I'm having trouble creating good surfaces for a fan shroud. It is for converging from a rectangular duct to two side by side axial fans.
First problem I am having is getting second order (C2, G2...) contious surfaces. What's the best method for this?
Second problem is creating the saddle like surface between the two axial fans. Have tried various approaches, but no can do.
Attached is an image of the curves and a couple surfaces I have been able to create (though not C2 surfaces). Also attached is the Creo Parametric 2.0 file I've been working in which should make it fairly obvious what I'm trying to do.
TIA,
