How to Load a Function in AutoCAD

Loading LISP functions into AutoCAD enhances its capabilities, offering custom automation tailored to your specific design needs. The process involves a series of straightforward steps that ensure your LISP routines are integrated seamlessly into AutoCAD’s environment.

Step-by-Step Guide to Load LISP Files

To load a LISP file, follow the below procedure:

  1. Initiate the APPLOAD Command: Begin by typing APPLOAD in the command line. This command opens the Application Loader dialog.
  2. Access the Startup Suite: Within the Application Loader dialog, look for the Startup Suite section and click on the Contents button. This will display the current list of loaded applications.
  3. Add Your LISP File: Click on the Add button. A file browser will appear, allowing you to navigate to the location of your LISP file. Select the desired LISP file and click Open.
  4. Confirm Your Selection: After adding your LISP file(s), click Close in the Application Loader dialog to save your selections and exit.

Loading LISP Functions Using the CUI Command

Another method to load LISP files is through the Customize User Interface (CUI) command:

  1. Invoke the CUI Command: Type CUI into the command line. This opens the Customize User Interface dialog box.
  2. Locate LISP Files Section: In the CUI dialog, traverse to the LISP Files category found in the Customization section on the left panel.
  3. Load Your LISP File: Right-click on the LISP Files category and select Load Lisp from the context menu. Then, navigate to your LISP file’s location and select it.
  4. Finalize the Loading: After your LISP file appears in the list, you can use it directly in your AutoCAD projects.

Working with DLL Files in AutoCAD

For users needing to integrate DLL files, follow these steps:

  1. Create a LSP File: Start by creating a LSP file that will call the desired DLL file.
  2. Place the LSP File: Save the LSP file in a directory on your computer.
  3. Add Trusted Location: In AutoCAD, go to the Options menu. Under the Files tab, add the folder containing your LSP file to the Trusted Locations section.
  4. Launch and Load: Open AutoCAD and use the NETLOAD command followed by the DLL file name. Once loaded, execute the APPLOAD command to finalize.

Do AutoCAD LT Users Have Access to LISP Functions?

AutoCAD LT users are unable to utilize AutoLISP since the APPLOAD command is not available in this version of AutoCAD. Consequently, those seeking advanced customizations must consider other options or use the full version of AutoCAD.

Understanding Key Components of AutoCAD

Familiarizing yourself with the various components of AutoCAD can help streamline your workflow:

Frequently Asked Questions

1. Can I load multiple LISP files in one go?
Yes, you can select multiple LISP files in the Application Loader dialog by holding down the Ctrl key while selecting.

2. What should I do if my LISP function does not seem to work?
Verify the path of your LISP file, ensure it is compatible with your current version of AutoCAD, and check for any syntax errors in the code.

3. Is programming knowledge required to create LISP routines?
While basic knowledge of LISP programming is beneficial, many resources are available online to help you learn and develop simple routines.
