Hi,
upon trying to create a neck detail for a bottle I could not get Sweep2 to work very well.
I eventually used NetworkSrf which gave a satisfactory result but I was hoping for some help from the group.
(a) why wont Sweep2 work
(b) are these two methods the way to build that surface
You’re making this way more difficult than it needs to be. Keep things simple use single span surfaces. Avoid networfSurf, it might look ok until you check it with a curvature graph. The true power of Rhino is in point editing surfaces.
