Default Attaching Surfaces

Hi
I am doing a model for one of my courses and I was trying to Attach two surfaces and I couldn't.
The reason is, one of the surfaces is a lofted one from 2 curves and the other one is a planar (trimmed surface)
how can i attach them?
do i have to convert one or both surfaces into some other surfaces?

ALso, I have a little problem when it comes to rendering the image.
In the Render Globals, I've set everything as Production Quality, using raytracing, etc, etc.
But the final image is not accurate. Curved surfaces don't look smooth as I would like them to be. The look like polygonal surfaces.
I tried rebuilding the surfaces with more spans more but the final rendered image still not smooth.

What can I do for both situations???

Please, I would appreciate any help, since I am doing this model for school.

Thank you very much.

The planar one at least should be rebuilt. If you have different U/V spans I'd recommend rebuilding both to have matching spans. The problem with be planar is the history attached due to construction history. The loft has it's history too, but it's more forgiving. Once you try to attach to the planar surface, odds are you break planarity and hence have no surface.

As for the render, can you post it for troubleshooting?

trimmed surfaces cannot be attached.
