Cut the Door Opening

What happens here

Using a drill, create pilot holes within the marked cutting area, especially at the corners, to allow for the insertion of a jigsaw blade. Then, use a circular saw to make the straight cuts along the marked lines, being careful not to overcut. For the corners and any curved sections, switch to a jigsaw to complete the cut, following the template's outline precisely.

Goal: Create a clean opening in the door for the glass insert.
