Create a bridge through a 2D family and axis


first I want to thank you. This page has helped me a lot.
There are several ways to model a bridge. One of them is by 2D family and axis. There are several examples of this on this page.
e.g. Consider Superelevation in Bridge Design

Although it explains everything in this example, unfortunately it doesn’t work for me. I try to model the bridge with the uploaded file but it doesn’t work.

Could you please let me know what it could be? is there a problem with the dynamo code?
How do I model a bridge through 2D family and axis?

I am very grateful for the answer.

Best regards


Maybe take screen shots of your dynamo graph?
