Use this file to enable automatic loading of the 2D or 3D lisp files.
After unzipping, this file can be opened and edited with Notepad. 

To make it work, you will have to download and save the free lisp files from this site to
a directory called c:\BilroCad.

You could download it to another directory, for instance c:\cad\bilrocad. 

If you did this, then you need to alter the directory in the acad.lsp file to c:\cad\bilrocad.
(Hint: Use the Replace feature of Notepad)

The Acad.lsp file should be copied to  the Support directory of your
Autocad installation, for instance c:\Program Files\Autocad 2008\Support.

There are some who say the proper name for this customisation file should be
Acaddoc.lsp.  I suggest you have a look at the Help file of your particular version of
Autocad and study the difference between Acad.lsp and Acaddoc.lsp. There is no
harm in renaming it Acaddoc.lsp.  

If you are on a network, and do not have access to your C: drive, use this method to
have it as your startup file:  Go Tools/Load Application, and Press the Button
marked Contents under "Start-up Suite".  Just browse and add it there.


1. As I have said above, you can copy the Autolisp files to any directory of your choosing.
But you must be aware that you have to add this directory location to your autocad path, 
otherwise, if a routine uses a dialog box, it will not work. To add your directory to the path,
 in Autocad go Tools/Options/Files Tab/Support Directories, 
and add it in there-you need to hit ADD then BROWSE. 

The only file posted as at June 2009 that uses a dialog box is Fast.lsp, but more may be 
added in late 2009.


2. Some of the routines need to set to different layers in the process of doing their thing.
I have inserted a routine called LAYSET.lsp - see Layer Tools.
Open up layset.lsp with notepad and you should be able to follow it as it just issues standard
autocad commands.  I use this all the time and it causes me no problems, as it just creates
variables laymedium, laydim and so on, which only last as long as the drawing session.


The big advantage is that IF YOU ARE OFTEN CHANGING LAYER NAMES AND COLOURS, YOU DO ALL YOUR
CHANGES JUST ONCE, BY EDITING LAYSET.LSP
