Has anyone else had a problem where they have random lines showing up on a drawing and can't select them?   I have a very large drawing that I was adding center lines to some of the views for dimensioning to a pattern.  Now I can't select those lines, they are there, some of them even extend the view border, but I can't click on them.   Basically this is making a drawing that I spend about 10 hours on useless becuase I have extra lines flying around that I can't delete.  One of wich is about 1000 times longer than the sheet so when I slect zoom all the line is all I can see with a dot at one end that is the sheet.
