Blender tools update (what I have learned)

I have found out how to cut a hole in another shape in Blender using this simple tutorial, Tutorial link –>

This however failed to mention or I overlooked that all modifiers have to be applied already to the shape you are cutting a hole out of, I found this out through trail and error, first trying the other settings, thinking that my situation might be different, which is was, but not like that, I’m embarrassed that it took me so long to figure out, which was about 2 days, but now I can continue my progress.

These are 2 screenshots of without and with holes in to show you the difference it makes.
