Hi Karsten,

Thank you for getting back to me.

<<used Concat2 for the Points???>>
I used Concat2 on num arrays only. The point arrays were interleaved with Test/BundleArray which works perfectly for the application.

<<it is easier to generate 2 curves for both directions and make then a pattern of the curves>>
Yes it is easier, but also more limited. Ultimately I plan to map point arrays to compound surfaces for topographic woven skin.

<<will try to find some time...and have a deeper look in the files.>>

Thanks Karsten, I greatly appreciate it.

All the best
James
