How To Use Netload In AutoCAD?

Understanding NETLOAD in AutoCAD

NETLOAD is a command utilized in AutoCAD to load .DLL (Dynamic Link Library) files, allowing users to run custom AutoCAD commands and applications. Here’s a detailed guide on how to effectively use NETLOAD in AutoCAD.

Step-by-Step Process to Use NETLOAD in AutoCAD

1. Prepare Your .DLL File:
   Ensure that you have the .DLL file ready to load. This file typically contains custom features or commands you want to utilize in AutoCAD. Make sure that this file is compatible with your version of AutoCAD.

2. Create an LSP File:
   To ensure seamless loading, create an accompanying LISP (.LSP) file. This file should include the necessary code to call your .DLL file. The LISP code should include the following syntax:
   lisp
   (command “NETLOAD” “path_to_your_dll_file”)

   Replace "path_to_your_dll_file" with the actual path of your .DLL file.

3. Store the LSP File:
   Save the LSP file in a designated folder on your computer. It’s important to note the location, as you will need it for the next steps.

4. Configure Trusted Locations:
   Launch AutoCAD and navigate to the Options dialog. Under the Files tab, locate the Trusted Locations section. Add the folder containing your LSP file. This step is crucial, as AutoCAD restricts loading files from untrusted locations for security reasons.

5. Open AutoCAD:
   If you had AutoCAD open while preparing files, close and restart the application to ensure all settings take effect.

6. Load the .DLL File:
   In the command line, type NETLOAD and press Enter. A file dialog will appear; navigate to your .DLL file and select it. The .DLL will load, and you should receive a confirmation message indicating successful loading.

7. Run Your Commands:
   After successfully loading the .DLL, you can now use any custom commands or features defined within that .DLL file. If integrated properly, these commands should execute as intended.

Frequently Asked Questions

1. What should I do if my .DLL file fails to load using NETLOAD?
If the .DLL file fails to load, verify that the file path is correct and that the file is compatible with AutoCAD 2025. Additionally, ensure that the required dependencies for the .DLL are installed.

2. Can I load multiple .DLL files simultaneously with NETLOAD?
While the NETLOAD command is designed to load one .DLL at a time, you can create a more extensive LISP file that sequentially loads multiple .DLL files by using multiple instances of the NETLOAD command within it.

3. Are there any security concerns when loading .DLL files into AutoCAD?
Yes, loading .DLL files from unverified sources poses security risks, including the potential for malware. Always ensure that the .DLL files are obtained from trusted sources and consider running a malware scan on the files before use.
