Support structure not visible on Cura

[markstruct 0]

I tried to play with the support structure settings, and Cura seemed to be responding to the change of settings as it was recalculating the print duration. However, why I could not see any support structures created on-screen on Cura? Is there no preview of support structures? Thanks.

Support Structures are visible in the 'Layers' view, not in the 3D model view.
