How apparent profile are rendered in Revit


I have a model that used to look okay in Revit, but then I rebuilt it with better original curves (more accurate) and it stopped looking good when imported into Revit.
See image.

I have also attached the two models from Rhino, the one that renders properly and the one that does not.

We need a scientific way (reproduceable) to tell which geometry will render correctly in Revit.

Does anyone know?

Thank you!
