How to use lisp with autocad?

thanks for the invitation and all experts in Autocad already answer this question in detail.

An AutoLISP file must be loaded into the AutoCAD program before it can be ran.

1. Open an AutoLISP (LSP) file and make sure the text editor is active.
2. In Visual LISP, do one of the following:
   • From the menu bar, click Tools Load.
   • From the Run toolbar, click Load Active Edit Window.

   A message is displayed in the Console window if the program was loaded successfully.

3. Start the AutoLISP function by doing one of the following:
   • At the Visual LISP Console window prompt, enter the name of a command or function name in parentheses, and press Enter.
   • At the AutoCAD Command prompt, enter the name of a command or function name in parentheses, and press Enter.

   If you switch back to Visual LISP before the command or function ends, the mouse pointer will appear as the Visual LISP icon. Switch back to AutoCAD and complete the command or function.

4. Respond to any prompts or dialog boxes that are displayed.

This example requires the installation of the Visual LISP Sample files.

1. In Visual LISP, click File Open File.
2. In the Open File dialog box, browse to the Sample\\VisualLISP folder, which is located in your AutoCAD installation directory.
3. Double-click the drawline.lsp file.
4. Make sure the text editor window containing the drawline.lsp program is active. If you are not sure whether the window is active, click anywhere in the window to activate it.
5. Click the Load Active Edit Window button from the Run toolbar, or click Tools Load Text in Editor.

   Visual LISP responds by displaying a message in the Console window indicating it has loaded the program.

6. Run thedrawlinefunction from the Console prompt by entering the function name in parentheses, then pressing Enter: (drawline)

   Thedrawlinefunction will prompt you to specify two points, and will then draw a straight line between those points. Whendrawlineprompts for user input, Visual LISP turns control over to AutoCAD to prompt for the points. What you see next depends on whether or not the AutoCAD windows are currently displayed on your desktop. If AutoCAD is already maximized, you will see the AutoCAD windows. But if AutoCAD is currently minimized, the windows will not automatically be restored and displayed. Instead, Visual LISP remains visible and your mouse pointer changes to a Visual LISP symbol.

   

   This symbol indicates that the Visual LISP window is no longer active. If this is the case, you must manually switch to the AutoCAD window. Click the AutoCAD icon on the Windows task bar to activate AutoCAD.

7. Respond to the prompts by specifying points in the drawing area or at the Command prompt.

   After you respond to the prompts, control returns to Visual LISP and you will once again see the Visual LISP window.

   When you enter commands in the Visual LISP Console window or run a program loaded from the text editor, you may be frequently switching back and forth between the Visual LISP and AutoCAD windows. Aside from using the standard Windows methods of switching between windows, you can activate the AutoCAD window by choosing Window Activate AutoCAD from the Visual LISP menu, or by clicking the Activate AutoCAD button on the Run toolbar. If you are in AutoCAD and want to return to the Visual LISP environment, you can click its icon on the Windows task bar, or entervlispat the Command prompt or click Manage tab Applications panel Visual LISP Editor. 

You can drag and drop all lisp files to AutoCAD window to work with that lisp.

Once you drag, there is an option for Autoload this lisp always ("Always load this applicartion")

To understand execution command just open LISP file with notepad and you can see lisp command after the text "defun"

in the autocad command line select appload and load any files in the lisp

• Respond to any prompts or dialog boxes that are displayed.
• Start the AutoLISP function by doing one of the following:

1. At the Visual LISP Console window prompt, enter the name of a command or function name in parentheses, and press Enter.
2. At the AutoCAD Command prompt, enter the name of a command or function name in parentheses, and press Enter.
3. If you switch back to Visual LISP before the command or function ends, the mouse pointer will appear as the Visual LISP icon. Switch back to AutoCAD and complete the command or function.
