Only a small clarification:
-acad.lsp is executed only once per sesion of AutoCAD.
-acaddoc.lsp is executed when you start AutoCAD and every time you start or open a new drawing.
 
By the other hand, you can also create your custom StartUp.lsp where you define S::Startup and control ucs icon and other environment aspects. In practice it's the same as the other archives described by kybluelex and Cad64

Ok, I was thinking of the acadxxxx.lsp, (Replace xxxx with your version). But there are other issues with the acad.lsp that make the acaddoc.lsp more useful, in my opinion. http://usa.autodesk.com/adsk/servlet/ps/dl/item?siteID=123112&id=2897258&linkID=9240617]]> Fri, 09 Jul 2010 16:43:13 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=3970&PID=10166&title=syntax-of-file-acadlsp#10166 <![CDATA[Syntax of file acad.lsp : True, you may lose the file IF...]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=3970&PID=10161&title=syntax-of-file-acadlsp#10161 Author: kybluelex

True, you may lose the file IF you do not keep a copy outside of the standard AutoCAD file structure. Also the ACAD .LSP file is NOT a standard file that comes with AutoCAD, you, at some point, create the file for your use. I have the same file, with changes (which happens very often), that I created while using R9. Just keep a copy.... just like if you use acaddoc.lsp.]]> Fri, 09 Jul 2010 14:15:39 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=3970&PID=10161&title=syntax-of-file-acadlsp#10161 <![CDATA[Syntax of file acad.lsp : In my opinion, it&#039;s not a...]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=3970&PID=10152&title=syntax-of-file-acadlsp#10152 Author: Cad64

In my opinion, it's not a good idea to edit the acad.lsp file, or any other standard Autocad files. The reason is, if you have to run a repair, re-install or upgrade, the code you add to these files will be lost.
 
Create an acaddoc.lsp file and put your custom code in there. You can put the acaddoc.lsp file in the same folder as the acad.lsp and it will run every time you open a drawing. This file will not be affected if you have to run a Repair, and if you have to Reinstall or Upgrade, simply copy and paste a backup copy of your acaddoc.lsp into the proper folder and you're set.

Hi,
I have done this in the past with older versions of AutoCAD, but can't find my old acad.lsp files.
 
I would like to set a command to off when I open a new or existing autocad file.
 
The command is UCSICON
 
Can this still be done with 2010?  If so can someone help me with the Syntax.
 
Thanks
