I ended up here with my wedge. It doesn’t look exactly like the video, I’m wondering if it’s due to the way I created the wedge in the first place, or how I rotated it? The instructor rotated on the X axis to get the pointy side up, I rotated on the Y. If I rotate my model on the X, like the teacher did, my model flops over on it’s side.
I’m just a student like you, but I’d argue that the coordinate arrangement doesn’t matter if the product is what you wanted; and it looks to me like you nailed it.
