how to load a lisp in autocad

AutoCAD is a popular Computer-Aided Design (CAD) application used in various industries, including architecture, engineering, and construction. Lisp, a programming language commonly used for CAD applications, can help users automate their workflow and improve productivity. In this article, we’ll demonstrate step-by-step how to load a Lisp routine in AutoCAD.

Step 1: Locate the Lisp File

The first step in loading a Lisp routine is to locate the Lisp file. The Lisp file contains the code that defines the routine’s functionality. Usually, users can obtain Lisp files through third-party websites or by creating their own Lisp routines. Typically, Lisp files have the ‘.lsp’ extension. Once you have located the Lisp file, make sure to save it in a directory where AutoCAD can access it easily.

Step 2: Open AutoCAD

Next, open AutoCAD. To load a Lisp routine, you must navigate to the ‘Manage’ tab, which contains all relevant tools for managing customizations in AutoCAD.

Step 3: Load the Lisp File

Click on the ‘Customization’ tab located in the ‘Manage’ tab. From the dropdown menu, select ‘Edit Program Parameters’. This action opens the ‘ACADDOC.LSP’ file, which is a customizable Lisp file that the AutoCAD application looks for at startup. Add the following line of code to the end of the ‘ACADDOC.LSP’ file: (load \"C:/LISP/routine.lsp\") Here, we assume that the ‘routine.lsp’ file is saved in the directory ‘C:/LISP/’. Make sure to replace this with your actual directory path and file name. Save the ‘ACADDOC.LSP’ file by clicking ‘Save Changes’ and then closing it.

Step 4: Test the Lisp Routine

To test the newly loaded Lisp routine, type the command that invokes the routine in the command line. If everything has been done correctly, AutoCAD should execute the Lisp routine and display the desired output. If the routine does not run correctly, go back to the Lisp file and check for any errors.

Conclusion

In conclusion, loading a Lisp routine in AutoCAD involves locating the Lisp file, opening AutoCAD, editing the ‘ACADDOC.LSP’ file, and testing the routine. Users can improve their productivity by creating or downloading custom Lisp routines that can automate tedious tasks in AutoCAD. With a little practice and knowledge of Lisp programming, users can create powerful routines that suit their specific needs.
