This file should not be modified.ДЄcad.lsp The loading of this file is dependent on the setting of theДЄCADLSPASDOC = 0 (default) Loads acad.lsp into just the first drawing opened in an AutoCAD session, and will not load for each subsequently opened drawing.ДЄCADLSPASDOC = 1 Loads acad.lsp into every drawing opened. Most of these files are part of the application itself and hence should not be modified, others however are reserved for user customisation and can be modified and created if they don't already exist.Д«elow is the loading order of the various files that are automatically loaded into AutoCAD, with a brief description about each item:ДЄcad.rx This file loads various ObjectARX applications when AutoCAD is started.ДЄcad20#.lsp This file loads the acad20#doc.lsp file in versions which do not load such file automatically. When the AutoCAD application is initially opened, a number of files are automatically loaded and others are reloaded again when every drawing is opened thereafter. This is a more reliable and п»їmigratable method than using the Startup Suite for the same purpose.ДЄside, note that the acaddoc.lsp is not the only file that is automatically sought and loaded into the active drawing. In this way, most users will utilise the acaddoc.lsp to automatically load custom programs when a drawing is opened, so that such programs are available during the drawing session.

The act of loading a LISP file simply means that the contents of the file are read and any LISP expressions found therein are evaluated by the LISP interpreter. When such a file is found, AutoCAD will cease searching and will proceed to load the acaddoc.lsp file into the active drawing namespace. In more recent AutoCAD releases in which the SECURELOAD system variable is present, only paths which are also listed as Trusted Paths will be considered by this search 1. To provide a little background information on the nature and behaviour of the acaddoc.lsp file in AutoCAD: when opening a drawing, AutoCAD will search the Working Directory (that is, the directory in which the active drawing resides), and all Support File Search Paths (those listed in the Files tab of the Options dialog) for a file with the filename acaddoc.lsp. Save the new/modified file and open a new drawing in AutoCAD to automatically load it. On a new line in the acaddoc.lsp, enter the desired load or autoload expressions to load your custom programs, e.g.: (load 'MyProgram.lsp' 'MyProgram.lsp failed to load.')

If the above expression returns nil, open Windows Notepad (or other plain text/code editor), and create a new acaddoc.lsp in a Trusted AutoCAD Support File Search Path. If this returns a valid filepath, in the steps that follow, navigate to the filepath and open & modify the existing acaddoc.lsp using Windows Notepad or other plain text editor. To do this, open AutoCAD to a new blank drawing, and type at the AutoCAD command-line: (findfile 'acaddoc.lsp') To load programs using the acaddoc.lsp, perform the following procedure:Д¬heck whether or not an acaddoc.lsp already exists. Assuming that you are using the Startup Suite as part of the APPLOAD command dialog to automatically load your 'Startup' LISP program (which then subsequently loads other program files), I would instead suggest using the acaddoc.lsp file to automatically load your programs, as this is a far more reliable loading method.
