Hi Mark, definitely like Steve mentioned it would help a lot if you could post the model file with the curves in it.

From the look of it, the most likely problem is that your curves don't have a full grid layout.

Most of your curves do, but probably the curves around the outside are breaking up the layout.


For Network to work properly, the curves involved must form a kind of 2D like grid sort of like latitude and longitude lines.

If those are 2 curves around the outside that touch each other at a point, then all the interior curves should also come to the same point to make a kind of "pole" region there (kind of like where longitude lines converge at the pole of a globe). Something like this:




You can't have just the 2 outside curves touching at a pole only and not the others.



The other type of layout which may work better, is to do a kind of extended grid with sharp corners, like this:



Then trim off the exterior of that surface with a rounded outline to make it roundy, that can be a more controllable than trying to construct to the final rounded exterior outline right from the beginning.
