Making this roof smooth

[skyice]

you can use blend surface tools!

and key "P"

choose X-axis or line .

I tried.
I sure it can be G2 surface!

join command
:)
then i also extracted a few key iso curves from all surface shapes,extracted edge curves guides and rebuilt it as a patch surface to one piece...much smoother final result.

I joined all the surfaces but when I am trying to extract the iso curves I have to select individual surfaces again (it's like the surfaces are unjoined, is it suppose to do that?). I managed to patch the surface and mirror it, but another problem rise up. The mirrored surface has a kink or seam in the middle, so I tried to use the pipe, split, blend and networksurface method. But there are holes between the surfaces.

Ah...after all this typing, editing picture, and upload. I solved the problem after I post it :p

I joind the surfaces and the holes are gone :)

Do you have to always use the fillet method everytime you mirror parts? Or you guys have a different method of doing it?

ah well ..when you use the join command rhino will "join' two or more surfaces together
that are within the tolerance settings..if the tolerances are set to say 10.0 and you parts are 20.0 units apart then no joining will happen,but if you set the tolerance in the units settings at 20-30-100 whatever then almost everything will always join if the parts are that close in units.
The thing that join does is match up the edges to a joined common edge,ultimately it is not
a single surface but a combination of surfaces,so yes you will have to select the surfaces
individually...annoying i know.
What you may want to do is basically use the outlines/borders/edges and extracted isocurves to have ribs as a frame so you can rebuild to a single smooth shape/patch.
