I have seen, and received questions, about this same "feature".
If you have a non-annotative dimension style set current, and change the Civil 3D scale, it creates a <style override> and sets that as the Overall scale in the Fit tab of the dimension style.
I've had clients complain about that behavior, but haven't figure out why it does that to a non-annotative dimension style, or if there's a fix.
Not much help...

Autocad dimstyle overrides should only be triggered when dims exist in the file with manual overrides. Stop/remove the overrides (Dim Update command) and the new overrride style should not be made.
Please note my use of the word 'should' in all of my posts. I am aware that in the AutoCad world 'should' happen does not mean it actually happens. 😮

Thanks for the reply John,
I've gone through this many times to confirm.
Although AutoCAD "shouldn't" it creates a Dimstyle override , in a non-annotative dimstyle, anytime the C3D scale changes.
Not sure if this is "as-designed" or how it's procedurally explained.
See a screencast of what we're talking about.

I always have non anno styles current and have not seen this. I am wondering if it happens in an empty dwg. Nothing in it but the non anno dim style, set current. No dim objects drawn anywhere in the file.
