You drew model lines, yes? Model lines exist on a surface. Something is
above the lines (such as your floor) and hiding the lines. Sounds like you
should have been using detail lines which are always on top and view
specific.

But now they don't seem to be there. I can see them when I select them but
its like they're invisible. And when i underlay that floor in my first
floor I can see them. I also checked the visibility parameters, and the
lines family is on! I feel so frustrated not resolving something I'm sure is
a simple solution. Please help! thanks.
