it to the Startup Suite, as detailed below.

Adding Applications to the Startup Suite

  1. Open APPLOAD: Return to the command line and enter APPLOAD again.
  2. Select Startup Suite: In the dialog that appears, look for the Startup Suite options.
  3. Add Applications: Click the Contents button, then the Add button. Browse to your application file, select it, and click Open.
  4. Close the Dialogue: After adding the application, click Close to finish. Your application will now load automatically whenever AutoCAD starts.

Frequently Asked Questions

What file types can be loaded into AutoCAD?
AutoCAD primarily supports .lsp files for AutoLISP programs, .scr files for scripts, and other custom extension files that enhance functionality.

Can I use downloaded applications and scripts in AutoCAD LT?
No, AutoCAD LT does not support AutoLISP or the APPLOAD command, making it impossible to load custom applications in that version.

How do I unload an application in AutoCAD?
To unload an application, open the APPLOAD dialog, and in the ‘Loaded Applications’ section, select the application you wish to unload. Click the Unload button to remove it from the current session.
