Forum Title: How To Scribe A Segmental Arch.
I'm framing a segmental arch across a 16' garage opening. I know how to scribe/calculate normal arches by finding the radius but the radius to this arch will be over 15 to 20' (i.e. take up too much room to layout). The opening is 16', the sides come down 8 on each side to 0 in the middle. What's the best way to scribe this without snapping a bunch of lines and rotating on a string?
