That vertical line is part of an unfilled semicircle. You might be able to just delete it. However, it it's noticable, and you see that part of it is needed, then here's how to get rid of only the straight segment.
Select with Selection tool Path menu > Object to Path Switch to Node tool Click once in the straight segment (selects the nodes at both ends of the segment) Click "Delete Segment Between 2 Nodes" button (Node tool control bar)
All best, brynn

People,
How would I get rid of the fine, black vertical line in the centre of the top half of this symbol I created?
Thanks,
Phil.
