Dynamo for Civil 3D 2025.2 Release

Civil 3D
26

Hi,
it’s annoying that the new version doesn’t provide backward compatibility. I have scripts created based on Civil3DToolkit. The nodes I used are no longer available, and no replacement is provided, for example DocumentExtension.GetDocumentStyles. I used it to create custom lists with the Data-Shapes package because the built-in lists are insufficient. I think Dynamo from Civil 2025.2 is a change for the worse, and I don’t understand why there is no backward compatibility provided. Now I have to change all the scripts I created, which is frustrating.

There was a post about this package a while ago, there may be OOTB nodes that could easily be replaced.

Future of Civil 3D Toolkit and Camber Packages - Civil 3D - Dynamo

A post was split to a new topic: Pick Point node values seem incorrect

Did you ever find a replacement for the missing DocumentExtension.GetDocumentStyles node?

I created a Python script with ChatGPT’s help

Thank you for sharing this code. I’d like to know what prompt you used for ChatGPT. Also, do you know how to apply the band set styles to the profiles after retrieving the style names?
