Rounded ridge, those dashed lines are what I took as structural ridge beams. Still no matter geometry-math works the same. Just need to frame the round in between-above the structural beams.

Ain't my project. I'll let BlueRidgeGreen call me an idiot or understand where I'm coming from.

I used a construction master calculator once, pissed me off. Just used regular calculator that had sq root function and some quick sketches ... So it's fun once in a while to dust off and stretch the roof figuring-cutting brain cells.

3/8" ply for the curve. That should be plenty strong.

Doubled? I've made sail boats with 1/4" ply and longer spans between supports, no problem.

I didn't catch that it was doubled..

Edit: Upgrade from plan?

Re: Construction Math For Dummies


I'd lap splice the roof rafters (2 x 10s or 12s ), then cut away the radius needed, a high cross tie? or ridge board in the center, exposed? maybe a timber?

Thoereically you could use the cut offs to make the inside ceiling peak radiuses.
fewer pieces? maybe a extra short curved rafter under the curved plywood to "suck" it down between rafters

No venting on a tar paper shingled roof?

Can you warranty that curved/flat surface?

I don't like near zero overhangs with supertight homes, where does the wet air from behind the walls' Rainscreens get to daylight?

Weíre getting there.

Iíll caption the videos soon and try to give the highlights of each phase.
(Like the elevations on the site plan being off 9í, causing me to have to cut the top of the hillside off....)

Digging into the most complicated mathematics right now with wall framing.

Re: Construction Math For Dummies


Great work as usual!

On the left, it looks like you are setting and bracing corner studs. Are you taking a chalk line corner to corner, and using that to stand studs to mark in place, or did you come up with a calculated cut list? Or maybe something different?
