I have to make a model of a shape similar to an aircraft cockpit. I have drawn the curves as accurately as I can and they are G2 .The problem is that it seems I only have three curves to use for the surfaces.The best so far seems to be Surface from Network Curves . When I run Zebra to check the surfaces I can see that I get a poor result because of only having three curves .
I have used Surface Tools later to smooth out the shape but the pinch points at each end are still a problem.
I have tried every type of surfacing options and joining / spitting the curves as well. I am probably missing something.
This must be a fairly common problem ,do I need to split a curve somewhere to provide the fourth component perhaps ?
Thanks
