Loft-grid on surface

Hell,

I have a problem with loft function. I created a surface, mapped a hexagonal grid into it and created a grid of smaller hexagons inside the main ones (attracted by the curve). I would like to connect them so that hexagonal openings are created, but when I use loft function as in the tutorial everuthing looks like a disaster... What do I do wrong?

I put thhe printscreen on my file and the sketch how i'd like it to look

From an image is rather impossible to diagnose the Loft issue but:

1. Check profile directions (use DotProduct on Vectors, say, tangent at profiles start) or ... see 3.

2. "Align" Loft option works ... when it works (in most cases it fails).

3. If curves are sampled in some collection (List) there's a flip native component that works with a guide curve (say: the first item on the List).

4. Check span points (the more they "match" the "smoother" the Loft).

Other than that when dealing with hex combos take provision for creating planar "pieces" in order to unroll them properly for some sort of fabrication.

In fact I have exactly what you want but it's a rather complex C# combo (no native components at all) that works on any type of open or closed Brep (i.e. surfaces with trimmed info: holes and the likes) and with any number of attractors (in push/pull mode) . It does automatically the "layout" as well (unroll).

I am afraid i don't understand your combo.. ;( Could you tell me how to loft the 2 grids together so that each big hexagon is lofted with the samller above it, respectively?

I attach the file so that maybe its easier to understand what my problem is and help why it doesnt work

A classic mismatch case (among other things) that one ... and the shift paths was the tip of the iceberg.

BTW: what do you mean that you don't understand my "combo"? what combo? you mean the list of "possible" issues? (other than the total mismatch, he he).
