CADFEKO subtract

In the attached model, subtract operation does not generate the expected surface. Can you please have a look at the model and let me know how to resolve this issue

If I make the offset 1e-5 m, it still works. But at exactly the coordinates you want, it does not work.

Note that if I use Feko version 2021 and convert the cylinder to primitive and then subtract it works without any offset. But this does not work in 2019.3 that you are using.

Please confirm which surface you want to subtract from which?

I had a quick look. The cylinder can be subtracted from the surface if the cylinder is moved 1 cm into the negative X direction. Also then the surface can be subtracted from the cylinder.

Thanks for your quick reply. I would like to subtract the 'GeomImport1' surface from the cylinder. I am trying to generate an offset reflector. Imported surface corresponds to the shape of the reflector

I works when the cylinder is moved 1 cm into the negative x direction, but I want the cylinder to be centered at the coordinate mentioned in the model. Is there an alternate solution that works without shifting the cylinder center?
