Hi, i am trying to make a Dynamo graph to change the material of all the pipes but its not working. i am not sure what i am doing wrong. [image]

@csanchez please look in the %temp% folder for the “Autodesk_Civil3DToolkit.log” file for that session and post it here, thanks.

Sorry, for the delay Paolo. i was out the last couple of days. here is the log file. i tried with a different project with the sae result.dynamoLog_8fe7f2f7-0049-4b2f-8b8e-8463bc0246b6.txt (7.4 KB) [image]

@csanchez I mean the Toolkit log in your temp folder

Paolo, where that would be located. i don’t see different types on the folder other than dynamolog_…

type %temp% in your address bar, if you cannot find it it means that there is no exception caught, which is not so good because then I cannot help you

found it. i change the extension to be able to uploaded. Autodesk_Civil3DToolkit.txt (4.5 KB)

If you open it you will see that it says “ERROR: the PartDataField is null”. This is because it could not find the name of the parameter you wanted to change in the Part Data. In particular, the name you should be using is one of the keys in the output dictionary out of the Part.GetPartData. In your case it is called “Mat” and not “Material”. Also, the Pipe.Material and the PartData Mat are absolutely two different things (I know, it is confusing) although they report the same value. In any case the property is read only and cannot be changed.

Paolo, i changed but still have issues. Autodesk_Civil3DToolkit (2).txt (13.3 KB)

yes please read my answer above

[image] Paolo_Emilio_Serra1: read only and cannot be changed how about using the description instead. i tried the input as Description and the value remains the same
