After a long hiatus, AutoCAD returned to the Mac platform in 2010. Many features were reimagined or entirely rewrote. Every year the product is improved, but Windows users can still find the Mac interface and toolset a bit jarring. This is a 'Best of Lisp' collection containing 13 lisp routines. Various different Lisp routines from a lisp that opens windows explorer to the current drawing directory, to a lisp routine that rotates a selection to a entity of your choosing.

Solution:

To have AutoLISP routines load automatically, either add them to the AutoCAD Startup Suite or use the acad.lsp file.
Add to the Startup Suite

1. Run the APPLOAD command.
2. Under Startup Suite, click the Contents button.
3. Click the Add button.
4. Browse to the location of the LISP file, select it, then click the Open button.
5. Once all of the LISP routines have been added to the Startup Suite, click the Close button.
6. Click Close again to close the Load/Unload Applications dialog.

Use the acad.lsp file
The acad.lsp file is always loaded when AutoCAD starts up. If a special function S::STARTUP is defined in the acad.lsp, it will be executed.

For example, there are two AutoLISP routines named stair.lsp and wall.lsp to be loaded each time AutoCAD is run. Create an acad.lsp file that contains the following lines of code and place it in the AutoCAD support paths.

(defun s::startup ()
(load 'STAIR.LSP')
(load 'WALL.LSP')
)

If wall.lsp and stair.lsp are in the AutoCAD search path, they will automatically load. If the AutoLISP routines are not in the AutoCAD support paths, include the full path within the acad.lsp file. Use either '/' or ' as path delimiters. With the same example, the acad.lsp file would look like this:

(defun s::startup ()
(load 'C:/PROG/LISP/STAIR.LSP')
(load 'C:PROGLISPWALL.LSP')
)

If the S::STARTUP function is defined like this, problems could arise if other applications use the S::STARTUP function as well (for example, a third-party plug-in). To ensure compatibility, append the code in case there is an existing S::STARTUP function. To do this, add the following code to:

(defun mystartup ()
(load 'C:/PROG/LISP/STAIR.LSP')
(load 'C:PROGLISPWALL.LSP')
)
(if s::startup
(setq s::startup (append s::startup (quote ((mystartup)))))
(defun s::startup () (mystartup))
)

Note: Using an acad.lsp file runs each time AutoCAD is launched. An acaddoc.lsp file runs each time a drawing is open.

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.

   Icom ic-t90a manual pdf. INSTRUCTION MANUAL WARNING: MODIFICATION OF THIS DEVICE TO RECEIVE CEL-LULAR RADIO TELEPHONE SERVICE SIGNALS IS PROHIBITED UNDER FCC RULES AND FEDERAL LAW. Thank you for purchasing this Icom product. The IC-T90A MULTIBAND TRANSCEIVER is designed and built with Icom’s superior technology and craftsmanship. With proper care, this product should.

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.

Example

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

Lisp Programs For Cad

1. In Visual LISP, click File Open File.
2. In the Open File dialog box, browse to the SampleVisualLISP 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 the drawline function from the Console prompt by entering the function name in parentheses, then pressing Enter:

   The drawline function will prompt you to specify two points, and will then draw a straight line between those points. When drawline prompts 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 enter vlisp at the Command prompt or click Manage tab Applications panel Visual LISP Editor.
