Hi all,

I’m trying to revamp the sample graph from Dynamo 2025 that is named “Rotate Structures Along Alignment.dyn”

I’d like to adjust depending the different structures name because the rotation isnt the same depending if it’s an “Elbow 45”, “Elbow 22.5”, “Fire Hydrant” etc …

I’ve been able to filter a bit with “AQUEDUC” (means water in french) but I’d need to define more precisly the part size name

I’ve been browsing the available nodes and cant seem to pull out the one i need.

And i think that i need to understand the hierarchie of the data

Example :  
Pipe Network  
-Structure  
-Pipe

PartFamily  
-PartSize

Tia Dynamo community for helping a newbie out 🙂

I did manage to find a way to fetch that data but with the “Description” with CivilObject.Description :
