How to create a ships hull as a single surface using Curve network

[alanem]

Hi all, I’m trying to make this ship hull as a single surface using curve network, but cannot make it work using both U and V directions; it works as one or the other, but is giving me errors whenever they are combined.

I have tried to split the single keel curve in two in the hope that it will read in the U and V calculations but no joy there either.

Also tried the Sweep 2 Rails option, but doesn’t give me the surface I’m looking for…

Any assistance / suggestions would be appreciated!

I’m not sure if that’s what you want, and just fyi.

Thanks Jessesn, yes that is what I’m looking for… when I try to replicate what you are doing, I get the same fail notice as before - hopefully the video I shared is useful

Please carefully watch the video I provided and note when the selection of the vertical curve ends.

This is becaue the NetworkSrf has specific requirement for curves in the U and V, and curves in the same direction cannot intersect themselves.

Only able to do the red section using NetworkSrf - did manage to do the rest of the hull using Loft and MatchSrf. Dont want to change the hull curves too much as matching to a similar hull shape. Will need to spend more time figuring out Curve networks when i get a chance - thanks for your patience

Hi Jessesn, I did some tweaking on the end curve spline and it worked perfectly as a single surface

Much appreciated!
