Byrnn, that makes sense and it was the stroke width that I was having problems with. After pasting I wasn't able to change the stroke width for me to see the line. Though, I was able to copy and paste what I was working with to an new file and it work fine now.

Thanks guys for looking into this.

Every time I copy and paste a vertical line it has a width of 0. The issue is also with horizontal lines pasting with a height of 0. I must have clicked some where I shouldn't have.
