Here we consider two types of hipped roofs see picture.
Centered irregular hips require backing at least on the steeper side which would stand proud if not backed shifting them plans both square shoulders to the same hap for each roof.
A regular hip has equal slopes on all sides while an irregular hip has different slopes on the main roof and hip end roof.
For irregular or bastard hip roofs the roof eave angle can be between 35 and 150 you ll get an unconstructable error message if the roof is unconstructable with the current input parameters.
