Pls help me
All the labels in civil 3D are scaled per Freeport scale or If in model space per drawing scale. If they look big, regen the drawing and they should be the correct size after the regen. If they are not you may want to check to see what your viewport scale is set at.
You would also want to make sure that in your styles that the text size is set to what you want, real world. Text will scale per your drawing or viewport scale.
Freeport, Long Island is not far from me , and they do have some fairly large signs
We're in Kentucky? good luck
