Based on the hand drawn wall measurements is this possible to make a custom SVG formula? By the way, I remeasured last night and the arch begins 4.25” from the top, not 4”. When I made that years ago I was thinking of covering it up with fluted framing and it wasn’t as accurate as I thought. Anyway with the SVG parameters to cut out a wall hole with a 3-sided arch opening, would it do sharp corners or a rounded ellipse? I’m not sure how to define my shape.
