Curved stairs by sketch - weird cropped geometry

[martin_genet]

Hi,

I am experiencing weird cropped geometry on curved stairs with monolithic run. In plan, the stairs show properly, but not in 3d... 
Would anyone know how to solve this? 

Thanks!

Increase the monolithic thickness, it change the bottom to stepped.

Hi @ToanDN,
Thank you for the answer 🙂 it did solve the crop issue.
It is kind of a workaround though. It would be nicer if smooth underside would work.
