Curve Network _NetworkSrf does not closed

I can’t undestand why this happens, the network does not closed

Thanks for support

Network surface can’t make closed surfaces from curve networks.
What’s the end goal of the shape you’re building? It seems more suitable for a SubD based workflow.

It’s a shoes, thank you for your replay,

Correction to my previous post:

you can create closed network surfaces, but then the curves in one direction all need to come to a point.
You have two problem areas:
At the back of the surface your curves are overlapping:

these two curves don’t end in the same end points:

That curve network doesn’t have intersecting curves… but regardless of that, how did you derive those curves from a section of a mesh or a shape? What are you basing them on? Without an underlying form, I find it hard to create something realistic.
Example in an industrial use case: for actually engineering a platform sole and heel—not for didactic or academic purposes.

I’m just testing from this reference

If you want, I can provide a real shape. This drawing isn’t useful and only creates confusion—feel free to discard it. I can share a real pump (décolleté) shape so you can start from something concrete.m something concrete.

@Danilo_Pasquali You can use these two shapes—they’re generic and don’t reference any fashion brands. They’re a solid starting point to practice from. Good work.

If you don’t know this command, you need to learn it. If you already know how to use it, you’ve already done half the work.

These things are not even remotely realistic for a shoe. This is the kind of work you typically see from game modelers. In fact, most of the shoes you find on platforms like ArtStation, or in tutorials on YouTube and similar, are not realistic. They may work for a videogame, but not in real-world production.

Great! Thank you so much, i appreciated. Thank you thank you than you, i can training with something real
