An outline will only cut a single line
If you need an outline with a width, you need to use Corel's Contour tool
Make a circle with a thick outline and make a circle with a contour outline.....then look in Wireframe view to see what I'm talking about
No matter how large, or how fat you make the outline, it will still only be a single cut line
On the other hand, the width of your contour will dictate how thick your cut 'outline' is
Checking wireframe view, (it's what your cutter sees) is always a good habit to get into, especially if you're just starting
