How do I cover up lines in solidworks drawing

I need to cover up some lines in solidworks drawing. I dont want to change my model to get rid of the lines, nor do I want to start the drawing from scratch.

I just need to get rid of a few visible lines on my model, so when I export to PDF they dont show.

I can edit the drawing with a pdf editor and get rid of them this way, but Im afraid it will worsen resolution and increase file size.

Is there a way I can cover up the lines directly in solidworks drawings?

I tried importing a blank Bitmap file and stretching it to cover the lines, but solidworks forces the bitmaps to be layered under the lines not above, is there a way I can change layering order?

Thanks,
