Great video tutorial Paolo! I will prove it on the real world immediately.
Thanks a lot for your attention and dedication.


Many thanks Paolo. Where can we download the Case 05 - Create list definition by CSV?

@enrique.sg you can access to the Civil 3D Futures Portal, under the dedicated Dynamo forum. This is the link for you to subscribe Click here to join the Autodesk Civil 3D Futures Program

Once you are in, you can visit this thread to download the dataset LINK

Hi Paolo, great that you shared the datasets from the webinar. I’m trying to create the Rail Cables using your script but combined with the Rail dwg it doesn’t work. I think the problem is in the units in the DWG, it’s in FEET. Do you also have a METRIC version available?

Here is the problem using imperial stationing and the node is seeing these values as text instead of double numbers?

Drop the “+” and replace it with nothing. Then convert the string to double.

Thanks Keith, It’s working perfect. Nice!


Has anyone here got the sample scripts yet which were shown in webinar and discussed that scripts will get shared after the webinar ?

Ciao Paolo,
i downloaded dynamo samples for c3d version 2020. i’ll ask you 2 things:
-using AutoCAD_Python_PSet_DumpPropertySetDefinitionsToJSON.dyn no information of the lists is exported. Is it correct or am I wrong? I’m not getting any errors?

  • among the shared samples is there no more “create list from CSV”?

thank you in advance for your reply,

@davide.clauser I’ve updated the definition of the Python module in the Civil 3D Beta forum hoping that it would picked up by the product team…pset_utils.py (20.6 KB) pset_serialization.py (5.5 KB)

Thank you Paolo… everything is working well. I really appreciate what you do to share knowledge on c3d

Hi Paolo,
i downloaded the dynamo samples and replaced the old pset_utils.py and pset_serialization.py.

  • using AutoCAD_Python_PSet_DumpPropertySetDefinitionsToJSON.dyn the information of the list is now getting exported as intended!
    Now i used AutoCAD_Python_Pset_CreatePropertySetDefinitionsByJSON.dyn. The PropertySets got created but the list didn’t!
    I didn’t get any errors! Do you have an Idea why this is happening?
    Is there a new Version?

Thanks in advance for your reply

AutoCAD_Python_PSet_CreateListDefinitionByCSV.dyn (5.8 KB)

In this video you mentioned that the PropertySet to JSON Dump does not support formulas but might in the future…is this now supported?

Hi Paolo

Where can we download OCS_CHAT_RAIL.csv for Rail?
