Simply placing rebar in concrete beam

Hi everyone, I’ve been trying to put a rebar in the middle of a concrete beam using Dynamo node Rebar.ByCurve but it doesn’t seem right!
Here is my dyn file.
Could you guys help me with this problem. Thanks guys!!
Rebar.dyn (26.7 KB)

In dyn file, there are 2 nodes select face, choose 2 opposite faces like the image above! Thank you so much!

what errors do you get when you run the script? which version of revit?

This is the error:
I’ve been using Revit 2018, Dynamo 2.0

The problem was your Python script, why don’t you simply use Line.ByStartEndPoint node?

Can you post a screenshot of your graph?

Try to update Dynamo for Rebar package. I have version 2.0.2.
