How to model a freeform spherical structure?
I want to create a sphere with a very freeform structure, with the same sort of pattern as in this 3D printed cast:
I am using siemens nx 9 and have tried creating a sphere and a sketch with the pattern I want mapped over the sphere so I can subtract it from the sphere. I have tried using wrap/unwrap tool which works very nicely for simple curves like cylinders but not complicated curves like a sphere.
What is the easiest way to achieve what I am looking for? Any feedback would be great!
