How to make quad mesh faces follow the mesh edge smoothly?

I have initial surface that I need to convert into quad mesh following Specific directions. I applied isocurves as guide curve so most of the meshing look correct, but I need an edge of relatively smooth row of mesh faces so I could control the width of the edge.
This is a surface representation of the idea.

And here is the mesh result, U and V curves go as they should, but I can’t do anything about the edge which is shattered

Also a small sub-question - why is changing Sliders value doubles the number of the controlled edges depending on the odd/even number? I’d prefer having a linear control

I wonder is this what you want ?

Something like that, but it remeshes the rest of the surface following standard quad remesh distribution (see the 5 faces meeting at one corner in the center). I need edges to go radial (verticalones) and parallel to the xy plane (horizontal).

You can add more Guide Curves to control the final result you want, fyi.

BTW, there is a guide about how to use QuadRmesh..

I tried that prior to making this post, because I got pretty messy results with all input curves together, so that’s why I am wondering if there is a better workaround

What is the Gc (Guide Curves) setting set to in your definition?

Tried multiple combinations. Isocurves are in this file

PS: your object isn’t centered and the quad mesh is not symmetrical. You’d have to fix this by moving the base surface to the mid plane.

Great, thank you a lot

Another thing which helps with symmetry is to split the brep / surface with a vertical mid plane and use the hard edges option…

In the end you’ll have to tweak the topology by hand.

Is the helmet going to be open at the top?

You don’t need to set all curves as guide curves; you should slectively choose some curves ag the guide curves.

In this gh file, two curves were selected as guide curves.

I used quad remesh + (options) with a symmetry and hard edges on, looks about right

I’d change these two details…

Do you have an idea how to do it other than manually adjust single faces?

The sharp corner might be doable by modifying the input surface.

The inside corner above the ear is easier manually.

In general I think you get better topology if you do it manually. Then you’d need to worry just about morphing the good topology from a standard head to your custom head.
