With this knowledge one can edit or create an ACADDOC.lsp to include any AutoLISP expressions to be evaluated upon startup. If one or more such files are found, AutoCAD will proceed to load the first file found. Upon opening a drawing or starting a new drawing, AutoCAD will search all listed support paths including the working directory for a file with the filename: ACADDOC.lsp. For these reasons, I shall introduce another method which, although requires the user to have some basic knowledge of AutoLISP, overcomes these difficulties. There have also been a few known bugs surrounding the Startup Suite in past versions of AutoCAD. The method of using the Startup Suite to load programs automatically does have a few disadvantages however: should the user wish to migrate his or her programs to another computer, all programs will need to be added to the Startup Suite on the new computer. In the dialog that subsequently appears, click on the Contents button beneath the Startup Suite heading:Īll programs listed in the above panel will be loaded every time a drawing is opened. This is perhaps the most user-friendly method to automatically load a program at startup, as the user needn’t have any LISP experience whatsoever.įirstly, type AppLoad at the AutoCAD command-line (alternatively, go to Tools » Load Application). Thankfully, I shall introduce two methods to accomplish this task, each with their own advantages in different situations. If you have a toolbox of LISP programs that you use regularly, it would be tedious to have to load each and every program whenever a drawing is opened. This tutorial aims to guide you through the various methods which can be used to load a program automatically on startup. When the command syntax is known, it may be typed at the AutoCAD command line to invoke the program. If the c: does not appear after the defun function, this indicates that the function is a subfunction and is designed to be called from another program. In the above example, the command would be M圜ommand. The syntax will be located after the c: in a defun function call, for example:

If it cannot be found in either of these locations, you can inspect the source code itself to determine the command to use. The syntax (command name) to call the program may be displayed in the author’s loading messages, or perhaps noted in the program header. If the program has loaded successfully, you can now proceed to run the program in the current drawing session. Now go to Tools » Load Text in Editor (alternatively, Ctrl+Alt+E) Running the Program

In the window that subsequently appears, go to File » Open File (alternatively, Ctrl+O), and select the previously saved file. To load a program using this method, type VLIDE at the AutoCAD command line. This method is aimed primarily at developers, as the VLIDE offers many debugging utilities when writing & loading code. Method 3: Using the Visual LISP Integrated Development Environment (VLIDE) Note: if using this method to load many LISP files on startup is causing drawings to open slower, refer to my tutorial on the use of AutoLoad to demand load LISP files. When finished, open a new drawing and the LISP files should load.

If the LISP file does not reside in the AutoCAD Support Path, a full filepath is needed so that the LISP file may be located in this case, be sure to use double backslashes when specifying the path. ( load "C:\\MyFolder\\MyLISP.lsp" "MyLISP Failed to Load" )
