Perp lines on pattern geo

[jameschadud (James C)]

Hello guys. Im having a small issue with a lunchbox pattern applyed on a curved surface. I am trying to to create a SDL line perpendicular to the vertices but it happens that each face has a different normal since its a curved surface.

Does anyone know how to make the overlapping vertices create lines on the same direction at the same time all of them going sort of perpendicular to the surface? Right now im only getting them to so all the same direction but at some point of the surface the result if not good anymore because they start to be paralled to the curved surface.

There is an image attached to show what is happening.

Thanks in advance

Thanks

If you need vertex or face normals use meshes instead:

Thanks for the repply Petras.

This seems a great option.

I just wonder if a can loft these perp lines since there is only one in each vertice. Like if I was extruding each face of the surface if you know what I mean. I attached an image showing what I have now only in one direction.

For curved surfaces you can only offset mesh.

The question is if you need planar cases. If you need planar ones only conical meshes are geometrically planar after extrusion:

Ellipsoid mesh from curvature lines

Hi, I would like to create a mesh based on ellipsoid curvature curves. First I was wondering to get curvature lines and intersect in u and v directions. But I believe there is some specific way to create a mesh of this form. Could someone point me where to start? I searching for only one form - ellipsoid similar to subdivision in these references [Conformal-mapping-of-an-ellipsoidal-test-body-creates-a-mesh-with-planar-quadrilateral_W640] [svg] [Lines-of-curvatures-of-an-ellipsoid-with-des…

Or you want pyramids but in that cases cells will not touch side by side

Hexagonal Cells on Enclosed surface

One of easier way is using plugin features like Lunchbox, Ngon, Weaverbird. This one is using Ngon+WB. [Canvas at 17;29;09] HexaGridPattern_re.gh (12.1 KB)

Or if you do not care about planarity just want individual cells
