A good number of kits (at least aircraft kits) have way overdone panel lines that if scaled up would be like huge gaps/
I feel like if a kit needs panel lines, or has raised panel lines that you want to convert, it is better and easier/more forgiving to get a really fine mechanical pencil or similar to draw them on instead of scribing. Except for maybe certain areas that represent parts not actually joined or certain removable hatches etc...
also note, in some cases, raised panel lines are actually accurate
