I want to delete a few lines, but the eraser leaves that ugly trace mark on the picture.   How can I get rid of the lines and delete what I want to delete from the file?

Don't use time from your busy day if it's not useful to the people you are using it for; this includes addressing clearly beginner/novice with understanding and thorough explanations. 

The OP was clearly confused and needed guidance. I don't care if your an "expert" of tech or AI, if you can't properly articulate the question and explain it thuroughly you aren't the right people to respond.

Now go away and address the questions at hand if you have anything to add and stop being butthurt about my response.
