Hello everyone, I’m new to Dynamo and currently trying to follow a YouTube tutorial on importing Excel file data into Civil 3D, creating a point group, and then generating a surface.

I followed the sample file “OpenXMLImport_Data From Excel.dyn”, and now I am getting a different set of errors. It seems the graph is running further than before, but it still does not complete successfully. I may still be missing something in the configuration. I have attached the updated Dynamo f…

Pin open the data preview from the excel node and the list transpose node.

By the way, if you want to keep your data in a .txt file, you can parse it into values using the below method.
