Hi. I am trying to change the surface style from [0.1m and 0.5m] to [1m and 5m] and I found the node who is supposed to do that (DocumentExtension.SetStyle from the 3DCivilToolkit package), but it doesn’t seem to be working and I cannot understand the error message. Help, please ?

Regards,  
Paul

Hi @pmit,

Seems to be working here, check your Civil 3D Toolkit version (mine is 1.1.26 on Civil 3D 2020) and try again.

Hope this helps,  
Assem

Civil3DToolkit version is 1.1.28. Dynamo version 2.4.1. Civil 3D 2020.  
So, it’s not that.

Hi @pmit,

That warning means that Civil 3D needs to be updated. Make sure you have the latest updates installed.
