Thanks for the help!

 

I have an older version here, so maybe it's different now, but I assume there's a header with some information, which you should read carefully.  At least in some earlier versions, it is not recommended to edit the acad2xxx.lsp file, but there isn't an acad2xxxdoc.lsp file until some later version than mine, so maybe it's okay to edit that.  If so, yes, you can just add that line anywhere other than inside some other function in it.  If it's not recommended, and you don't have an acaddoc.lsp file already, you can make one, in some folder that's in your Support File Search Path list, even if it contains only that one (autoload) function -- you'll develop other things you want to put in it.  It is run every time a drawing is opened, so things in it are available in all drawings, and maybe that's done with acad2013doc.lsp, too.  The issue is that some related files, like the one you probably have without the doc in its name, may be loaded only once when AutoCAD is started, and not with every drawing that's opened, so commands defined in them won't necessarily be available in all drawings.  So read up on the files and which are loaded when.

So that command can go anywhere in that text, as in right at the bottom?

 

Save the file into some folder in your Support File Search Path list in Options.  Type APPLOAD [or just AP], navigate to that location, and load it.

 

If you include this line:

 

(autoload "ByLayer" '("BYce" "BYs" "BYall" "BYevery"))

 

in your acaddoc.lsp file, the commands it defines will be available in any drawing, though the file itself will not be loaded unless and until the User enters one of those command names.

 

You can also make toolbar buttons or other kinds of menu items to invoke the commands.  For instance, to return all current-entity settings to the defaults, you could make a toolbar button that contains:

 

^C^CBYce

I'm trying to create a command that will change THE SELECTED object(s) to ByLayer for Color, Linetype, and Lineweight.

Doing so also loads the command line shortcuts you defined within the .lsp

So to get this onto a toolbar, I'd just have to manually add it through customization.

Thanks for the help!
