Have you ever opened a Civil 3D drawing and there were warnings all over your drawing like the below screen shot?

Some of you may have realized that they size relative to the screen. So, if you zoom in and do a REGEN, they resize to your zoom level like shown below...

What exactly are these warning symbols?
These are warnings that show when the content of a label was changed. It does not plot and is only for informational purposes. The problem is, labels change constantly. So, that means you are ALWAYS going to see these symbols.
How do you turn these labels off for good?
Very easy. Navigate to your OPTIONS. Click on the AEC Editor tab (the very last tab). Uncheck Drafting under Solution Tips.

That's it! No more pesky warning symbols. I hope this helps!
