that does not work for me. I can change settings for the height and width of the line_object - I can set the width to 5 for horiz. lines and the height to 5 for vert. lines (5 seems to be the minimum), but still, when I bring the two lines very close to each other, one seems to be covered by the other, there always remains 1+mm of white space between them.
That link does currently not work, I'll have a look as soon as it works.
Thanks a lot!
