Comment 1 for bug 1206420

I may be mistaken but if I understand correctly, this feature already exists (and seems better) in Inkscape. You should have a look at the clone tool,Edit → Clone → icon Create Tiled Clones...(cf http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Tiles.html). In your case it's as easy as setting 1 line 14 columns, and setting (in the translation tab) the right percentage of X translation by column.
