Diagonal lines on Surface

Hi Guys,

I can't for the life of me figure this out. I need to finish the diagonal lines on the surface below which is going to be a diagonal weave. I can get all the lines drawn except the last half of the one direction. All the flipping and reversing doesn't get me the last bit. Anyone have any idea?

As shown in my definition, I'm currently Shifting the list of points by one, then using Flip Matrix.

Hi Matt,

I am using an older version of gh, and some components are missing when I open your attached file. You did post the definition preview too, but I seem to be too lazy to recreate it.

Maybe you could use the Lunchbox's Diamond panels component instead, then get edge curves from those dimaond panels. Like so:

Or instead of that do you want to have a continuous diagonal lines?

Yeah they need to be continuous as they will start to weave and go through each other. I actually have that part working, it's just this!

Try this:

But it takes equal division of diagonals in both direction:

That gets the desired effect, but only on a flat plane. I need the lines to follow the diagonals of any surface :/ Thanks though!

If your surfaces are always going to be somewhat parallel with XY plane, than you can use the attached definition.

Thanks again! This will have to do for now, though hopefully I can figure out the initial problem eventually. Maybe if I stare at it long enough it will do something different.
