Hi Michael,

Thanks for the advice - what I am using the shell for is to run a RHINO plugin called ARMADILLO which maps tiles onto the UVs surface and requires a seamless continuous untrimmed surface. Here is the surface I generated in RHINO and the plugin effect over the surface so you can see why the continuity is important.

Also I thought with Network Curves and loose option if points dont exactly meet it does a loose skin.
