; error: no function definition: ACET-AUTOLOAD2

[dvertz]

I just setup to use Civil 3D 2025 and I am getting this error "; error: no function definition: ACET-AUTOLOAD2". How do I fix this?

Hi @dvertz Can you share a screenshot of this error? 

I'm trying to see when you're getting this exact error.

Was this as download installation or deployment?

mdavis,

This was a download installation. It is right after Civil 3D is fully loaded. Strangely, I have not found a command in the Express Tools that isn't working as it should. Yes, the Express Tools menu does get loaded. After doing a bit of research, I found this particular command was introduced in 2004 and autoloads the some if not all Express Tools commands.

Thank you ... I'd like to recommend doing a Reset to Default.

Save the settings.

Please make sure all of the updates for C3D and AutoCAD are installed. Then let's reboot, start C3D, don't add the restart of the software. See if you still get the error.

Handjonathan,

I did not use his suggestion as I already have the program customized to my liking. Doing a reset would kill all that work.

I found a work around that works for me. I added this code to a file that loads when Civil 3D starts:

(if (= 25.0 (atof (getvar "acadver")))
  (progn
    (if (findfile "acettest.fas") (load "acettest.fas"))
    (if (findfile "acetauto.lsp") (load "acetauto.lsp"))
  )
)

Hi dverz

Thanks for your solution, it helped me a lot.

I used parts of Flatten for a program written for 2024 and found that (load "flatten.lsp") triggered the mentioned error message in 2026.
