Hi Neil Inglis,

I tested the same situation for both versions, I guess you are partially correct. If the angle is 45°, the pitch is 12:12, so you have 2m x 12:12= 2m
Anyway, in V8 appears 2m and in V10 appears 8m
I am reporting this situation to Punch right now

Thank you for report this

Patricia

Thanks Patricia for your input, lets hope Punch! can sort it. I actually found the ridge height value useful (as opposed to the slope length) as my planners wish to restrict total roof height so when I enter an eaves elevation I then have to check ridge heights for different slopes! I can see it creates a problem in estimator when it gives you short rafters! Patricia - when I gave example dimensions my span of 2m was across the full roof ie 2 sides. I think your numbers assume 1/2 a roof with just one slope. However no matter, you valdated it was a bug & not me doing something weird! Thanks to both of you for your ongoing invaluable help. Best wishes, Neil.

Oh Oh! Patricia - I agree with your sums! We just have crossed terminology. My span of 2m was all the way across & yours is 1/2 the way across. In my case I had 1m equivalent to your 2m which is why my ridge height was only 1m high. However we are both saying the same thing! I think I agree with you as well except perhaps when you say "The Ridge Height notation is correct, in both height and length" because, as Patricia agreed, the ridge length shown is correct but the height is not for V10. This is the bug that Patricia reported to Punch! Again thanks for your help. Neil.
