Unable to add floor with Ellipse curve

Hello, I wonder if it’s really a limitation or I add a wrong input.

Referring to the screenshot below. I found that some closed curves are not allowed to create floor in Revit such as Circle and Ellipse shaped curve.

Also if anyone have idea to add this shape outline as a floor how could I do that. Thank you for any suggestions in advnace.

Hi @kian.jansuwan

I just quickly tried adding floors with a circle and an ellipse and it works fine for me. Could it be because of the input that you are using? I created the circle and the ellipse using GH components.
