Can you featurise a corridor using code c#

Hi there,

I am trying to featurise a newly created corridor which I have created using code in c#. I want to featurise it however I am unsure how to do it. I have added

newCorridor.FeatureName = "Name";

but this still shows up as NotFeatured in the Open Roads dgn.

Any idea how can I acheive this?

Thanks
