LISP is a programming language, and the best way to learn any programming language is by practicing its use.
You will immediately see the string 'Hello, world' displayed at the prompt. Type 'hello' (without quotes) at the AutoCAD command prompt. From the 'Tools' menu, select 'AutoLISP' and 'Load.' Select the hello.lsp file, and click 'Load.' The file is now ready to run.
If it displays an error code, fix the listed errors in your code and save and load the code again. And that’s how you create and load a startup LISP routine. Navigate to the location of where your LISP file is, and it will appear in the list. Load the program, and from the 'Tools' menu, select 'Load Text in Editor.' The VLISP window should display a confirmation message. Next, find the LISP Files category in the Customization in All Files section of the CUI dialog box, right-click on it, and choose Load Lisp from the context menu. Save the routine by choosing 'Save As.' from the 'File' menu, then save the file as 'hello.lsp'. The rest of the program displays the string at the command prompt.
The first line defines the 'Hello, world' function. (defun c:hello () (prompt 'Hello, world!') (princ) ) To create a 'Hello, world' application to work at the AutoCAD command prompt, enter the following code: Launch the VLISP text editor by selecting 'File', then 'New.' The text editor enables you to write and save complete LISP programs, or routines.īegin your VLISP routine. From the AutoCAD window, in the 'Tools' menu, select 'AutoLISP' and 'Visual LISP Editor.' In the VLISP window, you can type LISP commands in the console window. I’d be very grateful if anyone has any idea what’s going on here. You can use the VLISP interface to write and run LISP routines in AutoCAD.įor some reason AutoCAD crashes I try to copy text to clipboard and pasting to another tab in the same drawing. LISP, the name of which is derived from LISt Processing, is a computer programming language that is interfaced with AutoCAD using VLISP, or Visual LISP.
If you use AutoCAD every day, and find there are routines that you would like to automate, AutoCAD offers a way to do this: LISP routines. It is used to create blueprints, schematics and other engineering drawings and 3D models.
AutoCAD, from AutoDesk Software, is one of the most common software programs in use today in the engineering industry.
