Try selecting those surfaces and use Edit/Join to glue them together at their common edges.

If it won't glue together, then that would mean that the edges are too far apart.

Once joined you should get a better display at those areas when you hide edges because the generated meshes will have a unified structure along those edges.

When you have 2 surfaces that are just sitting next to one another but not actually joined, then the meshes that are created from them (which is what you see being shaded there) can have slightly vertex placements there, making it look like there are cracks and gaps between things. But that's just a display artifact from meshing.

Hi Pilou,

Correct - that's why I recommend using Patch in Rhino for this situation.

Your image here will make the same result than a "Patch" or it's an approximation?

It's an approximation. Patch basically works in that same way, but has a fitting process that adjusts the surface to go through (or at least attempt to go through) some curves that you pick.

Thank you BurrMan and Michael for your network-tips. I had already ruled out the idea to make a larger surface and trim it, because all I could come to think of was to make a surface of revolution and then trim that, but that wouldn't have worked for those eight cornerpoints.

The important thing for the surface is really that it's smooth and that it blends together well once you start copy it. And the networksurface seems like it does both.

Thank you very much both of you, I learned a lot.
