How to change Pipe Network Pipe Material

Hi, since i updated to Civil 3D 2025.1 i notice that the pipe material we have as just HDPE on the labels is now showing as Corrugated HDPE Pipe. and won’t let you just fill override the Material by just going into the property of the pipe and just type it in. I have to revised the material pipe catalog to add the HDPE options as well and works well to set this from the beginning on a new network but for other projects with the previous setting i still get the network now showing as Corrugated HDPE Pipe. doing a global change on the drawing using the Project Explorer doesn’t work for the materials so i think i can try on a Dynamo script to fix it but in don’t see where i can set the material. i am stuck right now on that part. Please advice, thank you.

Hi @csanchez-jmc,

The material value is typically read-only, so I don’t know if Dynamo will help here. But you could try working with the part data using these nodes:

You could probably swap parts to a pipe with a different material, just another way to look at it

Thank you Zachri, those nodes do the trick
