A perfect surface?

Hey lovely people,

Nice to meet you for the first time.

when I was doing surface modeling,

I have encountered some problems about the surfaces quality with hours' struggling.

The command I tried were Loft in surface and Fill Surface.

Lets take a look at the problem.

I use Loft to form this surface between two flat planes. It was not good. We can see surface of the corner slightly sunken...

So I tried ways to fix it. First, I used Face Curves to substract some curves from the formed surface. Then I deleted the surfaces and build a new surface with those Face Curves using the command Surfaces Fill.

I was very happy with the new surface which looked quite perfect and smooth.

However when I turn on the Curvature Check, it looks very scary....

I am very confused now. Is it a good surface or should I rebuild a new one?

the corner edge is still abit sunken in the picture.... how can I fix it?

Could anyone help?

Thank you!
