Didn’t want to hijack the thread on hip backing bevels, but the answer may be the same. Hopefully have attached a rough sketch.
Bay window area with the side walls angled 45 degrees. Have the hip rafters and necessary jack rafters in place. Tomorrow time to install the roof sheathing.
As an aside it’s the first time I’ll be working with the new roof sheathing that only needs to be taped, no paper work!
Question is what bevel angle do I use where the roof sheathing panels butt against each other over the hip. The main common rafters are 8:12.
If there is a reasonable way or method of calculating this, ie.with a construction master calculator, or some other method?
Let’s not confuse the issue with facts!

You building a watch or sheathing a roof?
I'd eyeball it close enough, never look at the angle thing on my saw. Worse comes to worse, just make it a 45 bevel and the top face will always be closed, unless yer at a severe change.
Once ya do that, you can work backwards and look and see what angle it is, but some angle scales on some tools is just a ballpark..LOL

gd,
If you follow this link : http://www.josephfusco.org/Articles/Roof_Cutting/Advanced/Octagon%20Calculations.html
at the bottom of the article it tells you how to find the plywood bevel angles using either a CM or a SC.
