3D Rendering and Calculation - Object from Rhino

Hi! I exported an object from Rhino, then converted to SKU then converted the file from .sku to .3ds so I can import to Dialux Evo.

My question is, why does the calculation and rendering look uneven like they have edges when it should be smooth?

Please see attached images for reference.

I have added an image on how its supposed to look.

Thank you for your assistance.
