acaddoc.lsp - Question
Will the acaddoc.lsp run in any folder, or just in folders defined in the search path. My assumption from reading the documentation is that it does not need to be defined in the search path. The only requisite is the acaddoc.lsp file and the .dwg file need to be in the same folder.The reason that I ask is that on AutoCAD 2018 does not run acaddoc.lsp like the earlier versions did (2014 & 2016).
Can anyone confirm or correct this?
Greg It might be due to the security settings Autodesk has been adding ( TRUSTEDPATHS, SECURELOAD etc. ) The support paths are checked first and if I remember right once it finds one it stops searching. I have to admit, I was skeptical when I read your post. Things rarely change with AutoCAD/Autolisp over the years, or at least I would have thought I would have remembered this.
But after some testing, I agree.
Given an "acaddoc.lsp" file in the drawing folder, in AutoCAD 2016 and lower, it does get loaded, regardless of the existence of any other "Acaddoc.lsp" file. Presumably because AutoCAD is considering the drawing folder at the TOP of the support file search path.
On 2017 and later, it does not load the "Acaddoc.lsp" file from the drawing folder. It loads the first one it finds in the Support File Search Path (presuming there is another one). This makes me think it's no longer considering the DWG folder to be at the top of the support file search path.
An old trick is to run the -INSERT command (note the hyphen), and then enter a bogus string (EXAMPLE: "gsdfg543casdfas" ) for the block you want to insert. AutoCAD will respond with a message dialog stating that it can't find "gsdfg543casdfas" in the search path, and then list all of the search paths. The listing of the search paths has not changed in 2017 and later however. It still shows the DWG folder as second in the list, right above the "Support File Search Path" that you see in OPTIONS.
Looks like you found a bug, unless you can find some documentation on this changed behavior. I know who to ask. I'll report back if I find out something. Thank you, rkmcswain, for taking an interest in this issue and appreciate the information if something is known. I have been scratching my head a few days about it.
Greg Call your acaddoc autoload.lsp and try interested to know, we use this name for our library lisp so never change acaddoc.lsp This is not a bug and ronjonp is correct in mentioning the TRUSTEDPATHS variable.

The answer came back pretty quickly and they were simple fixes:
LEGACYCODESEARCH set that to ON
SECURELOAD set that to 0
Once I set those then all was golden again.
Thank you for all the comments.
Greg With a little reading, you could have saved you & your reseller some time -
