Civil3D Surface Icon Diffrence

[bijoyvm]

hi all,

Could you please let me know the difference between these two icons? Both represent Surface files, but some appear in blue while others are normally grey

 

Thanks

I have moved your thread to the Civil 3D & LDD Forum. Please post in the most appropriate forum.

 

What version are you using? Looks like new to 2025 Civil 3D.
