No stroke in SVG export

hi everybody :)
I’ve got a (small) problem exporting a SVG file and importing it to illustrator. The file is a series of SVG polyline, but when i import the file in illustrator i only see the Path, not the Stroke of the polylines, so i don’t understand (in illustrator) how set the stroke weigth in base on the dimension of the file. So, is there a node that can export the polyline Stroke too? or is there any way to replicate the same stroke weight in illustrator??
thank you very much :)

sry, illustrator svg stuff bit different from svg implemtation in vvvv…

ah ok :P, thank you :)
