Rendered 3D Solid Arch Displayed as Straight Segments

[rhw]

See the attached preview image from the cloud render.

Notice the green railing on the bottom right, it's arcing fine. The pedistal it sits on which is a simple 3D Solid rectangle sweep, as well as the sidewalks, rendered in straight segments as apposed to arcing. My goal is for the pedistal to follow the same smooth arcing shape as the green railing. In AutoCAD Architecture model space, it arcs perfectly fine, but then shows up as straight after the render preview.

Any help with this will improve my workflow. Thanks.

Try increasing the values of FacetRes and ViewRes system variables and see if it improves the smoothness of the rendered object.

Spectacular. Thank you.
