The way I have done is to build 1/4 of it using curves, then use those curves to create a surface. Once you have 1/4 surface, you can mirror the surface to get 1/2 then mirror again to get the whole. Then merge the surfaces. Once merged, you can solidify or add thickness as needed.

Here's one approach:

2X conic sketches

rectangle boundary blend trimmed back

4 sided boundary around perimeter

Hi Steven,

i've taken your file, reduced number of sketches, added normal and tangency costraints to boundary blends and substituted style feature (requires license) with a simple boundary blend.

Take a look if you're interested. Creo 3.0 file attached.

Probably not blended as nice, but since there is nothing defining that in the original post. IT'S PERFECT!

Attached is my effort to model this by creating one corner using boundary blends and then 2 mirrors to get the entire part. I added some intermediate curves in both directions to help control the blending and eliminate or minimize any ridges. I have not used style features so did not attempt using them to possibly improve the smoothness.
