Can someone explain to me how to make these surface lattice patterns?

@Jimbo_Jombo

but it doesn’t give this same kind of flowing form.

Not sure if you must copy that design or simply using as reference—just in case here’s a simple ‘contour’ alternative to keep you from trying to imitate; define your vector(s) and generate your own lines:

*Edit:
Also, it seems you started with something related in your other thread?

I’m surprised nobody warned you about multiple threads for the same project. Anyway, for diagonal lattices (not the same as flow lines) also see these potential approaches, second link shows another nice example by @jessesn:

Uniformly orienting mesh faces by vertices

You were still missing the curves you’re morphing. But I think you got it Rather than quad-remeshing your SubD, I think using MeshFromSubD might be convenient to stay closer to the original smooth form? Just pay attention to the ‘D’ level so it’s not heavily subdivided prior to box-morphing the lines you’ll turn into multi-pipe. Alternatively, you could keep the mesh pretty coarse but make your line pattern more dense before you box-morph to find the right balance. Very easy to …

Difficulties in modeling shoe models

Hello everyone, how should we model this shoe model? It has the same mesh division inside and outside, which is very clever but also very difficult. Can you help me come up with ideas on how to model it. [05] [04] [03] [02]
