Thanks Michael, now I understand it, and now the Network tool works for me! :-)

Yes, I did read the documentation before posting as suggested by Frency Pilou. I also searched the MoI forums and tried to google an easy explanation on "Coons Patch" but I just didn't get it, until now... Sorry.

The Network tool seems fairly powerful actually. It gives me some more freedom to sculpt but can I add control points (including new corners) after the surface has been created?
