Greetings,

I've created fan blades using BRepOffsetAPI_ThruSections. I then transform them using BRepBuilderAPI_Transform to place them radially.

I observe that the fan blades I initially create are smooth and the surface is ready for CFD analysis after STL export. However, when I transform the blades, I find that the surface is now damaged.  Pls see attached picture.

Could you kindly give me insigths into why this happens and how I may prevent it ?

Regards,
Pranav
